Lennox CBX32M-024 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost sequence which helps to remove frost build-up that may accumulate. The control board is influenced by a defrost sensor which is near the condenser somewhere, in order to determine when to begin.
Major symptoms your Lennox defrost sensor board should be replaced
- The main control board might give out an error signal produced by too much frost
- The defrost feature never begins even though there is excessive frost that needs to be removed
- The AC may cease to operate for the fact of frost blocking the airflow outside
