jinxing air conditioning fault codes are divided into two types: common faults and rare faults.

Common fault code:

1. E: indicates that the indoor temperature sensor is faulty. Possible reasons include sensor damage, poor contact of sensor connection lines, etc.

2. E1: indicates communication failure of outdoor unit. It may be because the communication line between outdoor unit and indoor unit is blocked or damaged.

3. E2: indicates that the indoor air temperature sensor is faulty. It may be caused by damaged sensors or poor connection lines.

4. E3: indicates compressor overheating protection. It may be because the compressor works too long or the ambient temperature is too high, which leads to the compressor overheating.

5. E4: stands for refrigerant pressure protection. The refrigerant pressure may be abnormal due to insufficient refrigerant flow or air leakage in the system.

rare fault code:

1. F1: indicates indoor fan motor fault. It may be caused by damage or open circuit of fan motor.

2. F2: indicates outdoor fan motor failure. It may be caused by damage or open circuit of outdoor fan motor.

3. F3: indicates a power failure of the outdoor unit. It may be caused by poor contact of power line or failure of power module.

4. F4: indicates that the indoor air flow sensor is faulty. It may be caused by damaged sensors or poor connection lines.

5. F5: indicates communication failure of outdoor unit network port. It may be caused by damaged communication module of outdoor unit or poor line contact.

The above is the introduction of common and rare fault codes of Venus air conditioner. When the air conditioner fails, the problem should be eliminated in time according to the fault codes to avoid further loss.
