The Planar air heating device manufactured in Samara is very popular. If there is not enough warmth in the car, it is an indispensable assistant, even in the most severe winter domestic weather. In the cabin of a small passenger model or a spacious van, the driver and passengers become as comfortable as possible in a short time period.
The operation of the device is based on a simple principle - drawing the surrounding air masses inside the heating chamber. When the fuel burns, heat energy is released. It is directed to heating the air, which then enters the interior of the passenger compartment.
One of the advantages of the planar heater is the ability to adjust the heating power. For this, the device has a special knob on the regulator, which can be easily turned and set to the desired position.
Having set the desired power value, there is no need to interfere with the further operation of the device. It will be monitored automatically:
The Planar heater device includes not only a power regulator in the form of a rotary knob, but also a timer. The latter is necessary in order to turn off the installation after prolonged work.
The device is designed in such a way as to make the work autonomous in all aspects. Automation also monitors the current state of each work item located inside. The ignition process begins only when the control element is convinced that all components are in good working order. Thus, a very high level of safety during operation is achieved.
In order for the resulting flame to remain within the normal range, it is monitored by a corresponding indicator. If the temperature limit is exceeded, the control unit will stop burning.
Despite the high level of automation, shutdown of the device is supported in manual mode. The combustion chamber begins to ventilate. The fuel supply is completely cut off.

Some features of the Planar heater device
Typically, fuel enters the combustion chamber of the appliance directly from the vehicle's fuel tank. However, this option is not the only one possible. Sometimes the device has its own container, into which the fuel necessary for operation is poured.
The power supply is arranged by analogy. The planar heater is powered directly from the car battery.
The number of components of the heating device is huge, but among them there are three main elements:
Control panel or block - necessary to control the operation of the device as a whole
Fuel pump - needed to supply the required amount of fuel to the storage chamber
Heating element - air is heated in it, which subsequently enters the car interior

Of course, the Planar heating device is very useful and irreplaceable in cold winters. However, many motorists do not risk installing it, as they are afraid of incorrect operation in emergency situations.
The engineers took into account all possible features of the device's operation in various conditions. Let's consider some of them:
The operation of the heater is constantly monitored by the automatics. If it is defective, the warning LED (orange or red) lights up
The device will not allow the heat exchanger to overheat - in such a situation, it will turn off
There may be cases when combustion stops for spontaneous reasons - in such situations, the installation is automatically turned off.
As a result of an unsuccessful start of the heating equipment, the automation will make several repeated starts. If each of them fails, a fault warning will be issued.
Constant power surges can be very unsafe. The control unit will ensure the operability of the device only in situations where it does not go beyond the normal range:
Onboard voltage 12 V (device 4DM-12) - from 10.5 V to 16 V
Onboard voltage 24 V (device 4DM-24) - from 20.5 V to 30 V
Overheating is often caused by improper installation of equipment. It occurs when the inlet and outlet of the heater have been blocked.
Among car owners, especially truckers, who spend most of their time on the road, the planar heater deservedly receives a lot of positive reviews. Domestic development, in comparison with imported counterparts, is reliable, but less expensive.
A large number of positive characteristics are distinguished:
By inserting the air vents into the cargo hold, the entire vehicle can be heated, not just the driver's cabin.
Even at significantly low temperatures (less than -20 degrees), their efficiency remains at a very high level.
Saves fuel and battery life
Sufficient power indicator
Unlimited installation runtime
The planar heater is widely used in cars used to transport medicines, drinks, animals, process fluids, etc. They are actively used by drivers of kuguns, cranes and other special equipment.
To use the Planar heating unit, it is not necessary to start the car engine. This makes it possible to continue to operate it during the night.
Several models are offered on the market, each of which is characterized by its inherent features. However, the most popular among them is the Planar-4dm 24 model. Its installation is possible not only in large vans, but also in cabins, booths, etc. During operation, the heater practically does not emit noise.
One of the main aspects of using the Planar heater is compliance with safety regulations. Let's consider the most significant rules:
If the device has been turned off, it is allowed to turn it back on only after 10 seconds.
Do not turn off power during the purge cycle.
The heater must be disconnected from the mains if the body is being welded
It is recommended to turn off the device when refueling the car.
Do not use the heater indoors.
