The Flame Rollout Switch 3/4" Disc Manual Reset L170F is a vital safety component designed for gas-fired furnaces and residential heating systems. This thermal limit switch acts as a critical failsafe by monitoring the burner assembly area for 'flame rollout'—a hazardous condition where flames escape the combustion chamber due to flue blockages or heat exchanger failure. When temperatures reach the 170°F threshold, the switch opens, immediately interrupting the gas valve circuit to shut down the appliance. Featuring a standard 3/4-inch disc diameter and a manual reset button, this component ensures the heating system remains offline until a technician can inspect and resolve the underlying airflow issue. It is a high-quality replacement part essential for maintaining HVAC safety standards and preventing fire hazards.
