Mounted on the burner assembly, this manual-reset thermal switch opens the control circuit and shuts off the gas valve if flames roll out of the burner box — a critical condition caused by a blocked flue, cracked heat exchanger, or restricted combustion air. It is a vital safety component that protects your home from fire and carbon monoxide hazards.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370108\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 300°F (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eReset Type: Manual reset button\u003c\/li\u003e\n\u003cli\u003eType: Normally-closed flame rollout safety switch\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GUPI100-4 (100,000 BTU furnace)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370108 is calibrated to the exact 300°F trip point and mounting footprint the GUPI100-4 burner box requires. A generic switch with a different set point can fail to trip during a genuine rollout event or nuisance-trip during normal firing. On a safety-critical component, only genuine Goodman calibration should be trusted.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eRating: Easy (1.5\/5).\u003c\/strong\u003e Usually one or two screws and two spade terminals.
