Carrier FF1DNA018075AAAA Defrost Sensor Board
The defrost sensor board will begin an important defrosting cycle which may be necessary to continue normal heating and cooling operations. The defrost sensor board looks to a sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
Key clues to watch for in a bad outdoor defrost sensor board
- The system will cease to function at all because of the fact that there is too much frost
- Your main control board may throw an error number produced by too much frost
- Unit defrost session never kicks in despite the fact that there is quite a bit frost that makes the unit run like crap
