Lennox Flame Rollout Switch - Manual Reset

The Lennox Flame Rollout Switch (also called a burner rollout switch or flame rollout limit switch) is a manual-reset safety control for gas furnaces and HVAC heating equipment. It sits near the burner assembly. If flames move out of the combustion zone, it detects the heat and shuts the system down.

Key Features:

• Manual reset design: After the switch trips, someone must press the reset button before the burners can fire again. This stops the unit from restarting on its own until the cause has been checked.
• Overheat and flame rollout protection: When the switch reaches its rated trip temperature, it opens the safety circuit. That closes the gas valve and stops fuel delivery to the burners.
• Genuine Lennox OEM replacement: Built to Lennox factory specifications, so it works correctly with the original safety circuit.
• Thermal sensing: A heat-sensitive element monitors the area around the burners.
• Multiple trip temperature ratings: The product line includes several switch models. Check the individual part listing for the rating you need.

A rollout switch can trip when the venting is blocked, the inducer isn't drawing enough air, or combustion is abnormal. If a switch trips repeatedly, have a qualified technician inspect the furnace. Choose the variant that matches your original part number to restore the factory safety function.
