Carrier 38HD Defrost Sensor Board
The defrost control board initiates the defrost cycle in order to defrost your outdoor unit. The control board looks to a temperature sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
Simple indications of an inadequate outdoor defrost sensor board
- Defrosting never begins despite the fact that there is quite a bit frost that makes the unit run like crap
- Most systems will end up not running for the simple fact of too much frost
- Your main control board could throw an error signal referring to a bad defrost board
