International Comfort Products PGAD24D1K1 Defrost Sensor Board
The defrost control board determines when or if to start an important defrosting cycle which actually helps to remove frost build-up that may accumulate. The board is influenced by a sensor located near the condenser to decide when to begin.
What to see if the outdoor defrost sensor board is crapping out?
- The main control board may issue an error of some type referring to a failing defrost control board
- Defrost mode will not kick in especially when there is frost that makes the unit run like crap
- Your HVAC system will stop functioning at all because of the frost issue
