International Comfort Products GPCM36H080F Defrost Sensor Board
The defrost control board will determine when to initiate the defrost cycle if necessary, to keep your outdoor unit from plugging up. The board is influenced by a temperature sensor that can be found near the condenser, in order to ascertain when to initiate the defrosting cycle.
Some clues your defrost board needs a replacement ASAP
- Unit defrost session never kicks in especially when there is a rather large amount of frost that makes the unit run like crap
- The main circuit board might give out a type of error code if the defrost board fails
- The system may not run for the simple fact of the amount of frost on the outdoor unit
