Carrier 50EZ Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle if necessary, to get rid of the frost that collects on the outdoor unit. The board is relayed information from a sensor located somewhere by the condenser to make the decision on when to begin.
What warnings should I watch out for to know if my outdoor defrost sensor board is in need of a replacement?
- The AC may not operate at all because of the safety issue that the frost poses
- The primary control board could throw an error of some type referring to the failed defrost sequence
- Defrosting never runs especially when there is frost on the outdoor unit
