Whirlpool ATE1243BPP0 Defrost Sensor Board
The defrost sensor board will begin an important defrosting cycle which may be needed in order to remove frost build-up that may accumulate. It looks to a specific sensor located somewhere by the condenser to agree when to initiate the defrosting cycle.
Key signs of a poorly performing outdoor defrost sensor board
- The main control board could throw an error of some type produced by a failing defrost board
- Your system could not operate at all because of the safety issue that the frost poses
- The defrost sequence never begins even though there is excessive frost on the outdoor unit
