International Comfort Products PGMD48G1354 Defrost Sensor Board
The defrost control board determines when or if to start the defrosting phase which may be needed in order to remove frost build-up that may accumulate. The board is influenced by a temperature sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
Important clues of an ailing AC defrost sensor board
- Defrost mode never kicks in especially when there is a rather large amount of frost that has built up
- Your main control board might issue an error of some type produced when the defrost board is bad
- Air conditioning may stop working for the fact of the frost issue
