What are the methods of fault maintenance of air-conditioning compressor?

If there is a problem in the motor part of the compressor, the thermal protector fails, and the suction and exhaust valves of the compressor are improperly closed, the method of replacing parts can be adopted.

The compressor shaft is locked and the cylinder is stuck;

1, tapping method:

After starting, knock the lower half of the compressor with a wooden hammer to make the stuck parts inside the compressor vibrate.

2, high pressure start method:

A voltage regulator can be used to boost the supply voltage and then start it.

3, capacitor startup method:

You can use a capacitor with large capacitance to access the circuit to start.

4, pressure relief method:

After all refrigerant is discharged, start the system.
