This is the outdoor unit of the air conditioner. The fan blades spin but do not operate.

This is the outdoor unit of the air conditioner. The fan blades spin but do not operate.

The possible cause is the compressor protection device tripping.

The compressor overload protection tripping means that the system high pressure is too high or the overheat current is too large.

Causes and troubleshooting of excessive pressure and overheating:

1. Too much refrigerant. Appropriately reduce the amount of refrigerant.

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

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

4. The evaporator or filter is dusty and limescale. The air flow becomes smaller and the system pressure and temperature become unstable. Clean the evaporator or filter.

5. Fluoride deficiency is also possible. In case of lack of fluoride, the temperaturecompressor exhaust will overheat, causing the load overheat protection switch to trip.

The circuit problems are:

1. The circuit board is defective.

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

3. Power wiring is loose and contact is poor.

4. The compressor start capacitor or start coil is blown.

Insufficient information can only be analyzed in this way. There are many other possibilities

It is recommended to find a maintenance professional to check.

I hope this helps you, don't hesitate to adopt it if you are satisfied. Thank you...
