International Comfort Products C9MPD080J16B1 Defrost Sensor Board
The defrost sensor board controls if and when to commence an important defrosting cycle if necessary, to keep your outdoor unit from plugging up. It relies on a temperature sensor which is near the condenser somewhere, in order to agree when to begin.
Red flags your defrost board is dead
- Unit defrost session never begins even though there is quite a bit frost that makes the unit run like crap
- The HVAC system control board could signify an error code referring to a bad defrost board
- AC and heating system could end up not running for the simple fact of the fact that there is too much frost
