Product Details

Description

This high-quality flame rollout switch fusible link is a critical safety component designed for gas-fired heating systems and furnaces. Functioning as a thermal cutoff, this fuse is engineered to detect abnormal heat levels outside the combustion chamber—a condition known as flame rollout. When the temperature reaches its calibrated threshold of 257°F (125°C), the link melts, immediately breaking the electrical circuit to the gas valve and shutting down the system to prevent fire hazards and equipment damage. If your furnace or boiler is failing to ignite or shutting down unexpectedly, a blown rollout switch is a common cause requiring replacement. This essential HVAC repair part ensures your appliance operates safely and efficiently, protecting your home from dangerous exhaust conditions caused by blocked heat exchangers or venting issues.
