International Comfort Products GDJ125M20C1 Defrost Sensor Board
The defrost sensor board will begin the defrosting phase if necessary, to remove frost build-up that may accumulate. The control board looks to a sensor located in the outdoor unit to decide when to begin.
What are the signs that the AC defrost sensor board is not working right?
- AC and heating system could cease to function because of the safety issue that the frost poses
- Self defrost sequence has not run for quite some time even though there is a large amount of frost built up
- Your main control board may signify a type of error code if the defrost control board fails
