Lennox 13ACX-042 Defrost Sensor Board
The defrost sensor board controls if and when to commence an important defrosting cycle which actually helps to remove frost build-up that may accumulate. The defrost sensor board relies on a defrost sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
Warnings of a bad AC defrost sensor board
- The AC may not work for the simple fact of lack of airflow through the outdoor unit
- Defrosting does not run despite the fact that there is a lot of frost that needs to be removed
- Your main control board might give out an error code referring to a bad defrost board
