International Comfort Products HHP230AKA1 Defrost Sensor Board
The defrost sensor control board initiates an important defrosting cycle which actually helps to keep your outdoor unit from plugging up. It is relayed information from a defrost sensor located in the outdoor unit to ascertain when the defrost cycle should begin.
How do you know if your International Comfort Products defrost sensor board is about to stop working?
- Self defrost sequence never starts despite the fact that there is quite a bit frost that has built up
- The main circuit board might issue an alphanumeric error code referring to a bad defrost board
- The system will stop functioning because of frost blocking the fins on the outside unit
