International Comfort Products HHP042GKA1 Defrost Sensor Board
The defrost sensor control board determines when to initiate the defrosting phase in order to remove frost build-up that may accumulate. The defrost sensor board relies on a defrost sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Some clues your defrost board is going out
- The main control board could signify a specific error code referring to a bad defrost board
- The defrost sequence refuses to run despite the fact that there is quite a bit frost in the way
- The whole system may not operate due to the frost issue
