Why Is the Air Conditioner Flashing Yellow and the Compressor Not Working?
2024-10-10
The reason may be the phenomenon of the compressor protection device tripping. When the compressor overload protection trips, it indicates that the system high-pressure is too high or the overheating current is too large. Causes and troubleshooting of high pressure and overheating:
- Excessive refrigerant. Appropriate reduction of refrigerant charge.
- Poor heat dissipation. Check whether the condenser tube is dirty and clean the condenser.
- Blockage in the pipeline system. Judging and troubleshooting according to the pressure gauge, and reprocessing the system.
- Dust and scale accumulate on the evaporator or filter. The air flow becomes smaller, and the system pressure and temperature are unbalanced. Clean the evaporator or filter.
- Lack of fluorine is also possible.
When there is a lack of fluorine, the exhaust temperature of the compressor will be overheated, causing the overheating load protection switch to trip.
Problems in the circuit are: - Fault of the control circuit board.
- Overload of the temperature sensor and incorrect information.
- Loose power connection and poor contact.
- The starting capacitor or the compressor starting coil is burned out.
