NORDYNE 626461R Limit Switch, Switching Action: Manual Reset, Fixed Programming, For Use With: Forced-Air Furnaces

A furnace limit switch is a component of a forced air furnace that is responsible for turning on the furnace blower once the desired heat has been reached. Limit switches regulate when your home is heated by gauging the temperature of the surrounding air. If the temperature inside the furnace gets too hot, the limit will open up, resulting in the burners shutting off. This limit opens at 160 deg. It includes a manual reset along with fixed programming.
