Carrier 38TDB024 Defrost Sensor Board
The defrost sensor control board commences the defrosting phase if necessary, to keep the outdoor unit free from frost build-up. The defrost board is influenced by a defrost sensor which is near the condenser somewhere, in order to determine when to initiate the defrosting cycle.
Major symptoms the AC defrost sensor board will eventually need to be replaced
- The HVAC system control board may show an error signal produced by a bad defrost control board
- The system may not work for the simple fact of frost blocking the fins on the outside unit
- Defrost mode never runs especially when there is frost that needs to be removed
