Do-it-yourself ballu thermal curtain repair

In detail: do-it-yourself repair of a ballu thermal curtain from a real master for the site my.housecope.com.

Large and long air curtains with large fans break more often. The fan cylinder often fails due to overheating. This is one of the most common breakdowns. Temperature control will help to avoid such a breakdown. Do not set the regulators to maximum for long run times. If you had to use this mode, then after a while it is necessary to transfer the heat curtain to a moderate mode of operation.

It is also impossible to hang the curtain incorrectly. The heat curtain intended for horizontal installation should be placed horizontally, and vertical - vertically.

Also, when replacing parts, boards, microcircuits, sensors, etc., you should install only original spare parts, since only they can give you a guarantee of long-term operation.

The best thing you can do in this case is to carefully study the operating instructions, and do everything that is prescribed by it, and what is listed in this answer, as well as contact the service that carried out the installation and commissioning in a timely manner.

For information on how to clean the heat curtain, see the attached video clip.

Many public enterprises, trading companies, shops and offices with a high traffic of people per day prefer to install a thermal curtain over the entrance to the premises. The principle of operation of this climatic technology is based on the supply of a stream of hot air, which becomes an obstacle in the path of cold air. In our cold climate, the operation for air curtains has been going on for more than six months, so it is not surprising that the device often breaks down and stops performing its function.

One of the most common reasons for the breakdown of climatic equipment is overheating of the device. Most often, the owners of the equipment do not follow the recommendations set forth in the instructions and turn on the device at full power, allowing it to overheat. In the event of a breakdown, the following most often suffer:

The climate system can stop working even after improper installation. According to the service centers, the repair of heat curtains, the length of which is more than 80 cm, is more often carried out. This is due to the fact that these devices require the installation of a more complex internal filling, which breaks when overheated.

Repair of equipment is carried out by specialists of service centers who visit the site to assess the breakdown and the possibility of its elimination. Specialists can fix most minor faults on site; such work does not require much time. If you decide to fix the malfunction yourself, then you need to study the instructions in detail, find out which part needs to be replaced and whether it is possible to purchase it. Before carrying out repair work, it is necessary to completely disconnect the device from the mains, remove it. All work is carried out in compliance with safety regulations.

The main faults that you can fix yourself:

The curtain does not work when connected to the electrical network. It is necessary to check the presence of electricity, the fuse of the device and the contacts.If the fuse and contacts fail, you can replace them yourself, following the attached instructions.
The switch of the device is in the “Heating” position, but does not perform this function. A possible cause is a failure of the switch or poor contact in the electrical circuit. The switch can be replaced by yourself, the contact is restored by checking the correct connection.
During operation, the device may periodically turn off and on. It is necessary to check the correctness of the installation of the device, to clean the inside of the accumulated dust.

The air curtain will work properly only if you follow all the recommendations for its installation, periodic cleaning and maintenance.

We have a household heater ballu 1500 # 1 among heaters, although I would argue with that.

At one point, the heater power button shorted out, lit up and everything melted. It was thought for a long time that the entire heater also burned out. Since they requested 700 rubles for diagnostics at the ballu service center, I decided to go to the store and buy a new button, at least it costs 60 rubles. Before disconnecting the old one, you need to photograph all the wiring in order to connect the new one without problems and not make a short circuit.

ballu heater repair

After dismantling the old button and inserting a new heater, it did not work, after which I began to turn off each of the sensors that are in the heaters in turn in order to identify the cause. He was the first to turn off the power regulator by connecting the wires directly, it did not help, then the overheating sensor did not help.

And I got to the last black box, disconnecting the wires from it and connecting it directly without it, everything worked.

ballu 1500 DIY heater repair

To identify the cause, I decided to disassemble it, inside there was a sensor and a heavy round ball.

circuit sensor for ballu heater

Having opened the sensor, I realized that it was 100% working and then it dawned on me that this is a black box, the position of the heater, I tested everything in a horizontal position, which means that the ball did not press on the electrical circuit closure sensor and the current did not reach the ten, putting the fan correctly and collecting everything back, everything worked successfully.