Having installed such a device, it is necessary to have a bucket of sand nearby and a working fire extinguisher
It is forbidden to lay fuel pipes inside the passenger compartment, however, they must be reliably insulated outside.
In the event of a breakdown, it is not recommended to repair the equipment yourself.
Everyone is able to install a planar heater independently. However, for greater confidence in its subsequent reliability and performance, it is recommended to entrust this process to a professional.The cost of services is relatively low and significantly lower than the cost of possible restoration or repair.
The considered device for heating cars in the winter or small, but necessarily well-ventilated rooms (gatehouse, change house, etc.) is in demand. However, without looking at the many benefits, cost can be a bit of a hurdle. Average prices for various models start at 18 thousand rubles.
As mentioned earlier, the installation of heating equipment can be done independently. In order to save time and for greater reliability, you should contact a specialist whose service cost starts from 5-6 thousand rubles.
The "Planar" autonomy is an air heater developed by Russian specialists, which is manufactured in Samara. The range of these car heaters consists of four devices (Planar 2D, Planar 4DM2, Planar 44D, Planar 8DM), each of which is available in two versions - 12 and 24 Volts. Even in severe frosts, such an installation can provide an optimal air temperature in the vehicle interior. First, we will briefly consider the device and the principle of operation of the heater, and then we will study all the Planar errors (fault codes) and their decoding.
Autonomous heaters "Planar" are equipped with a power regulator and a timer. The installation can work autonomously at all stages. The electronics starts the ignition only if the various components are in good working order and the required conditions are met. Therefore, you should not worry about the safety of using the device.
The main components of the "Planar" autonomous system:
block with control panel;
a heating element;
fuel pump.
Heaters from this manufacturer operate on the principle of supplying outside air to the heating compartment. During the combustion of fuel, energy is released that heats this air. Only then is hot air supplied to the vehicle interior.
To select the optimal power, a special regulator is used with the ability to be fixed in a given position. After the user selects the optimal operating mode, the heater will independently maintain the set temperature.
The basic principle of the "Planar" autonomous system:
Purging the combustion chamber.
Heating up the glow plugs to the required temperature.
Supply of the optimum air / fuel ratio to the working chamber.
Combustion of the air-fuel mixture.
Switching off the candle after stabilization of the temperature mode selected by the user.
We decided to publish the Planar autonomous system malfunction codes in the form of four tables. A specific heater model is indicated in front of each of them, which will help you understand what the problem is in your case.
Here's a thing: the car has been standing for a year already, it naturally clogged and smoked, cleaned it, put it back in place, we start it, but it does not start, as it thought with white smoke and smokes, due to errors, the peephole blinks 2 times. It is either there is no fuel or there is a problem with the air pipes, but there is no problem with either. The exhaust pipe was also covered in soot, cleaned. Who faced such a problem?
Found the reason for the glow plug! When dialing, it gave the resistance of a new candle when 15 volts were connected, it heated up by 2 mm and started to smoke, i.e. completely burned out.
Thank you, but about the side holes, I explained a little differently. Here are these holes from the inside, why are they needed:
Or does this shell have to be pulled out after installing the mesh? If not, then when you insert the mesh, how should they be positioned in relation to the fuel inlet, was it not for nothing that they were made?
Some of the nuances of repairing the Planar autonomous system: diesel fuel flows on the Planar autonomous system, smoke goes into the autonomous cabin.
Repair of the prestarting heater Webasto ThermoTop E (2004, petrol) - replacement of the evaporating mesh in the non-separable one.
Heater planar 4dm2 24 is another air-type heater, let's try to understand its strengths and weaknesses.
Appointment, repair and replacement of heater components PLANAR-4D-1224;
Heaters PLANAR-4D-12; PLANAR-4D-24 differ from each other in software and air blower.
1. Checking and replacing the glow plug.
The glow plug ignites the fuel mixture when the heater is started. The performance check and replacement of the spark plug should be carried out as follows:
- remove the heater from the vehicle;
- unscrew the screws securing the candle cap and remove the protective cap of the candle.
- unscrew the screws securing the covers, remove the covers
- disconnect the connectors pos. 2 (see fig. 4);
- unscrew the candle pos. 1 and remove carbon deposits from it;
- check the insulation resistance of the candle body with a voltage of 100 V according to fig. 5. Insulation resistance must be at least 10 megohms.
