This normally-closed thermal safety switch opens at 120°F to interrupt burner operation whenever it detects abnormal heat or a rollout condition, protecting the heat exchanger and surrounding cabinet from overheating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ rollout limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip point:\u003c\/strong\u003e 120°F (open on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed (SPST)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Bracket \/ clip mount, OEM footprint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80704BXAA and Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e part calibrated to the exact 120°F trip point specified for your furnace. Universal aftermarket switches often ship with generic bimetal discs whose trip tolerance drifts, causing nuisance lockouts or — worse — failing to open when needed. Choosing OEM guarantees the correct temperature rating, terminal style, and mounting geometry so the board's safety logic behaves exactly as designed.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e A basic repair most homeowners can complete in under 15 minutes: shut off power at the disconnect, disconnect the two spade terminals, unscrew the switch bracket, and swap in the new unit. No refrigerant handling or specialty tools required. If your furnace is locking out on a limit fault, always verify airflow (filter, blower, ductwork) before condemning the switch.\u003c\/p\u003e\u003cp\u003eBacked by genuine Goodman quality.
