This manual-reset switch opens the ignition circuit if flame rolls out of the burner box, shutting down the furnace to prevent overheating, heat exchanger damage, and unsafe combustion conditions. It is a critical, code-required safety device and one of the most common causes of a furnace that locks out on ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1370154\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\u003eTrip Temperature:\u003c\/strong\u003e 350°F (open on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Normally closed, opens on overtemp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMPN040-3 gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana (Daikin)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory-authorized Goodman OEM component, calibrated to the exact 350°F trip point specified for your furnace's burner assembly.
