International Comfort Products PGMD24G0408 Defrost Sensor Board
The defrost sensor control board will determine when to initiate the defrost sequence in order to rid your unit of frost that can build up. It relies on a defrost sensor which is near the condenser somewhere, in order to make the decision on when to begin.
Hints of an ailing defrost board
- The control board could throw a particular error code when a defrost board fails to initialize
- Defrost session never initiates despite the fact that there is quite a bit frost on the outdoor unit
- AC and heating system could cease to operate for the fact of frost blocking the fins on the outside unit
