Carrier 38HDC036 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrost sequence if necessary, to remove frost build-up that may accumulate. The defrost sensor board relies on a sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Key clues of a worsening defrost sensor board
- Unit defrost session never starts even though there is quite a bit frost on the outdoor unit
- The system may not run because of the frost issue
- Your main control board might issue an error signal produced by a failing defrost board
