The FLAME ROLLOUT SWITCH MANUAL RESET L285F is a vital safety component designed for residential gas furnaces and heating systems. This furnace rollout sensor is engineered to monitor the temperature near the burner assembly, providing a critical line of defense against flame rollout. If the sensor detects excessive heat escaping from the combustion chamber—typically caused by a blocked flue or a compromised heat exchanger—it automatically interrupts the electrical circuit to shut down the gas valve and prevent a fire hazard. Featuring a manual reset button, this limit switch ensures that the heating system cannot be restarted until a technician or homeowner has inspected the unit for safety. This L285F switch is calibrated to open at a fixed temperature of 285°F, making it an essential replacement part for maintaining the safe, reliable operation of your HVAC equipment.
