Carrier 58MXB080F10120 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrosting phase which actually helps to rid your unit of frost that can build up. It depends on a specific sensor located near the condenser to make the decision on when to initiate the defrosting cycle.
Signs of a weak AC defrost sensor board
- Your system could stop operating because of the frost blocking the flow of air
- Defrosting never runs even though there is excessive frost built up
- The main circuit board may issue an error number produced by too much frost
