Carrier HH680502 Limit Switch 318172-701 it features adjustable defrost intervalThe Carrier HH680502 Limit Switch is a critical safety component designed for precise thermal monitoring in residential and commercial furnaces. This 90 120F auto reset limit switch functions as a primary high limit control, specifically engineered to open the electrical circuit if internal plenum temperatures exceed the 120F threshold. Once the heat exchanger cools to the 90F reset point, the switch automatically closes, restoring system operation.
