Whirlpool ATR1555SPP0 Limit Switch
The limit switch is a switch located in the furnace that senses, or governs, when the heated air is warmed to a point for the blower to be activated. The reason limit switches exist is because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
