International Comfort Products C8MPV125J20B1 Defrost Sensor Board
The defrost control board commences the defrosting phase if necessary, to keep your outdoor unit from plugging up. The defrost board depends on a sensor located in the outdoor unit to decide when the defrost cycle should begin.
What happens when my AC defrost sensor board is not working properly?
- The AC may not run due to the frost blocking the flow of air
- The defrost sequence has not run for quite some time even though there is quite a bit frost on the unit
- Your main control board might issue an alphanumeric error code if the defrost board fails
