Nordyne MS3BA030KA Defrost Sensor Board
The defrost control board determines when or if to start the defrost cycle in order to defrost your outdoor unit. The board relies on a defrost sensor located in the outdoor unit to make the decision on when to initiate the defrosting cycle.
What happens when my defrost board is not working right?
- The AC may stop working due in part to way too much frost build-up
- The control board might give out a specific error code produced when the defrost board is bad
- Defrost mode refuses to initiate especially when there is frost in the way