Rice. 5 - Scheme of checking a candle
- connect the candle to a direct current source with a voltage of 12-0,3 In and through
Measure the consumed current for 25 sec.
The consumed current should be no more than (3.5 ± 0.5) A, while the heating element of the candle heats up to a bright red color, starting to glow from the tip of the candle. Test time no more than 120 sec. The time between switching on is not less than 180 sec.
The spark plug must be replaced if it does not meet the listed requirements.
When replacing the spark plug, the installation is carried out in the reverse order, making sure that the sealing washer is installed, as shown in
2 Dismantling and replacing the spark plug mesh
The grid is designed to evenly supply fuel to the combustion chamber.
When replacing or inspecting the spark plug, the screen should also be checked for carbon deposits or clogging. If carbon deposits are found, the mesh must be replaced. Install the mesh in the combustion chamber connection in accordance with Figure 6 as far as it will go, while the hole must first be cleaned? 2.8 mm from possible clogging.
Figure 6- Scheme of installing a plug and a grid in the combustion chamber
Attention !! The mesh should be installed with an interference fit until it stops. If the mesh is installed not all the way to the end, the heater may fail when starting.
3 Dismantling and replacing the overheating sensor .
The overheating sensor pos. 1 see fig. 7 is used to monitor the heating temperature of the heat exchanger. When the heat exchanger reaches a temperature above 250 ° C, the overheating sensor opens the electrical circuit, and the heater is automatically turned off. The reason for the replacement may be the shutdown of the heater when the heat exchanger temperature is below 250 ° C or for the reasons indicated in table. 4.
To avoid an error when assessing the performance of the overheating sensor, it is necessary to replace it with a serviceable overheating sensor. If with a new
sensor, the cause of the heater malfunction will be eliminated, then the removed sensor is considered inoperative and must be dismantled.
Dismantle the overheating sensor as follows:
- remove the heater from the vehicle;
- unscrew the screws securing the candle cap and remove the protective cap of the candle.
Unscrew the screws securing the casing, remove the casing pos. 4 (see Figure 2).
- disconnect the contacts of the wires from the overheating sensor and unscrew the screws securing the sensor; remove the overheating sensor (see Fig. 7);
- check the cleanliness and reliability of the electrical contacts of the wires,
going from the electronic unit to the overheating sensor. If there is dirt or oil on the contacts, remove with clean chamois soaked in gasoline. Upon detection
burn on the working surface of the contacts, clean them with fine glass sandpaper No. 150 GOST 6456, wipe with gasoline and tighten the contacts.
When replacing the overheating sensor, install in the reverse order.
Figure 7 - The main units and parts of the heater
4 Checking, dismantling and replacing the flame indicator .
The flame detector is used to detect the presence of a flame in the combustion chamber. It is a tube with a built-in thermocouple with two leads.
Check the flame indicator as follows:
- remove the heater from the vehicle;
- unscrew the screws securing the candle cap and remove the protective cap of the candle.
- unscrew the screws securing the covers, remove the covers, pos. 3 and 4 (see Fig. 2).

- unscrew the indicator from the combustion chamber housing pos. 4 (see fig. 4).
- check the insulation resistance between the terminals and the indicator case.
The resistance must be at least 20 megohms.
- check the resistance between the leads of the flame indicator. The resistance should be between 3-10 ohms.
Measurements should be carried out at normal temperature and humidity. If the indicator is not
serviceable, then it must be replaced.
When replacing the flame indicator, installation is carried out in the reverse order.
5 Purpose, dismantling and replacement of the air blower.
The air blower consists of an electric motor with a volute attached, on the shaft of which a fan is installed on one side, and an impeller on the volute side.
An air blower supplies air to the combustion chamber to ensure combustion,
purges the combustion chamber before the beginning and end of the combustion process in order to cool and remove the remaining fuel and moisture,
creates an air flow, which, passing through the radiators of the heat exchanger during the operation of the heater, heats up, and also changes the air flow due to
changes in the speed of the electric motor.
If the electric motor or the impeller fails (the impeller touches the volute), the air blower must be replaced with a new one.
Dismantle the air blower as follows:
- remove the heater from the vehicle;
- unscrew the screws securing the candle cap and remove the protective cap of the candle.
- unscrew the screws securing the covers, remove the covers, pos. 3 and 4 (see Fig. 2).
