Lennox WING Defrost Sensor Board
The defrost control board initiates the defrosting phase which actually helps to rid your unit of frost that can build up. The board relies on a specific sensor located near the condenser to make the decision on when the defrost cycle should begin.
What are some indications that my AC defrost sensor board really needs to be replaced?
- The defrost sequence refuses to initiate even though there is a large amount of frost that has built up
- The system will not operate because of too much frost
- The main circuit board could throw an error signal produced when the defrost board is bad

Before buying or ordering a replacement defrost sensor board for your Lennox WING do your best and double check the model number and also make a visual inspection so that you are positive that the proper replacement defrost sensor board is being ordered. There is no rule that says you have to replace the part all by yourself. Search for a pro in your town or city to replace the part.
