Carrier FF1DNA030011AAAA Defrost Sensor Board
The defrost sensor board instructs the system to activate an important defrosting cycle which may be necessary to keep the outdoor unit free from frost build-up. The defrost board looks to a specific sensor which is near the condenser somewhere, in order to make the decision on when to begin.
Main clues the AC defrost sensor board is going to die
- The HVAC system could stop working because of the safety issue that the frost poses
- The defrost sequence will not kick in despite the fact that there is a lot of frost that makes the unit run like crap
- The main control board could display an error number produced when the defrost control board fails to receive a signal
