International Comfort Products GPCM48L080F Defrost Sensor Board
The defrost sensor control board will begin an important defrosting cycle which helps to keep your outdoor unit from plugging up. The control board looks to a temperature sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Clues of a declining defrost sensor board
- The whole system may not run for the simple fact of the safety issue that the frost poses
- The main control board may throw an alphanumeric error code when encountering a problem
- Self defrost sequence never starts even though there is quite a bit frost that needs to be removed