If the fan heater does not turn on when connected to the mains and pressing the button, there may be several reasons for the malfunction. The first thing to do is to check the electrical cord, it may have been interrupted somewhere during summer storage. Did not help? We take a screwdriver and a multimeter, after which we proceed to self-repair the fan heater. The most likely cause of the malfunction is the fuse box, one of which has tripped due to overheating.

Using the Scarlett household heater as an example SC158 we will consider in the form of step-by-step instructions how to fix a fan heater with our own hands:

First, unscrew the screws on the back cover, there are usually 6 of them, as shown in the photo.
Next, we ring the main elements of the circuit with a multimeter: thermal fuses, a thermostat, a thermal switch. The first fuse can be seen immediately without removing the blades. To find the second one, which is on the engine, you will have to remove the fan. You call the circuit with a multimeter on your own and if the reason is really this type of breakdown, you buy exactly the same element in the store and replace it (the cost is not more than 30 rubles).

We draw your attention to the fact that it is strictly forbidden to replace the fuses with thin wires (bugs). With this method of repairing a fan heater with your own hands, you will make a fire hazardous heater that will not work when overheated!

The second popular failure of a fan heater is blowing, but not heating the air. In this case, the cause of the malfunction is most likely a heating element - a spiral or a ceramic heating element.Everything is simple here - you check the resistance in the circuit with a multimeter and if an open circuit occurs somewhere, you need to replace the heating element with a new one. Sometimes it happens that the heater stops heating because one of the sections of the spiral is damaged. In this case, you can try to repair the fan heater yourself by connecting the nichrome spiral.

It is also not a rare case when the same fuse is the cause of a breakdown. If the fan heater does not heat up, check the fuses using the technology provided above.

In addition, the bimetallic thermostat often fails (shown in the photo with a red arrow). For repair, you just need to clean its contacts yourself to a metallic color and warm it up yourself with a soldering iron. The thermostat should behave as follows: when heated, the contacts must open the circuit, when cooled down, close again. If the device does not work, try to manually close the temperature controller and connect the heater to the mains. If it is a worker, the spiral should be heated.

If the fan heater works, but the fan does not turn, the most likely cause of the malfunction is the motor stopped working. What to do in this case? Ring the part with a multimeter and check the insides. Perhaps the bearings are simply worn out and need to be replaced. We talked about how to use a multimeter in the corresponding article!

Another breakdown option is heavy dust pollution, as a result of which the fan does not spin or often turns off. Try to repair the motor yourself by wiping it with a rag and dripping a little machine oil between the moving and stationary parts. Did not help? We replace the broken electric motor with a new one with the same characteristics.

Well, and the last malfunction - the fan heater does not heat the air well. In this case, the cause of the breakdown is contamination of the spare parts. Most likely, the heating element is covered in dust, as a result of which heating occurs weakly, for example, at the second speed, as at the first. For such an easy repair, turn off the power and use a dry rag or vacuum cleaner to walk over all the elements of the circuit, the main thing is not to damage anything. Did you do it, but it doesn't help? Check the electrical plug, it may be at fault. Turn on the heater for a few minutes, then remove the plug from the socket and feel the electrodes. If one of them is noticeably warmer than the second, the electrical plug is broken, as a result of which the household heater produces little heat.

That's all the tips for repairing a fan heater with your own hands! When choosing a heater on your own, we recommend giving preference to models with a ceramic heating element, rather than a spiral. You can read more tips on choosing fan heaters for your home in the corresponding article!

During the operation of the product, malfunctions can occur, most of which have typical causes. Below is a list of these causes and recommendations for their elimination. It is important to remember the safety precautions when attempting to correct the problem you are experiencing.

If the curtain does not turn on:
• Should check, is there voltage in the network, in phases.
• Check continuity of the cable and repair breaks if they are found.
• Check according to the instructions, whether the distance from the remote control to the infrared sensor is correct. If exceeded, place the remote control in the desired range and at the desired angle.
• Check batteries inside the remote control, replace them if necessary.
• Check IR03 control panel for serviceability, referring to its instructions.

If the air comes from the curtain, but is not warm, then the emergency thermal switch has been triggered. This could be due to a number of reasons:
• Contaminated, or the curtain windows are obstructed, which prevents normal air circulation.
• Has broken fan.
• The veil was turned off not according to the rules, bypassing the purge mode.
• Set too high temperature for the existing area of the room.

