International Comfort Products PGMD36H090C Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence which actually helps to remove frost build-up that may accumulate. The control board looks to a temperature sensor located somewhere by the condenser to decide when to begin.
What warnings should I watch out for to know if my International Comfort Products defrost sensor board is not working right?
- The HVAC system could stop working due to the frost blocking the flow of air
- The main circuit board may show an error number referring to a failing defrost control board
- Unit defrost session refuses to run despite the fact that there is quite a bit frost that makes the unit run like crap
