International Comfort Products T9MPD125L20A1 Defrost Sensor Board
The defrost control board controls when to launch an important defrosting cycle which helps to rid your unit of frost that can build up. The board depends on a temperature sensor located somewhere by the condenser to verify when to begin.
Important hints your defrost board has to be replaced
- Defrosting never runs despite the fact that there is quite a bit frost that makes the unit run like crap
- The primary control board may show an error of some type when encountering a problem
- The system will not operate because of the safety issue that the frost poses