It is necessary to turn off the product from the network, wait until it has completely cooled down, eliminate the detected causes, and return the emergency thermal switch to the ready state. More details on how to do this are described in the instructions.

If the control panel fails to turn off the curtain, it means that the starter is jammed. It is necessary to turn it off through the circuit breaker and replace the starter.
If the curtain works, but does not inflate the set temperature:
• The wind strength and temperature have noticeably changed, it may be worth temporarily closing the opening mechanically.
• Too large flow of people. Open another opening with a curtain, or temporarily install a fan heater.
• Supply and exhaust mechanical ventilation is unbalanced. Indoor pressure is lower than outside. Check the pressure in the room, increase the ventilation flow.

A thermal curtain is a climatic equipment, which is a type of room heating. The device, design, characteristics of such devices are different, but all devices have a single principle of operation. The process of connecting and choosing a heating curtain requires special attention, since safe and efficient operation depends on it.To regulate the microclimate, a device such as a heat curtain is often used. This equipment is a powerful fan heater, which is housed in a metal case, often of rectangular elongated shape.The thermal curtain is installed above the front door and does not spoil the interiorThe equipment design contains the following elements:

air duct through which warm air masses are carried;

heating elements in electric models - ten, and in water - pipes;

radial fans or turbine have parameters that depend on the length of the heat curtain;

filters clean the air coming from outside from dust and debris;

the body has perforated walls for the intake and output of air streams;

control buttons are located on the side panel of the device.

The device is easily wall-mounted and provides warm air flowThe thermal curtain is designed to regulate the microclimate and distribute temperature zones in different rooms. Often the equipment is installed above the entrance from the inside of the room, which protects the space from cold currents and ensures a comfortable temperature. This solution is optimal for a private house, shop, shopping centers and any other buildings where the front door is often opened and cold air enters through it. At the same time, safety requirements prohibit the installation of curtains in rooms with flammable materials, in transport, mines, automated production facilities.The simple operating principle of the curtain is ensured by the well-thought-out design of the device. A powerful fan draws in air from the outside, after which the masses pass through the filter and are cleaned of dust. Further, the air moves through the area of the electric heated spiral, the temperature of the flow rises and it enters the room through the nozzles. The direction of the jet can be vertical or horizontal. Image - DIY ballu heat curtain repair

The air entering the room is cleaned of dirt, heats up and enters the room

The distribution and intensification of the warm air flow is due to the fan. The power and speed of the equipment can be different, and the functional models have buttons and switches that allow you to set the operating parameters.

The range of air curtains includes several types of devices that differ in design and appearance, location. Electric models are in demand and practical in operation, but they consume a large amount of electricity to heat the air.The heating element in such devices is an electric spiral.

Electric models are easy to use but not economical

There is also a water type, in which a heater is present. This element can withstand drops and low temperatures, which ensures the reliability of the equipment. The device is connected to a central hot water supply, as a result of which the installation and the cost of the structure are higher than those of electrical options.

Water models are difficult to install and have a high cost

These options are the main and most demanded for providing heat at the entrance to the room. The sizes and power of the devices are presented in various versions, which allows you to choose the optimal equipment depending on the parameters of the opening, the outside air temperature and the desired level of heating inside the room.

Before installing the device, it is necessary to take into account that the heat curtain must correspond to the width (when placed horizontally above the door) or the height of the opening (when installed vertically on the sides of the opening). To do this, you need to select equipment of the appropriate length or install several devices in a row. The installation of an electrical model is the easiest, and the following materials and tools will be required for work:

screwdriver, screws, pencil;

building level, tape measure, puncher;

fittings for fastening included in the set of the thermal curtain;

a pendulum suspension is required for ceiling mounting;

if several devices are fastened in one line, then a connecting kit is needed;

M10 bolts, nuts and screws, consoles.

