Lennox G40DF-48B-070 Defrost Sensor Board
The defrost sensor board controls if and when to commence an important defrosting cycle in order to get rid of the frost that collects on the outdoor unit. It relies on a defrost sensor located somewhere by the condenser to agree when the defrost cycle should begin.
Subtle hints the AC defrost sensor board will soon need to be replaced
- The control board could throw an error number when encountering a problem
- The defrost sequence will not kick in despite the fact that there is a lot of frost that needs to be removed
- Most systems will cease to operate due to the frost blocking the flow of air
