Carrier 58MXB080F10116 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost cycle in order to remove frost build-up that may accumulate. The board looks to a specific sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Signals of a poorly performing outdoor defrost sensor board
- Unit defrost session will not kick in despite that there is a large amount frost that makes the unit run like crap
- The AC may not run for the fact of lack of airflow through the outdoor unit
- Your main control board could display a particular error code produced by a failing defrost board
