Midea R32 M thermal Arctic Mono fault P3

What it means

Error code 23. Compressor current protection detected by user interface and refrigerant system main PCB.

Likely causes

1. Compressor current exceeds Currentmax for the specific model
2. Compressor mechanical fault
3. Electrical supply issue
4. Excessive compressor load
5. Abnormally high compressor current Compressor mechanical failure, high system pressure, electrical supply issues, motor winding fault Power supply abnormal, poor condenser heat exchange, high pressure side blockage, inverter module damaged, or compressor damaged
6. Power supply equipment is abnormal
7. Condenser heat exchange is poor
8. High pressure side blockage
9. Inverter module damaged
10. Compressor damaged
11. Main PCB damaged
12. Electrical fault causing excessive compressor current draw
13. High pressure side is blocked, caused by crushed or bent pipe or blocked EXV
14. Inverter module has short-circuited
15. Compressor has malfunctioned
16. Outdoor main PCB fault
17. Compressor overcurrent
18. Compressor fault
19. Discharge temperature exceeding 105°C indicating high compressor load or high ambient/system conditions
20. Compressor current exceeding Currentmax threshold

Where to start

1. Measure compressor current draw
2. Compare to model-specific Currentmax value
3. Check compressor electrical connections
