What is the reason why the compressor of automobile air conditioner doesn't work? What are the common problems?

The reasons why the automobile compressor does not work are: 1, and the internal wear of the compressor is serious, which leads to the compressor not working normally. 2. The belt slips, resulting in the compressor not working. 3. Refrigerant leakage leads to insufficient system pressure, which triggers the compressor protection switch, resulting in the compressor not working. 4, automobile air conditioning temperature sensor failure, resulting in the compressor does not work, etc.

A detailed analysis of the reasons why the compressor of automobile air conditioner doesn't work;

1. The internal wear of the compressor is serious and it cannot work normally.

It is necessary to know that the compressor can play a vital role in the air conditioning system. Its main job is to compress and transport cold air, which leads to the compressor rotating at high speed for a long time, so this is one of the reasons why the compressor cannot work normally.

2. Check whether there is refrigerant leakage. If there is no cold air compression or transportation, it will definitely not work.

3. It is also common that the fault of the circuit system leads to the abnormal operation of the automobile air conditioning compressor. You can check whether the circuit is unblocked and check the solenoid valve of the temperature sensor.

Causes of non-operation of automobile air conditioning compressor and other fault reasons

(1) The plug of the control circuit of the air-conditioning compressor is loose, which leads to poor contact, so that the voltage supplied to the electromagnetic coil drops and the current is unstable, which leads to the electromagnetic clutch of the air-conditioning compressor being engaged and separated from time to time. Working for so long will definitely burn out the clutch and electromagnetic coil.

(2) The clearance of electromagnetic clutch of air-conditioning compressor is generally designed to be 0.35-0.50 mm If the clearance is less than the specified value, the clutch steel plate of air-conditioning compressor installed next to the engine will generate thermal expansion, resulting in too small clutch clearance, which makes the clutch unable to separate or slip after the air conditioner is turned off, and it is easy to burn out the electromagnetic coil, bearing, clutch and parts in the refrigeration system.
