Haier HPR09XC7 Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrost cycle if necessary, to get rid of the frost that collects on the outdoor unit. It looks to a specific sensor located near the condenser to agree when the defrost cycle should begin.
Major signs the AC defrost sensor board should need replacing
- The primary control board may show an error signal produced when the defrost control board fails to receive a signal
- Defrosting refuses to run especially when there is a rather large amount of frost on the external unit
- The HVAC system could not operate for the simple fact of the fact that there is too much frost
