Whirlpool ATR0942RPP0 Defrost Sensor Board
The defrost sensor control board commences the defrost cycle if necessary, to remove frost build-up that may accumulate. The defrost sensor board is influenced by a temperature sensor which is near the condenser somewhere, in order to determine when to initiate the defrosting cycle.
Clues the defrost sensor board is in need of replacing
- Most systems will not operate due in part to the safety features installed
- The defrost sequence has not run for a while especially when there is frost in the way
- The HVAC system control board could display a specific error code produced by a bad defrost control board
