Lennox G40UH-36B-090 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost sequence in order to remove frost build-up that may accumulate. It is relayed information from a sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
What are the indications that my outdoor defrost sensor board is in need of a replacement?
- The main control board might give out a specific error code when a defrost board fails to initialize
- The defrost sequence refuses to run especially when there is a rather large amount of frost that makes the unit run like crap
- The system will cease to function due to the fact that there is too much frost
