International Comfort Products C8MPN075B12B1 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost sequence which may be needed in order to keep your outdoor unit from plugging up. The control board is relayed information from a defrost sensor that can be found near the condenser, in order to ascertain when the defrost cycle should begin.
Hints to watch for in a bad defrost sensor board
- The system will not run due in part to the frost blocking the flow of air
- Defrost session has not run for quite some time even though there is quite a bit frost that has built up
- The primary control board could display an error code produced when the defrost board is bad
