International Comfort Products PGC048H120F Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrosting phase in order to remove frost build-up that may accumulate. The board looks to a defrost sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
Subtle hints your International Comfort Products defrost sensor board is failing
- Self defrost sequence will not initiate despite the fact that there is a lot of frost in the way
- The primary control board may throw an error number produced by a bad defrost control board
- The AC may cease to function due in part to too much frost
