International Comfort Products H9MPD125L20C1 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrosting phase which may be needed in order to remove frost build-up that may accumulate. The defrost board is influenced by a temperature sensor which is near the condenser somewhere, in order to ascertain when to begin.
Hints your outdoor defrost sensor board needs replacing ASAP
- The control board may issue an error code referring to a failing defrost control board
- Defrosting refuses to run even though there is a lot of frost that has built up
- The AC may end up not running due in part to the safety issue that the frost poses
