International Comfort Products GPFM36K080F Defrost Sensor Board
The defrost sensor control board commences the defrost cycle which actually helps to keep the outdoor unit free from frost build-up. The defrost board depends on a temperature sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Some clues poorly running outdoor defrost sensor board
- The main circuit board may issue an error number referring to a bad defrost board
- The defrost feature does not begin especially when there is a rather large amount of frost that has built up
- The AC may not operate because of the safety issue that the frost poses