- disconnect the contacts of the wires of the electric motor from the connectors of the control unit;
- unscrew the screws securing the control unit;
- remove the spring washer pos. 33, the fan pos. 25 and the shell
- unscrew the screws securing the air blower to the adapter;
- remove the air blower.
When replacing the air blower, installation is carried out in the reverse order.
Fig. 10 - Air blower
6 Dismantling and replacing the control unit .
The control unit provides control of the heater in conjunction with the control panel.
The control unit performs the following functions:
a) initial diagnostics (serviceability check) of the heater units at startup;
b) diagnostics of the heater units during the entire operation;
- in case of loss of performance of one of the monitored nodes;
- when the parameters go beyond the permissible limits (temperature, voltage);
- when a flame is blown out in the combustion chamber.
When determining the malfunction of the control unit, it is necessary to make sure that all the components of the air heater are in good working order, and then replace
control unit, and if the air heater with a new control unit is operational, then the removed one is considered inoperative and must be replaced.
Dismantle the control unit in the sequence specified in subsection 5.5. When replacing the control unit, installation is carried out in the reverse order.
– Purpose, dismantling and replacement of the combustion chamber .
An evaporative combustion chamber (see Fig. 11) is designed to create and burn an air-fuel mixture.
A sign of failure of the combustion chamber is the failure to start the heater.
(with all other serviceable heater elements), increased CO content (more than 1%), temperature rise (more than 500 ° C) in the exhaust gases, burnout or loss of tightness by the combustion chamber body.
If the combustion chamber fails, it must be replaced.
Dismantle the combustion chamber as follows:
- remove the heater from the vehicle;
- unscrew the screws securing the candle cap and remove the protective cap of the candle.
- unscrew the screws securing the covers, remove the covers, pos. 3 and 4 (see Fig. 2).
- disconnect the connectors pos. 2 (see fig. 4);
- unscrew the candle pos. 1 (see figure 4);
- disconnect the contacts of the wires from the overheating sensor;
- disconnect the contacts of the wires of the flame indicator from the connector of the control unit;
- unscrew the screws securing the air blower to the adapter and remove it
from the adapter pos. 5 (see fig. 4);
- unscrew the screws (inside the adapter housing) fastening the adapter to the heat exchanger and remove the adapter;
- unscrew the screws securing the combustion chamber to the heat exchanger.
- when replacing the combustion chamber, it is necessary to assess the condition of the heat exchanger, see chap.
- the installation of the camera is carried out in the reverse order; in this case, it is necessary to replace parts 813 and 817 (for gaskets, see Fig. 2).
8 Purpose, dismantling and replacement of the heat exchanger
Heat exchanger pos. 1 (Fig. 12) is designed to transfer heat from hot gases formed from the combustion of the air-fuel mixture to radiators pos. 4 (Fig. 12) which, in turn, transfer heat to the air.
Malfunctions that can occur during the operation of the heat exchanger are loss of thermal conductivity due to the deposition of products
combustion of diesel fuel on the inner walls and fins of the heat exchanger, as well as burnout as a result of non-observance of the rules for operating the heater and, as a result, loss of tightness and release of combustion products into the heated
premises. Dismantle the heat exchanger in the sequence indicated in subsection 5.7, while in order to remove the radiators it is necessary to remove the clamps pos. 5 (see fig 12). It is not allowed to remove the radiators without removing the clamps.
After dismantling, clean the inside of the heat exchanger from carbon deposits and
soot. When replacing the heat exchanger, the installation is carried out in the reverse order; in this case, it is necessary to replace parts 813 and 817 (gaskets) (see Fig. 2). It is not allowed to move the radiators fixed with clamps along the heat exchanger in order to avoid nadirs on its surface.
Purpose, determination of malfunction, dismantling and replacement of the fuel pump.
The fuel pump (Fig. 13) serves for the metered supply of fuel to the combustion chamber.
The main parameters of the fuel pump:
- rated supply voltage - 12 V or 24 V (depending on the heater);
a) 4.5 - 5 ohms (for 12 V fuel pump);
b) 14.5-16 ohms (for 24V fuel pump).
- Possible types of malfunctions of the fuel pump as part of the heater:
a) during the heater start-up, fuel does not flow to the heater fuel pipe and the characteristic knock in the fuel pump is not heard;
b) fuel enters the heater fuel pipe with a delay
(2 start attempts have been exhausted).
