Product Details

Description

This 3-inch high limit control switch is a vital safety component designed for furnace and HVAC heating systems. As a thermal protection device, the L120-30F monitors internal temperatures to prevent overheating and potential equipment damage. When the system's air temperature reaches the 120°F safety threshold, the switch automatically opens the circuit to shut down the heating element or burner. Once the unit cools down by 30°F, the switch resets to allow for normal operation. This reliable replacement switch ensures your heating system operates within safe temperature parameters, providing essential protection for residential and commercial HVAC units.
