International Comfort Products T8MPT100J20A1 Limit Switch
The limit switch contains a sensor located in the furnace that makes the determination when the heated air is actually warm enough to activate the main blower. This is important due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Hints of a poorly working limit switch