Pendulum hangers are required for ceiling mountingWhen purchasing brackets or hangers for fixing, consider the weight of the equipment. Such parts may be included with the device, but you can pick them up separately.For openings less than 1.5 m wide, horizontal placement is optimal, which implies mounting the device above the entrance to the room. In this case, the curtain can be installed on the ceiling or above the door. Thus, the device can be fixed against the wall or suspended. Other options for placing the curtain are also possible, each of which has certain features.The curtain should be equal to the width or height of the openingHorizontal fixation can be carried out on the ceiling or on the wall above the opening, as mentioned above. The second option is the most demanded, as it allows to more effectively prevent the ingress of cold air into the room than when installed on the ceiling. In this case, the air flow will be directed from top to bottom. Image - DIY ballu heat curtain repair

Horizontal mount protects well from the cold

For installation, the following basic steps are performed:

Unpacking equipment, checking the number and type of fasteners.
About 10 - 15 cm recede from the upper edge of the opening, draw the bottom line with a pencil, on which the body should be located.
At a distance equal to the length of the body, the attachment points of the brackets are marked, holes are made there.
The brackets are screwed with bolts and nuts to the body, and then the entire system is fixed to the wall.
The equipment is connected to the power grid, its functionality is checked.

Detailed instructions, taking into account the individual characteristics of the device, are supplied with the thermal curtain. Therefore, before installation, you should study the manufacturer's manual.

Placing devices on the sides of the opening to its full height is a vertical method of installing thermal curtains. This technology is optimal if the horizontal method does not allow covering the entire opening area with a warm air flow, as well as with an entrance width of more than 2 m.

Vertical placement requires more devices than horizontal placement

Installation is carried out according to the instructions, but the main stages of work are expressed in the following:

From the edge of the opening, you need to retreat about 10 cm and mark the fixing points of the brackets.
The fasteners are installed in the prepared holes and on the body.
If necessary, connect several buildings with special elements.
Check the equipment performance.

The installation of elements vertically is carried out using the same technology as horizontally. In this case, the housings are fixed on both sides of the opening, which will provide good protection from the cold.

Modern equipment has a flexible cable and plug, which provides connection to the mains through the socket. If a stationary installation is carried out, then it is possible to connect the curtain through a central-type switch, which has an air gap and a parameter of 3 mm. This connection option is always carried out by an electrician.

Installation can be done independently, but the connection is carried out by a wizard

The connection diagram of the heating equipment to the central switch is developed individually. It is simple to connect one device, and for this two wires from the curtain are led to the corresponding network cables, taking into account the location of the "zero" and "phase" wires. For safety, an RCD unit is added to the chain, which can turn off the system in an emergency. The chassis and all power parts must be grounded.

The most famous manufacturers of climatic equipment are Teplomash and Ballu. Each manufacturer, complete with equipment, provides detailed instructions for connection and installation, but the main features can be considered separately.The Ballu brand produces a variety of models of thermal devicesFeatures of connection and operation of Ballu equipment are expressed in the following:

connection to the mains is carried out through a circuit breaker;

when installing fixed wiring, use a three-core cable with a minimum cross-section of 1 mm 2 over a copper conductor. The electrical network to which the curtain will be connected must provide protection of the product against overloads and short-circuit currents;

to install the control panel, unscrew the screw, remove the top cover and panel of the panel, fix the panel on the wall, install the panel and top cover.

Devices of the "Teplomash" company have a simple design and are affordableThe device of the "Teplomash" company assumes control of the curtains from a remote or remote control panel. The degree of protection of the control panel shell is IP20. When controlling the curtain from the remote control, the distance to the infrared receiving device on the remote control must be up to 6 m and the angle up to 60 °. The curtains are connected to the network through a circuit breaker and a residual current device (RCD). RCD trip current - 100 mA. The curtains are powered from a three-phase electrical network with a voltage of 380 V / 50 Hz. The control panel assumes the introduction of a control cable 7x0.5 mm using the "hidden wiring" method. If it is necessary to connect the cable with "external wiring", then a 50x10mm recess should be made in the wall at the point where the wire is exited from the control panel body.The selection, installation and connection of air curtains from different manufacturers presuppose adherence to general rules, including taking into account the required functionality and device parameters. Correct further operation will ensure the safety of the equipment.To heat various rooms and maintain the required temperature, we are faced with the question: What kind of fan heater should be purchased?- And we need to approach such a question rationally and economically.Economical - taking into account the consumption of electrical energy. Reasonable - from the point of view of choosing this product for a fan heater. Image - DIY ballu heat curtain repair

Currently, we are simply at a loss in front of such a choice, since there is a wide range of products on sale:

various designs;
various types of modifications

and the power of fan heaters.

