The Flame Rollout Switch L400F is a critical safety component engineered for gas-fired furnaces and heating systems. This high-temperature limit switch is designed to detect 'flame rollout,' a hazardous condition where flames escape the combustion chamber due to flue blockages or heat exchanger issues. Once the temperature reaches the 400°F safety threshold, the switch trips and interrupts the electrical circuit, immediately shutting down the burner to prevent fire damage and ensure the safety of your home. Featuring a manual reset design, this thermal sensor is an essential replacement part for maintaining the integrity of your HVAC system's safety circuit.
