Mounted on the burner box, this manual-reset safety switch opens the ignition circuit if flame rolls out of the heat exchanger — protecting the cabinet, wiring, and occupants from a dangerous combustion fault. A tripped or failed rollout switch will shut the furnace down and must be replaced with an exact-rated part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Flame rollout limit switch (manual reset)\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eAction: Opens on temperature rise\u003c\/li\u003e\n\u003cli\u003eFits: AMS80904BXA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eTerminals: Standard 1\/4 inch quick-connect\u003c\/li\u003e\n\u003cli\u003eOEM Part: B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a safety-critical component — the genuine Goodman switch is calibrated to trip at the exact 300°F setpoint your furnace's design requires. A mis-rated generic switch may nuisance-trip or, worse, fail to open during a real rollout event. Never substitute a different temperature rating. OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Shut off power, note the wire positions, unscrew the switch from the burner box, and mount the replacement with the same orientation.