So what kind of fan heater do we need to buy ?:

IRIT IR - 604, power 1000-2000 W;
Delta B - 801 - 1, 2000 W;
WATT WCH - 1500, 1500 W;
First TZ - FH3, 2000W

I would believe that the following conditions should be taken into account when purchasing:

area of the room;
time of heating the room with subsequent maintenance of the required air temperature;
type of premises.

- premises, when purchasing, should not be neglected in the advisory approach to such a solution to the issue. This implies the advice of the seller-consultant himself in choosing a heater.

To successfully carry out repairs to troubleshoot fan heaters, you need to know - how these heaters are arranged.

Both the electrical circuit itself and its individual elements included in the circuit do not require great knowledge of electrical engineering in their understanding.

What is the point here? - The bottom line is the very value of the resistance of the fan heater.

From the section on electrical engineering, we know that the lower the resistance both for the electrical circuit as a whole, and in particular for the heaters, the greater the current value will be accordingly.

To put it more simply, the less the resistance of any heating element, the heating coil of the fan heater, the greater the degree of heating.

Of course, fan heaters have their own permissible resistance value. Consider the electrical diagram of fan heaters intended for connection to a two-wire single-phase network.

As a rule, for safe use of fan heaters, their grounding must also be taken into account, that is, the combination of a grounding device with the metal casing of the fan heater.

This electrical diagram Fig. 1 of the fan heater consists of:

switch SA1;
two thermostats SK1, SK2;
electric motor M1;
heater EK1.

The electric motor in the electric circuit is the electric fan, which creates air injection to the heater.

The EK1 heater can be an ordinary electric heating coil made of nichrome.

The SK2 thermostat provides the preset heating mode of the EK1 heater for this circuit, from 5 to 40 degrees Celsius. Timely shutdown is also ensured upon reaching the set mode of the heater heating temperature.

The heater is switched on and off here due to the heating and cooling of the bimetallic plate of the thermostat, which is the switch contacts.

The diagram shows the connection of the ground wire to the metal casing of the fan heater. The connection of the fan motor and the EK1 heater is parallel in the electrical circuit.

SA1, SK1, SK2, - have a serial connection in the circuit. The electrical circuit for this circuit is closed at the electric motor and heater.

Possible reasons for a fan heater malfunction may be:

oxidation or burning of contacts SA1, SK1, SK2;
burnout of the copper wire in the stator winding of the electric motor;
burnout of the heating coil of the heater;
burnout of the wire in connection with the plug;
burnout of the wire in the contact connection with the heater;
mechanical damage to the wire in the network cable

Consider the following diagram, a diagram of a three-phase fan heater TVK 612; 912.

three-phase fan heater TVK 612; 912

The three-phase fan heater consists of three heaters EK1, EK2, EK3. Two phases L2, L3 are connected through a contactor to heaters EK2, EK3.

Phase L1 is connected to switch SA1 through disk thermostat SK1.

From the switch, as seen in the diagram, there are two taps from phase L1. One branch of the phase current L1 through the switch SA1 goes to the contact connection with the electric motor.

Another branch of the phase current L1 is connected to the contactor KM1, then the phase L1 is connected to the first heater EK1.

The neutral neutral wire also has two branches. One branch of the neutral wire is connected to the electric motor, that is, the electric motor is connected to an external voltage source 220V, phase L1 and neutral.

Another neutral branch is connected via a contactor to the switch. In other words, by closing the switch contacts, the operating mode of the heaters can be controlled.

The electric motor, as shown in the diagram, is electrically connected to the body by ground, just like the body of the fan heater itself, namely, the body of the electric motor and the body of the fan heater are connected to ground.

I believe that it is not so important here to learn how to outline all the available connections for a given electrical circuit. It is enough just to carefully trace its individual sections.

The principle of operation of a household fan heater is the same as that of a heat gun that heats, for example, a warehouse or some other room.

To diagnose the fan heater circuit for individual sections of the electrical circuit, individual elements that are in the electrical circuit, it is necessary to disassemble this heating appliance.

