Whirlpool ATR0942BPP0 Defrost Sensor Board
The defrost control board determines when or if to start the defrost cycle in order to remove frost build-up that may accumulate. It depends on a sensor that can be found near the condenser, in order to make the decision on when to initiate the defrosting cycle.
Red flags the defrost sensor board should be replaced
- The control board might give out a type of error code referring to a failing defrost control board
- Unit defrost session refuses to run despite the fact that there is a lot of frost that has built up
- The HVAC system could end up not running for the simple fact of too much frost
