Friedrich P12B Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrosting phase in order to keep your outdoor unit from plugging up. It depends on a temperature sensor located in the outdoor unit to agree when to initiate the defrosting cycle.
Clues to watch for to know your outdoor defrost sensor board will soon need to be replaced
- The primary control board could display a type of error code if the defrost control board fails
- The system will not run due in part to frost blocking the airflow outside
- Defrosting refuses to run even though there is quite a bit frost that makes the unit run like crap
