What to do if the refrigerator engine doesn't work

Check whether the power socket is charged first to ensure that the plug is in good contact. Question. If there is a problem with the control circuit or the compressor itself, it is recommended to ask professional maintenance personnel to check and repair. Science popularization of relevant knowledge: If the refrigerator compressor does not work, the ambient temperature may be too low.

/Suggested solution: If it is found that the components of the compressor have been burned after professional inspection, it is necessary to repair and replace the components in time after disassembling the refrigerator, so that the compressor can return to normal operation, so as to solve the problem of not starting after power-on.

In this case, you need to find a special person to be responsible. Damage to the components of the refrigerator will often cause the engine in the refrigerator to not work or other effects. This requires a special person to repair it to ensure that there is no problem with the components that the main work of the refrigerator. If there is a problem, you can replace or replace a new refrigerator.

What is the reason why the refrigerator engine flashes when it rings?

1. It may be because the temperature of the refrigerator is too high. When the temperature of the refrigerator exceeds the set temperature, the spring sheet on the thermostat will automatically bounce up to form a loop. In this case, it will also make a noise. Unplug the power supply, wait for the temperature to drop, and then put it into use again.

2. When the refrigerator starts, there should be a sound when the temperature control switch jumps to the connected position. In addition, the sound will be slightly louder when the compressor starts, which is normal. Don't worry.

3. If there is a banging sound in the refrigerator, and the sound is made in the running electric refrigerator compressor, which is the sound made by the spring in the compressor being broken or displaced, it should be repaired in time.

4. Reason 1: The temperature in the refrigerator is too high, resulting in fluorine leakage in the refrigeration system, that is, the refrigerator is not cooling because there is no refrigerant.Solution: Find a repairman, re-weld the pipe, and take the time to re-add refrigerant. Reason 2: Frosting in the evaporator.

5. The floor of the refrigerator is not flat or the placement is unstable, which is a common reason for the noise of the refrigerator. The huge sound of "boom", "giggle" and "tata", accompanied by obvious vibrations. When this kind of sound appears, users should pay special attention and should immediately find after-sales service for door-to-door repair.

The refrigerator engine is hot, but it is not cooled

1. The reason why the refrigerator does not cool: If it is not cool, there may be a problem with the refrigerator compressor. The compressor can start. When removing the return pipe and blocking the outlet with your finger, check how high the pressure is. If it is too low, then there is a problem with the compressor. The compressor cannot start. Check whether the refrigerator power supply is plugged in.

2. If the compressor can start normally, it is necessary to consider whether the refrigerant has been used up or the refrigerant has been leaked. It may be that the exhaust pressure of the compressor is insufficient, which will cause the compressor to fail.

3. The refrigerator does not cool, but the reasons why the compressor heats up are as follows: the high-pressure output buffer tube in the compressor is broken, or the screw fixing the tube is loose, resulting in the high-pressure pipe not exhausting and the low-pressure pipe not inhaling, so although the compressor is running, it does not cool. The solution to this situation is to cut the shell, replace the buffer tube, or tighten the screw.

4. There is a blockage in the circulation of the refrigeration system, resulting in the inability of the refrigerant to enter the evaporator to evaporate and absorb heat, resulting in the problem of heat when the refrigerator does not cool. It may also be caused by improper adjustment of the refrigerator temperature controller, or uneven internal convection and loose sealing of the refrigerator door.

5. It is normal for the compressor of the refrigerator to heat up. The reasons for the poor refrigeration effect are: the loss of refrigerant caused by the leakage of the refrigerator refrigeration system, the need to suppress the refrigeration system of the refrigerator, find the leakage point, make up for the leakage point, and fill the refrigerant in the air.
