International Comfort Products PGF042K100F Defrost Sensor Board
The defrost sensor board commences the defrost sequence which may be necessary to continue normal heating and cooling operations. It depends on a temperature sensor located near the condenser to ascertain when to begin.
What are the signs that the AC defrost sensor board has a need to be replaced?
- Air conditioning may not run for the simple fact of the amount of frost on the outdoor unit
- The control board may issue a particular error code produced by a failing defrost board
- Defrosting never kicks in despite the fact that there is a lot of frost on the unit