5.9.2 Eliminate faults and determine the performance of the fuel pump as follows:
- before eliminating possible malfunctions, it is necessary to check the presence and quality of fuel in the tank;
- make sure that the wiring and connectors are in good condition;
- make sure that the fuel pump works when the heater is turned on and that a characteristic knock is heard from the movement of the piston inside the pump.
It is allowed to remove the fuel pump and shake it (if the characteristic knock is not heard, then the piston may stick inside the pump due to long-term storage or due to failure to perform preventive
measures according to the Operation Manual);
- make sure that the fuel line is tight all the way to the fuel pump and from the fuel pump to the heater;
- check the tightness of the connection between the fuel pump housing and
inlet fitting. Check with air at a pressure not exceeding
1kgf / cm 2. Apply pressure from the inlet and outlet simultaneously. If the connection is not tight, then install the union on a sealant.
If all of the above malfunctions are eliminated, then it is necessary to check the fuel pump for performance. Install the fuel pump in the fuel supply system to the heater heater and the pumping device
Fill the fuel line up to the heater with fuel. Remove the fuel line from the heater fuel tube and place it in a 50-100 ml beaker with a graduation of not more than 1 ml to measure its performance.
Start the heater and check how much fuel the fuel pump will pump into the beaker in two automatic attempts to start the heater. Should the amount of fuel in the beaker be 5.5? 6 ml. If the amount of fuel
is less or more than 5.5 - 6 ml, then replace the fuel pump.
Before doing self-repair, I recommend assessing the situation as a whole. I mean, I will get acquainted with the accompanying documentation for the heaters, which I have collected for you in one place, I think it will be quite sufficient, and also in our descriptions of the problems that have arisen with your heater, we will try to repair it. The success of this repair is of course now in your hands. But first, assess the situation calmly and reasonably, it takes time, and time is money. At my discretion, everyone should do what he can do well, and receive moral and material satisfaction from this.
Do you have a HEATER of the passenger compartment, or a prestarting liquid heater?
To be honest, there is not much difference in their principle of operation. Some heat the air and accelerate through the cabin creating coziness and comfort, others heat the antifreeze and drive it through the engine cooling system, heating it, allowing it to facilitate starting in winter with the ability to warm up the interior.
The difference in them is only in the efficiency of energy consumption, electrical and fuel.
Heaters are designed for economical operation and for a relatively long time, here and the thermal power is smaller and the pump and fan for consumers. The prestart has a different main task - it is to warm up the engine as quickly as possible before starting, but of course not at any cost. What's the point of having a hot engine with a discharged battery. But the order of electricity consumption is hundreds of times less than turning a cold engine with a starter.
Table troubleshooting for the autonomous heater planar 4dm and 44d
Traditionally, a house, an apartment, an extension, or, in extreme cases, a garage, if it acts as a part-time workshop, needs heating. Both industrial and public premises and even open areas are heated, for example, with the help of infrared heaters.
But in the conditions of a harsh winter, car interiors also need heating: trucks, buses, and the like.
An installation that heats the cab or the driver's workplace with the help of streams of warm air is called an air heater.The design includes a heating element, a pump for supplying diesel fuel, control gear and wires for connecting the elements. The devices are produced by the Russian plant "Planar" (Samara) and are characterized by an affordable price with high efficiency, as evidenced by reviews. The photo shows a car heating installation.
The principle of operation of the Planar air heater is as follows: the fuel mixture is pumped into the combustion chamber. The heat from the combustion is transferred to the heat exchanger. The latter is blown by a stream of air, and then the heated air is supplied to the driver's cab. Combustion products are removed from the car interior, therefore, it is prohibited to use the Planar heater indoors - garage, workshop.
The fuel mixture for the device is diesel fuel obtained from the tank. The heater works in autonomous mode, regardless of the state of the engine.
Each time the heater is turned on, a preliminary test of the overheating sensor, pump status, burner indicator and electrical circuits is carried out. If there is a deviation in the state of the elements according to the instructions, ignition will not be initiated. If the test is successful, the combustion chamber is pre-purged - air is removed from the passenger compartment, the candle is lit, and then a mixture of fuel and combustion air is supplied. Upon reaching a normal stable combustion, the candle turns off.
When disconnected, the supply of the fuel mixture is interrupted, the burner is extinguished and the combustion chamber is purged.
