Mounted on the burner box, it senses flames rolling out of the heat exchanger — a symptom of blockage or poor draft — and instantly shuts off the gas valve to prevent fire and heat-exchanger damage. A tripped or open rollout switch is a frequent no-heat cause.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed, opens on over-temp\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMNT100-4B and compatible Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe exact trip point and bracket footprint matter for a safety limit.
