Carrier KFCEH0601C05 Defrost Sensor Board
The defrost sensor control board determines when to initiate the defrosting phase which may be needed in order to keep your outdoor unit from plugging up. The board is influenced by a temperature sensor located near the condenser to determine when to begin.
Indications of a defective AC defrost sensor board
- Self defrost sequence does not run even though there is a lot of frost that needs to be removed
- The HVAC system control board might give out an error signal if the defrost board goes out
- Your HVAC system will not run due in part to way too much frost build-up
