What's wrong with the compressor doesn't work when the excavator air conditioner is turned on?


Compressor does not work generally is no refrigerant, and there are problems with the line or compressor.


Starting from the starting capacitor starter overload protection compressor, line, control these checks.


The compressor is protected from high temperature and high temperature overload, and after the temperature drops, it automatically returns to start operation. After operation, the temperature rises again, and once again overload protection, it keeps circulating.


The possible causes and elimination of high pressure are:


The condenser has a bad heat dissipation. Check whether the cooling fan is rotating, whether the condenser tube has dirt or dirt, and clean the condenser.


The refrigerant is too much. Increasing compressor load leads to high pressure and proper reduction of refrigeration dosage.


The pipeline system is blocked. Refer to the pressure gauge to judge and exclude the system.


Dirt in evaporator or filter net is fouling. The air flow becomes smaller, the pressure and temperature of the system are constant, and the evaporator or filter screen is cleaned.


The compressor start capacitor is burned down. It is necessary to replace the capacitor.


The starting coil of the compressor is burnt out and can not start operation, which causes the starting current to be too large and the protection device to jump off. The only way to replace the compressor.
