Carrier 48DD Defrost Sensor Board
The defrost sensor board commences the defrost sequence which actually helps to remove frost build-up that may accumulate. The defrost sensor board looks to a temperature sensor located in the outdoor unit to agree when to initiate the defrosting cycle.
Some warnings your outdoor defrost sensor board needs replacing ASAP
- The main circuit board may show a specific error code when the defrost board fails
- The defrost sequence never runs even though there is quite a bit frost in the way
- The system may stop operating due in part to the frost blocking the flow of air
