Lennox CB30M-46 Limit Switch
The limit switch is a switch located in the furnace that determines when the heated air is warm enough that it can be circulated throughout the house. One big reason why limit switches are designed that way is because if the air is not warm enough then you will never get hot air through the ducts.
