The L185F Flame Rollout Switch is a critical safety component designed for residential and commercial gas furnaces. This high limit control switch monitors the temperature near the burner assembly, acting as a safeguard against 'flame rollout' conditions where flames are diverted outside the combustion chamber. If the heat exceeds the calibrated 185°F threshold, the switch opens and immediately interrupts the heating cycle to prevent equipment damage and fire hazards. Featuring a manual reset design, this fan disc-style switch ensures that the HVAC system is inspected before operation resumes, providing an essential layer of protection for your heating equipment. It is a reliable replacement part for maintaining the safe and efficient performance of modern forced-air heating systems.
