This Flame Rollout Limit Switch is a critical safety component designed for gas-fired heating systems, including residential furnaces and commercial rooftop units. Engineered to monitor the temperature around the burner assembly, this 240°F thermal limit control acts as a fail-safe to protect your HVAC equipment and property. If the sensor detects excessive heat—often caused by a blocked flue, cracked heat exchanger, or improper venting—it automatically interrupts the electrical circuit to shut down the gas valve and prevent a fire hazard. Featuring a brown color-coded housing for easy identification during maintenance, this replacement switch ensures your heating system operates within safe thermal parameters. It is an essential part for repairing malfunctioning heating units and restoring safe operation to your furnace.
