This Flame Rollout Limit Switch is a vital safety component designed for residential gas furnaces and heating systems. Its primary function is to monitor the burner compartment for 'flame rollout'—a hazardous condition where flames escape the heat exchanger. When excessive heat is detected, the switch automatically opens the electrical circuit to shut down the gas valve, preventing potential fire damage and equipment overheating. Featuring an auto-reset design, this L140-40F limit control is calibrated to trip at 140°F and restore operation once the temperature drops by 40°F. Reliable and easy to install, this switch is an essential replacement part for maintaining the safety and efficiency of your forced-air heating equipment.
