Ensure the safety and efficiency of your gas furnace with this high-quality Flame Rollout Switch. Designed as a critical safety component for HVAC systems, this L190F manual reset limit switch monitors the temperature near the burner assembly. If the device detects excessive heat or flames 'rolling out' of the heat exchanger—often caused by venting issues or blockages—it instantly interrupts the electrical circuit to shut down the gas valve. This thermal limit switch features a fixed 190°F trip point and a manual reset button, requiring a physical inspection of the heating system before operation can resume, which adds an essential layer of protection for your home. This replacement part is vital for maintaining a functional and code-compliant residential or commercial heating system.