To disassemble the fan heat, you need a screwdriver for the corresponding screw head. With such a diagnosis, you will need:

probe or indicator screwdriver with batteries;
device Multimeter or Ohmmeter.

Diagnostics both for individual sections of the electrical circuit and for individual elements included in the electrical circuit of the fan heater can be carried out with a probe. Currently, there is a wide range of different probes on sale, for example, in my practice I use the Navigator NTP-E probe, since I also need it for work on the electrical part.

The ohmmeter device is necessary after all the electrical connections have been made, because before connecting the fan heater to the outlet, you need to check the heating appliance for resistance.

After removing the cover, we turn our attention to the fuses, which are in the electrical circuit. Fan heaters usually have a blown fuse.

In the photograph, we can see the fuses with the designation of the pointing arrows:

blue arrow - fuse;
yellow arrow - overheat fuse.

This photo shows a fuse with a rated heating temperature of 121 degrees Celsius.

The heating element is the heat of the fan, as can be clearly seen in the photograph, it is made in the form of a spiral, nichrome is used as a material.

When replacing the heating element, the following is taken into account:

resistance of heating elements;
power of heating element.

Diagnostics for the electric motor circuit of the fan heat is carried out taking into account the resistance measurement:

stator windings;
rotor windings

and detailed information on diagnostics of an electric motor can be found in this website.

Like any other equipment, air curtains require regular maintenance and repair. So that the breakdown does not come as a surprise, and the repair of heat curtains does not cost a penny, experts recommend adhering to a competent system of scheduled preventive preventive examinations.

So, let's determine the list of works that must be performed regularly in order to prevent the failure of the thermal curtain:

First of all, you should remember the basic rule, before each start it is necessary to carry out a visual inspection of the installation. It is required to check all air intakes and air supply ducts. They should be free of foreign objects and it is recommended to systematically remove dust.
The condition of electrical power cables and control lines is checked. If the insulation is broken or other visible damage is present, measures must be taken to eliminate them.
In accordance with the operating instructions, it is necessary to lubricate all moving parts of the device. This list primarily includes a fan, blinds that change the direction of the air flow.
For water curtains, the main problem is considered to be the poor quality of the water used as a heat carrier.Therefore, it is necessary to regularly monitor the condition of the installed filters, if necessary, clean them.

If you carry out such a complex of works, as well as follow other manufacturer's recommendations, then the repair of heat curtains will not have to be performed soon.

The most typical malfunctions include the following breakdowns:

Water thermal curtain device

In most cases, breakdowns are associated with the failure of the fan or heat exchanger (heating electrical element). If we talk about malfunctions of fan equipment, then it is worth noting the fact that such a repair of heat curtains is most often necessary for installations whose length exceeds 1 meter. In such devices, the fan has to work with an increased load caused by the increased aerodynamic resistance of the unit.
For thermal curtains with a central location of the electric motor, failure of individual heating elements is characteristic. This is due to the impossibility of providing uniform airflow to the heating surfaces. Most often, the repair consists of replacing the heating element.
For water heat curtains, the main causes of malfunctions are mainly due to the ingress of debris or foreign objects into the heat exchanger. Violation of the circulation of the coolant leads to a decrease in thermal power or even depressurization of the device.
But most of the systematic malfunctions occur in the control circuits and devices for monitoring the operation of the heat curtain. That is, the automation system is considered the most vulnerable point.

In most cases, only specially trained personnel can repair the heating curtain. And if preventive work (cleaning, inspection) can be entrusted to your employees, then repairs should still be entrusted to professionals.

So, when is it necessary to call the service department and call a competent specialist who understands thermal curtains:

Decrease in thermal power of the flow in comparison with usual indicators.
Reducing the speed of air movement and the inability to block the entire section of the opening with the flow.
The appearance of extraneous knocks and noises during the operation of the installation.
Detection of coolant drips in units with a water heat exchanger.
Unstable or incorrect operation of automatic and remote control systems.

Well, the most important reason to think about the urgent need to repair the heat curtain - the unit simply does not turn on.

Remember that only a professional electrician or mechanic can diagnose and find the cause of the malfunction. Any independent attempt can only exacerbate the problem.

Therefore, you should not experiment, performing work by trial and error, such amateur performance will lead to additional costs. If you find any signs of malfunctions, immediately call the wizard.
