International Comfort Products PGF042K080F Defrost Sensor Board
The defrost control board controls if and when to commence the defrost cycle if necessary, to continue normal heating and cooling operations. It is relayed information from a specific sensor located in the outdoor unit to decide when to initiate the defrosting cycle.
How can I tell if my AC defrost sensor board is in need of replacing?
- Air conditioning may end up not running because of way too much frost build-up
- The primary control board could signify a particular error code produced by a bad defrost control board
- The defrost sequence never initiates even when there is a large quantity of frost on the unit
