The Flame Rollout Switch Manual Reset L300F is a vital safety component designed for gas-fired furnace and heating systems. This high-temperature limit sensor monitors the burner compartment for 'flame rollout'—a dangerous condition where flames escape the combustion chamber due to heat exchanger cracks or venting blockages. If temperatures exceed the 300-degree Fahrenheit threshold, the switch automatically breaks the electrical circuit to shut down the heating system, preventing fire hazards. Featuring a manual reset button, this HVAC safety switch ensures that the system cannot be restarted until the cause of the rollout is inspected and resolved by a professional. It is an essential replacement part for maintaining the safety and reliability of residential and commercial forced-air furnaces.
