International Comfort Products HHP036GKA1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost cycle which aids to keep your outdoor unit from plugging up. The defrost board looks to a temperature sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Subtle hints your outdoor defrost sensor board has to be replaced
- The primary control board could display a particular error code if the defrost board goes out
- Self defrost sequence never starts even though there is a large amount of frost on the unit
- The whole system may stop functioning due to the fact of the frost issue
