This is a critical safety control — a tripped or failed rollout switch should always be diagnosed for root cause, not just replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eType: Flame rollout safety limit, manual reset\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed, opens on overtemp\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT070-3B and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370145\u003c\/strong\u003e is calibrated to trip at exactly 300°F with the correct bracket geometry for burner-box mounting.
