Lennox G40UH-48B-090X Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrosting phase which assists to remove frost build-up that may accumulate. The control board depends on a temperature sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
Cues of an inadequate defrost board
- Defrosting does not run especially when there is frost built up
- The primary control board might give out a type of error code produced when the defrost control board fails to receive a signal
- The system will stop functioning due to the fact of frost blocking the airflow outside
