What if Fiat's air conditioner stops working at the weekend?

The most likely cause is the tripping of the compressor protection device.

The compressor overload protection will trip, which means that the system high voltage or overheating current is too high.

Causes and elimination of high pressure, high temperature and overheating;

1, too much refrigerant. Reduce the amount of refrigerant appropriately.

2. Poor heat dissipation. Check the condenser tube for dirt and clean the condenser.

The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate and reprocess the system.

4. Evaporator or filter screen accumulates dust and scale. The air flow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter screen is cleaned.

5. Fluorine deficiency is also possible. When fluorine is lacking, the exhaust temperature of the compressor will overheat, which will trip the overheat load protection switch.

The problem with the circuit is:

1, control circuit board failure.

2. The temperature sensor is overloaded and the information is wrong.

3. Loose power cord and poor contact.

4. The starting capacitor or compressor starting coil is burnt out.

There is not enough information, so we can only analyze it in this way, and there are many other possibilities.

It is recommended to find a professional maintenance person to check it.

I hope I can help you. If you are satisfied, please accept it. thank you ...
