International Comfort Products HHP236GKA1 Defrost Sensor Board
The defrost control board controls if and when to commence the defrosting phase which aids to continue normal heating and cooling operations. The control board depends on a specific sensor located in the outdoor unit to make the decision on when to initiate the defrosting cycle.
Subtle hints the defrost sensor board will have to be replaced
- The defrost sequence never runs especially when there is a rather large amount of frost built up
- The main control board may throw a particular error code if the defrost control board fails
- Your system could stop running at all because of the safety issue that the frost poses
