Mounted on the burner assembly, this manual-reset safety device instantly cuts power to the gas valve if flames roll out of the burner box — a dangerous condition typically caused by a blocked heat exchanger, cracked flue, or restricted venting. It is a critical life-safety component that should never be bypassed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 300°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual-reset flame rollout switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement for DDS81155CXA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana genuine OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman B1370145 switches are calibrated to trip at the precise 300°F threshold your furnace's safety circuit is designed around, with a mounting footprint that matches the burner assembly exactly. Generic rollout switches may trip early (nuisance shutdowns) or late (unsafe), and often require bracket modification. On a safety cutoff, matching the OEM specification is essential.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy (2\/5)\u003c\/h3\u003e\u003cp\u003eShut off power and gas, remove the two mounting screws, transfer the spade wire connectors to the new switch, and reinstall.
