Whirlpool ATE0952SPP0 Limit Switch
The limit switch has a sensor in the heat exchanger that determines when the heated air is actually warm enough to activate the main blower. Limit switches are built because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air.
Important hints critical limit switch needs replacing ASAP
