International Comfort Products GPCM48H120F Defrost Sensor Board
The defrost sensor control board will begin the defrost sequence which may be needed in order to rid your unit of frost that can build up. The defrost sensor board is relayed information from a temperature sensor located in the outdoor unit to decide when to begin.
What are the signs that the defrost sensor board is crapping out?
- The AC may stop operating for the simple fact of the amount of frost on the outdoor unit
- The defrost feature will not kick in especially when there is a rather large amount of frost that has built up
- The primary control board could signify an error of some type if the defrost board fails
