Positioned near the burner assembly, it detects flame or heat rolling out of the burner box — a symptom of a blocked heat exchanger, clogged flue, or restricted combustion air — and immediately shuts off the gas valve to prevent fire and CO hazards. This is a critical, life-safety component.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 300°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset type:\u003c\/strong\u003e Manual reset (button)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally-closed safety limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GUPI075-4 burner assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370108\u003c\/strong\u003e is calibrated to the exact 300°F factory trip point and bracket for a guaranteed-correct safety response.
