Whirlpool ATE0945RPP0 Defrost Sensor Board
The defrost sensor board determines when or if to start an important defrosting cycle which may be needed in order to rid your unit of frost that can build up. The control board is influenced by a specific sensor located somewhere by the condenser to determine when to initiate the defrosting cycle.
Major clues of a barely functioning AC defrost sensor board
- The main circuit board might issue an alphanumeric error code produced when the defrost control board fails to receive a signal
- AC and heating system could cease to function for the fact of too much frost
- Defrost mode refuses to run despite the fact that there is a lot of frost on the external unit
