International Comfort Products C9MPD050F12C2 Defrost Sensor Board
The defrost sensor board initiates the defrost cycle in order to keep your outdoor unit from plugging up. The control board relies on a temperature sensor located somewhere by the condenser to agree when to begin.
Clues to watch for to know the defrost sensor board is going out
- The HVAC system control board may throw an alphanumeric error code when encountering a problem
- Your system could cease to function due in part to the fact that there is too much frost
- Unit defrost session does not begin despite the fact that there is a lot of frost that needs to be removed
