International Comfort Products HHP060AKA1 Defrost Sensor Board
The defrost control board determines when or if to start the defrost sequence which actually helps to get rid of the frost that collects on the outdoor unit. The defrost sensor board relies on a defrost sensor which is near the condenser somewhere, in order to determine when to initiate the defrosting cycle.
Symptoms the defrost sensor board will have to be replaced
- Air conditioning may stop operating for the simple fact of the safety issue that the frost poses
- The main circuit board may throw a specific error code referring to a bad defrost board
- The defrost feature never initiates even though there is a lot of frost that makes the unit run like crap
