This high-quality L180-40F high limit control switch is an essential safety component for residential and commercial HVAC systems. Designed as a fan disc thermostat, this thermal cutout monitors the internal temperature of furnaces and heating units to prevent overheating. When the air temperature reaches the 180°F safety threshold, the switch opens the electrical circuit to shut down the heat source, protecting your equipment from damage and ensuring safe operation. The switch features a 40°F differential, meaning it will automatically reset and close the circuit once the unit cools down to 140°F. This reliable replacement limit switch is perfect for furnace repair, blower motor protection, and maintaining the efficiency of forced-air heating systems.
