Carrier 58MVP100 Defrost Sensor Board
The defrost control board will begin the defrost sequence which helps to remove frost build-up that may accumulate. The board is influenced by a specific sensor located somewhere by the condenser to determine when to initiate the defrosting cycle.
How do you know if your AC defrost sensor board is in need of replacing?
- Defrosting never initiates even though there is quite a bit frost that needs to be removed
- The primary control board may issue an alphanumeric error code if the defrost board goes out
- Your system could stop running due to the fact of the amount of frost on the outdoor unit
