In detail: do-it-yourself scarlet oil cooler repair from a real master for the site my.housecope.com.
A breakdown of an oil cooler can happen unexpectedly and at a very inopportune moment. If oil drips appear on the case, the device should be disconnected from the network immediately and think about buying a new heat source. In case of other malfunctions, the device can be brought back to life with the help of a wizard or independently. It is recommended to take on the repair of an oil heater with your own hands only if you have basic knowledge in the field of electrical engineering, while not forgetting about observing safety precautions.
Any repair begins with diagnostics. It is important to correctly determine the cause of the failure and calculate the defective part.
Do not be alarmed if the heat source starts to crackle immediately after switching on. As a rule, this happens during the heating of the mineral oil inside. Crackling is considered normal and does not affect the performance of the appliance. Sometimes moving the radiator to a perfectly flat place helps to reduce the noise.
If the heater stops turning on, the first step is to exclude a breakdown in the outlet and connect the device to another power source. The most common breakdown in this case is a loose contact, in second place is a malfunction of the plug, and in third place is damage and breaks in the cord.
If the heater shows signs of operation (the indicators are on, the fans turn on), but does not heat up, the cause should be looked for in the thermostat. This spare part is easy to buy and replace with your own hands.
A cold case may also indicate that the heating element is out of operation - this is a rather serious reason and it is not recommended to eliminate it on your own.
If the device does not turn off after heating to the set temperature, this may signal a thermostat malfunction - such work becomes not only uncomfortable and dangerous, but also uneconomical in terms of energy consumption.

The oil cooler is a non-separable design, so you cannot break the hermetically sealed case of the device when trying to replace a faulty heating element. Self-repair of the oil heater is possible only at the level of the cord, plug and control unit. To the delight of home craftsmen, the most frequent breakdowns occur in these places. In order not to get confused in spare parts, it is recommended to group all fasteners and parts and take step-by-step photos during operation - this will make it easier to assemble the device in reverse order.
First of all, the cord is examined and carefully probed, trying to detect creases. If the cord has been bent for a long time, it is most likely that a defect has formed in this area. The plug, if its design allows, is disassembled and the integrity of the contacts is checked. Most often, the problem is hidden at the point of connection of the pins of the plug with the ends of the current-carrying conductors of the cord.
If there are no visible signs of failure on the cord and plug, you should use a special device - an ohmmeter and "ring" the cable. It is also necessary to revise the connection of the electrical wire to the terminals of the power supply and check the condition of the unit, after removing the decorative cover of the front panel. The found carbon deposits are removed by thoroughly cleaning the elements. Loose fasteners are gently tightened, restoring contacts. If you have a new power cord with an outlet in stock, you can see the old cable with it.
In order not to disassemble the power supply a second time, it is recommended to immediately inspect the thermostat.To gain access to this module, you need to slightly raise the anchor of the device and inspect the contacts. Darkening indicates that there was a short circuit in the appliance. Its consequences can be easily eliminated by cleaning the electrical contacts with sandpaper and treating with alcohol. Small debris formed during the cleaning process is removed from the unit with a vacuum cleaner.
Damaged tires are also subject to replacement - new blanks are easy to cut from a sheet of brass of the same thickness, using the old parts as a template. The holes for the fasteners are drilled with a drill. The temperature controller has bimetallic plates, which must be replaced in the event of a breakdown. To remove the plate, disassemble the thermostat, carefully and consistently unscrewing all the nuts.
These polar problems have one root - a malfunctioning thermostat. To find the cause, an important module is disassembled and carefully examined. The safest thing is to replace this part by looking for spare parts for oil heaters on the market. You can try to adjust the knocked-down settings yourself by setting the armature travel within 1.5-2.5 mm. Ideally, it should move abruptly from the magnet to the stop.
After completing the repair, the device is assembled and connected to the network. The absence of the expected result is a reason to contact a specialist or an eloquent hint that it is time to purchase a new electric heater. Replacing the heating element at home, as well as welding and soldering a damaged case is strongly discouraged.

Oil radiators are remarkable in that they are almost a complete analogue of a central heating battery. Do not burn indoor air. Some of the heat is distributed as radiant infrared energy. Therefore, they are very popular.
Today we will try to repair another heating device with our own hands.
Take one of the radiators for example Scarlett SC-1151. Structurally, they are all about the same.
The tool that we need for work: an ordinary Phillips screwdriver and a multimeter to check.
Dismantling the oil cooler is easy.
We unscrew the screw that secures the decorative front cover. Carefully set aside.
As usual, the conclusions of the service center say: “does not heat up”, “does not turn on”. First of all, let's check the performance of the heating element.
In our case, to adjust the power, it is divided into two branches.
Let's check the integrity of the thermal fuse, which is in the circuit in front of the heating element. For clarity, we stripped the insulation.
