Mounted near the burner box, it senses flame rollout — flames escaping the heat exchanger due to a blocked flue, cracked exchanger, or bad draft — and cuts power to the gas valve before the condition becomes dangerous. If your furnace locks out and won't restart, a tripped rollout switch is a common cause, but always find and fix the root problem before resetting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 300°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally closed safety limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e B1370108\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e GUPI120-5 furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a \u003cstrong\u003esafety-rated\u003c\/strong\u003e component, we strongly recommend the \u003cstrong\u003eOEM B1370108\u003c\/strong\u003e — its trip point and reset behavior are validated to Goodman spec.
