Mounted near the burner box, it protects against flame rollout caused by a blocked heat exchanger, cracked flue, or restricted venting. When it trips it cuts the gas valve and shuts the furnace down until the fault is corrected and the button is manually reset.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eReset type: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout \/ high-limit safety cutout\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. quick-connect\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT090-4 furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a \u003cstrong\u003esafety-critical control\u003c\/strong\u003e, we strongly recommend the \u003cstrong\u003eOEM B1370145\u003c\/strong\u003e — its trip point and reset behavior are matched exactly to the GMT090-4 burner design. Generic 300°F switches exist at lower cost, but tolerance drift on a safety device can mean nuisance trips or, worse, a late trip. When in doubt, use OEM.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eTypically a 10–15 minute repair. Shut off power and gas, note the wire positions, remove two mounting screws, transfer the two quick-connect leads, and mount the new switch.
