Whirlpool ATR0743RPP0 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrosting phase which helps to keep your outdoor unit from plugging up. The defrost sensor board depends on a temperature sensor which is near the condenser somewhere, in order to verify when the defrost cycle should begin.
Warnings your defrost board is not going to last much longer
- The AC may end up not running for the fact of frost blocking the fins on the outside unit
- The main board might issue a type of error code referring to the failed defrost sequence
- Self defrost sequence never kicks in even though there is quite a bit frost on the unit
