The Limit Switch Manual Reset L200F is a vital safety component designed for gas furnace heating systems. Functioning as a flame rollout switch, this part monitors the area around the burners for excessive heat or escaping flames. If a flame rollout occurs—where flames are diverted outside the heat exchanger—the switch triggers an immediate system shutdown to prevent damage and ensure household safety. Because it features a manual reset design, the furnace will remain off until the switch is manually reactivated, encouraging a necessary inspection of the combustion system. This L200F limit switch is engineered to open at 200°F, providing precise thermal protection and reliability for residential HVAC units.
