Ensure the safety and reliability of your residential heating system with this high-quality flame rollout switch, designed for compatibility with Armstrong Air and Lennox gas furnaces. This essential safety component is engineered to detect 'flame rollout'—a condition where flames escape the combustion chamber—by monitoring the temperature near the burner assembly. Once the switch reaches its calibrated thermal limit, it interrupts the electrical circuit to shut down the gas valve, preventing potential equipment damage or hazardous conditions. Featuring a manual reset design, this limit switch is a critical replacement part for HVAC maintenance and repair, ensuring your furnace operates within strict safety parameters. If your heating system is frequently tripping or failing to sustain a flame, replacing a worn or faulty rollout switch can restore proper functionality and peace of mind.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
