Carrier 48JZ030060300 Defrost Sensor Board
The defrost sensor board initiates the defrost sequence in order to remove frost build-up that may accumulate. The board relies on a specific sensor located somewhere by the condenser to determine when the defrost cycle should begin.
What are the clues to watch out for to know my Carrier defrost sensor board is about to go out?
- The primary control board could signify an error of some type referring to a failing defrost control board
- The system will stop running because of the safety issue that the frost poses
- Defrosting never kicks in despite the fact that there is quite a bit frost on the outdoor unit
