Carrier FF1DNE024000AAAA Defrost Sensor Board
The defrost sensor control board controls when to launch the defrosting phase which may be needed in order to defrost your outdoor unit. The board is relayed information from a temperature sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
How do you know if your AC defrost sensor board is not working properly?
- The main circuit board could display a type of error code if the defrost board goes out
- Your HVAC system will stop running due in part to the frost blocking the flow of air
- The defrost sequence will not kick in even though there is a lot of frost built up
