The 5/8" Flame Rollout Switch is a critical safety component designed for gas-fired furnaces and HVAC heating systems. This manual reset thermal limit switch monitors the temperature near the burner assembly to detect flame rollout—a dangerous condition where flames escape the combustion chamber. When temperatures reach the 200°F (L200F) threshold, the switch opens, instantly interrupting power to the gas valve to prevent equipment damage and ensure household safety. Featuring a compact 5/8-inch disc design, this switch requires a manual reset once it has been tripped, allowing for a professional inspection of the heating system before resuming operation. It is a vital replacement part for maintaining the reliable and safe performance of residential and commercial heating units.
