Midea R32 M thermal Arctic Mono fault H5
Room temperature sensor error
Heat pumpWhat it means
Error code 44. Room temperature sensor (Sensor Ta) fault detected by user interface and hydronic system main PCB.
Likely causes
- Temperature sensor not connected properly or has malfunctioned. Damaged hydronic system main PCB.
- Sensor Ta circuit fault
- Sensor damage or disconnection
Where to start
- Identify sensor type based on fault code
- Locate corresponding port on refrigerant system main PCB for that model
- Check connection at identified port
