International Comfort Products PGME42G1155 Defrost Sensor Board
The defrost control board instructs the system to activate an important defrosting cycle which helps to remove frost build-up that may accumulate. It looks to a sensor located near the condenser to determine when to initiate the defrosting cycle.
Major clues your defrost board is in dire straights
- The defrost feature does not begin especially when there is frost on the outdoor unit
- The HVAC system could not work for the fact of too much frost
- The main circuit board could signify a specific error code if the defrost board goes out
