Mounted on the burner assembly, it trips and shuts off the gas valve if flames roll out of the heat exchanger — a common symptom of a cracked heat exchanger, blocked flue, or restricted combustion air. If your furnace locks out on a rollout fault, this switch must be replaced with the correct OEM part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370108\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 300°F (open on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type:\u003c\/strong\u003e Manual reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally closed safety limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GUI150-5 furnace and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003esafety-critical component\u003c\/strong\u003e — the OEM switch is calibrated to the exact 300°F trip point specified for this furnace.
