International Comfort Products C8MPN050B12B1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase which aids to remove frost build-up that may accumulate. The control board looks to a temperature sensor located near the condenser to verify when to initiate the defrosting cycle.
Elements to watch for in a failing outdoor defrost sensor board
- Your HVAC system will stop operating due in part to the safety issue that the frost poses
- Unit defrost session never starts especially when there is frost in the way
- The control board might issue an error code produced by a bad defrost control board
