The L120-20F Disc Limit Switch is a professional-grade thermal safety component designed for use in residential and commercial HVAC systems. This high-limit control switch plays a critical role in furnace safety by monitoring the temperature within the heat exchanger. Engineered to prevent overheating, the switch automatically opens the electrical circuit when the internal temperature reaches 120°F, shutting down the heating source. As an automatic reset model, it restores connectivity once the temperature drops by its 20°F differential (resetting at 100°F). This reliable fan disc switch is an essential replacement part for restoring the safety and efficiency of gas or electric furnaces and air handlers.
