International Comfort Products PHAD30N1K1 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost sequence which actually helps to remove frost build-up that may accumulate. It depends on a specific sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
Some clues your International Comfort Products defrost sensor board is going to die
- Self defrost sequence does not begin despite the fact that there is a lot of frost on the external unit
- AC and heating system could stop working at all because of the fact that there is too much frost
- The control board could throw a specific error code referring to a failing defrost control board
