Mounted on the burner assembly, this rollout switch opens the ignition circuit if flames roll out of the burner box due to a blocked heat exchanger, poor venting, or restricted airflow — shutting the furnace down to prevent overheating and fire hazard. A tripped or failed switch is a common cause of no-heat calls and must be replaced with the correct temperature-rated OEM part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 300°F (manual reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout safety limit\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80905CNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eSingle-pole, normally-closed contacts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis safety device must match the exact 300°F trip point and bracket geometry.
