Carrier 38YKC042 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrosting phase which aids to remove frost build-up that may accumulate. The control board relies on a temperature sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Some warnings the defrost sensor board will need replacing
- The AC may not operate due to frost blocking the fins on the outside unit
- The main board may throw an alphanumeric error code when a defrost board fails to initialize
- Defrost session never initiates despite the fact that there is quite a bit frost in the way
