International Comfort Products T9MPV050F12A1 Defrost Sensor Board
The defrost sensor control board commences the defrosting phase which helps to keep the outdoor unit free from frost build-up. The board is influenced by a defrost sensor which is near the condenser somewhere, in order to make the decision on when to initiate the defrosting cycle.
Easy warnings of an ailing outdoor defrost sensor board
- Unit defrost session never starts despite the fact that there is a lot of frost that needs to be removed
- The system will stop running at all because of too much frost
- The primary control board could throw an error of some type produced when the defrost control board fails to receive a signal
