Lennox G40DF-60D-135 Defrost Sensor Board
The defrost sensor board will begin the defrost cycle which actually helps to rid your unit of frost that can build up. The board is relayed information from a temperature sensor which is near the condenser somewhere, in order to agree when the defrost cycle should begin.
Main clues your Lennox defrost sensor board has very little life left
- The main circuit board could display a specific error code referring to the failed defrost sequence
- Your HVAC system will end up not running because of the frost blocking the flow of air
- Defrost mode does not run even though there is a lot of frost that needs to be removed
