Carrier FV4CNB006 Defrost Sensor Board
The defrost sensor board initiates the defrost sequence which helps to get rid of the frost that collects on the outdoor unit. The board is influenced by a sensor located in the outdoor unit to determine when to initiate the defrosting cycle.
Important hints your outdoor defrost sensor board has to be replaced
- Your HVAC system will stop operating for the simple fact of the frost blocking the flow of air
- The HVAC system control board may issue a specific error code referring to the failed defrost sequence
- Self defrost sequence refuses to run despite the fact that there is a lot of frost on the unit