The temperature is automatically adjusted according to the set value: from 15 to 30 degrees. When the temperature in the passenger compartment reaches the set value, the device switches to a mode with less heat transfer. If the difference between the parameters is large, the device can activate the ventilation mode, which helps to cool the workplace. When the air temperature drops, the Planar autonomous heater switches to a more active mode. Optionally, the device can be equipped with a remote temperature sensor, which is located in the cab
Installation of the unit is carried out only by specialists.
The device works in stand-alone mode - the engine can be turned off.
Will report low fuel consumption. The latter is fed into the heater from the tank.
The combustion products are discharged from the vehicle interior, providing a clean atmosphere inside.
The device is compact and lightweight - up to 12 kg, depending on the model. At the same time, the cab is heated literally in a matter of minutes. The photo shows a sample.
Affordable cost.
The disadvantages include some limited use - the installation cannot be placed in places where dust accumulates or the accumulation of vapors of flammable substances is possible, and the presence of a battery is also mandatory.
The Planar heater is equipped with several security systems that ensure stable operation of the device and emergency shutdown in case of abnormal operation.
If the startup attempt fails, a second attempt is made by default. If the start-up is still not possible, the device switches off.
In the event of a burner malfunction, the device switches off immediately.
An automatic shutdown is also performed when the heat exchanger overheats. When the current falls or surges, the unit shuts down.
All of the above events are reflected on the control panel by a blinking LED - red or orange, in a specific mode. The instruction contains a decryption of signals, which allows you to quickly establish the cause of the inoperative state, as evidenced by user reviews. The photo shows the control panel.
You can extend the service life of an autonomous heater and significantly reduce repair costs by observing the rules of use recommended in the instructions.
Fuel - It is known that the efficiency of an engine depends on the ambient temperature.It is also recommended to observe certain conditions for the Planar heater. So, at temperatures up to -5 C, diesel fuel 3-0.2 is used, at values from -5 to -20 C, it is advisable to use a mixture of gasoline and diesel fuel, and at lower temperatures - fuel grade A-0.4.
It is recommended to turn on the heater for 5-10 minutes once a month, even when there is no need to heat the passenger compartment. Thus, the appearance of film deposits in the fuel pump is preceded.
The device must not be switched off before the end of the purge phase. Disconnection is possible at any other moment.
Check the battery charge level. If the car is not used for a long time, the Planar heater must be disconnected from the battery.
Do not connect the heater to the electrical circuit of the machine while the engine is running. The device is powered only from the storage battery, regardless of the mass of the vehicle.
Switch off the device when refueling the vehicle.
It is recommended to entrust the repair of the device to specialists. However, judging by the reviews, you can cope with simple malfunctions not related to the burner and damage to electrical parts. The instructions supplied with the device describe in detail the most likely ones.
Quite often, if the recommendations for switching to winter fuel are not followed, the fuel filter becomes waxed. As a result, the Planar device does not turn on. In this case, you should first replace the fuel for the appropriate weather conditions, and check the operation of the fuel intake. If, after cleaning its filter, the Planar heater still does not work, dismantle the fuel supply pump, and, by unscrewing the union, remove the filter. The element is washed in gasoline and blown with compressed air, and then installed in place. At the end of the repair, the fitting should be fixed with sealant. The video shows the filter cleaning process in more detail.

If you need to repair a part separately, then before removing and bringing it to repair autonomous heater to the service center, you need to write off the error code, but it is better to send a photo in advance.To clarify the error code on mechanical models 4DM you need to count the number of flashes of the LED, and on electronic 4D, rewrite the numbers displayed on the remote control.
Having carried out diagnostics and assuming a malfunction, drivers often decide to repair the autonomous system on their own. However, it is difficult for a layman to understand all the nuances and to carry out the adjustment of the unit without errors. One of the features of the built-in diagnostics is the display of a faulty circuit without specifying a specific part of the faulty one. In some cases, several units may break, which will complicate the identification of the malfunction and the repair of the heater. Only qualified craftsmen will be able to quickly cope with this task.
Accumulated carbon deposits on the evaporator screen, melted contacts and candles, combustion products on other parts can cause the control unit to fail. As a result Planar (Planar) will give incorrect codes for Planar 44D and other models. In this case, only specialists can identify the cause of the breakdown, and do-it-yourself repairs can lead to disastrous consequences or an increase in the cost of the entire process.
