Hotel air conditioning fault code

Hotel air-conditioning fault code refers to all kinds of faults in the operation of hotel air-conditioning equipment, and reflects the specific situation of faults through relevant codes or information prompts. The following are common fault codes of hotel air conditioners:

1.E 1: Communication failure of indoor and outdoor units of air conditioner, which may be cable connection failure or damage of indoor and outdoor temperature sensors.

2.E2: Fan failure, possibly motor failure or drive board failure.

3.E3: Indoor temperature sensor failure, which may be sensor damage or circuit board failure.

4.E4: High-voltage protection, which may be the fault of refrigeration system or circuit board.

5.E5: under-voltage protection, which may be caused by fluorine leakage in the refrigeration system or compressor failure.

6.E6: Communication failure of outdoor unit, which may be cable connection failure or outdoor temperature sensor damage.

7.E7: indoor fan circuit failure, which may be circuit board failure or fan motor failure.

8.E8: Communication failure of indoor and outdoor units, which may be cable connection failure or damage of indoor and outdoor temperature sensors.

9.P0: Condenser temperature protection, which may be a condenser fault or a refrigeration system fault.

10.P 1: protection of refrigeration capacity, which may be due to insufficient refrigeration system or secondary system failure.

The above are common fault codes of hotel air conditioners. When the air conditioner fails, it needs to be found and handled in time to avoid affecting the guests. At the same time, the hotel air-conditioning equipment needs regular maintenance to reduce the failure rate.
