If you own a combustion furnace that uses natural gas, oil, or propane for heating, then your furnace will contain multiple critical safety switches to detect and prevent unsafe operation. The limit switch is an essential part of this safety system. Limit switches detect out-of-range temperature conditions at both ends of the scale.

The lower end of the range prevents the furnace blower from running when the heat exchanger isn't yet up to temperature.
