Carrier FF1DNA018000AAAA Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase which may be necessary to rid your unit of frost that can build up. The board relies on a defrost sensor located near the condenser to agree when to initiate the defrosting cycle.
Major clues of a failing defrost board
- Your main control board could display an alphanumeric error code if the defrost board fails
- AC and heating system could cease to operate due to the fact of too much frost
- Defrost session has not run for a while even though there is quite a bit frost built up
