The Lennox 31J96 Manual Reset Flame Rollout Switch is a critical safety component designed to protect gas furnaces from dangerous flame rollout conditions.

What It Does:

The flame rollout switch is a crucial safety device that monitors the burner area for abnormal flame patterns. When flames "roll out" beyond the normal combustion chamber due to restricted venting, cracked heat exchangers, or other hazards, this switch opens the electrical circuit and shuts down the furnace burner. The manual reset feature prevents automatic restart, protecting your home from potential carbon monoxide exposure and fire hazards until a qualified technician can diagnose and repair the underlying problem.
