Whirlpool ATR0945BPP0 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence which may be necessary to rid your unit of frost that can build up. The board looks to a temperature sensor that can be found near the condenser, in order to determine when to initiate the defrosting cycle.
Signs your Whirlpool defrost sensor board is in dire straights
- Your main control board might give out an error number produced when the defrost control board fails to receive a signal
- Unit defrost session does not run even though there is quite a bit frost on the unit
- The whole system may cease to function due to the fact of the frost blocking the flow of air
