Mounted at the burner box, it senses flame that rolls out of the combustion chamber — a sign of a blocked heat exchanger or restricted venting — and instantly cuts power to the gas valve to prevent a fire hazard. A tripped or open rollout switch is a hard no-heat lockout, and this is the exact replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370108\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Flame rollout limit switch, manual reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Point:\u003c\/strong\u003e 300°F open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GUS100-4 gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e De-energizes gas valve on flame rollout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman switch is calibrated to the exact 300°F trip point and uses the correct bracket and terminal spacing for a bolt-in fit. Because this is a life-safety device, matching the OEM temperature rating is essential — a generic switch with the wrong trip point can nuisance-trip or, worse, fail to protect.
