International Comfort Products GPFM48H120F Defrost Sensor Board
The defrost sensor control board initiates the defrost cycle which may be necessary to keep your outdoor unit from plugging up. It relies on a temperature sensor located somewhere by the condenser to agree when to initiate the defrosting cycle.
Major indications your defrost board will need to be replaced
- The AC may cease to function for the fact of the safety features installed
- Defrost mode never initiates even though there is a lot of frost that has built up
- The main board may issue a specific error code if the defrost board goes out