Let's check the thermal relay, which should turn off the heating element when the radiator overheats. The tester shows an open circuit.
KSD301 80 deg. The price in the online store is 30-50 rubles.
Please note that one contact has changed color due to overheating.
For the sake of sports interest, we disassembled the thermal relay. The burned contacts are clearly visible in the picture. Such a relay must be replaced, especially since its case is cracked.
Replacing the relay and assembling the "oiler" takes fifteen minutes.
Oil-fired electric heaters have simple design, therefore, usually during their operation, there are no special difficulties.
In most cases, they fail, having worked more than one warranty period.
However, even the simplicity of the design sometimes cannot save the oil heater from breakdown, which usually happens at the very inappropriate moment.
Difficulties in troubleshooting can only be caused by oil leak, the appearance of which is easy to detect upon visual inspection of the device.Oil leaks appearing on the heater body indicate that the device must be turned off urgently, and then take care of purchasing a new heating device.
Some craftsmen are able to bring the oil heater back to life even after such a malfunction occurs, but this work quite difficultwhich takes a lot of time. Such repairs are extremely rare.
To repair other damage, usually contact a specialisthowever, with basic knowledge of electrical engineering, it is quite possible to solve the problem on your own.
Experts believe that the correct fault definition makes the repair of the device halfway done. Therefore, the first stage in the repair of an oil heater is always the diagnosis of the device. In order to find a device malfunction, you need to know how it works, what parts are included in its design.
In appearance, an oil heater most often resembles regular battery heating, however, this device is sealed and its interior is filled with oil.
At the bottom of the container heating element inserted... A thermal fuse is located near the heating element, which serves to turn off the heater when the temperature of its body rises excessively.
Thermal relay usually located in the upper part of the body, not in contact with it. A switch is placed close to the relay. If it is present, there is no need to remove the plug from the socket to turn off the heater.
The simplest oil heater circuit looks like that:
When the circuit breaker is closed, after turning on the plug of the electrical appliance, the heating element immersed in oil begins to heat up. The start of the device is signaled by a light.
An adjustable thermostat determines the maximum temperature after which The heating element will turn off... It will switch back to heating mode after the device cools down to the set temperature.
Thermostat adjustment occurs with a bimetallic plate inside it. The position sensor is designed to break the electrical circuit when the heater rolls over.
For better control the operation of the device is equipped with two heating elements. In this case, two switches are installed on the body. With their help, the heating power is regulated. During adjustment, one of the heating elements can be switched off.
The schematic diagram of an oil heater with a fan practically differs little from a conventional heating device. Its main difference is that in the presence of a fan, the heating elements impossible to turn onif the fan does not work for some reason. Such a heater scheme excludes damage to heating elements from overheating.
If a heater was working properly yesterday, today stops heating, then there is no need to immediately run to the workshop, or to the store for a new heating device.
Many malfunctions are quite possible fix it yourselfhaving basic skills in electrical appliance repair.
An exception may be faulty heating element, most often tightly sealed in the heater body. It is quite possible to remove it, but it will no longer be possible to install it in place. Even if the heater is equipped with a removable heating element, it will be difficult to achieve the tightness of the device when replacing it.
Usually, malfunctions that occur when a heater breaks down appear in more accessible places. The most vulnerable point the device is a cord, so its integrity should be checked first. If the design of the plug allows it to be disassembled, then you need to check the junction of the cord veins with the pins of the plug.
If the plug is working properly the next step should be to check the condition of the cord itself, as well as the place of its connection with the heater's power supply. For this, the decorative cover of the device panel is removed and the tester checks the integrity of the cord.If it is damaged, the cable is replaced with a new one.
If the cable turns out to be working, then the malfunction may be hidden in the state of the contacts of the power supply. Contacts can be caked and loosened.
In this case, the contacts are cleaned of carbon deposits. sandpaper, and loose contacts are gently tightened.
The thermostat is located in the same place. If darkening is visible on its contacts, then they also need to be cleaned. The thermostat may be defective bimetallic plates... If damage is found, the thermostat is carefully disassembled, and the plates are replaced with new ones.
If the oil cooler belongs to the category energy saving, then in its design there is a thermostat that enables the device to be turned on and off at the given parameters.
Excessive heat heater, or low temperature, it must also be inspected. If a malfunction is detected, this part is changed to a new thermostat with similar parameters.
If there is a fan in the design of an oil heater, it is also need to check... In this case, not only the contacts of the device are checked, but also the integrity of the winding of its motor. It is possible that it may need to be replaced.
After completing the above checks and eliminating the noticed faults, the heater is assembled and then connected to the network. If the heating device still doesn't work, you will have to seek the advice of a specialist.
Most likelythat he would advise you to buy a new heater. Some repairs can be so expensive that it's easier to head to the store.
