This normally-closed rollout\/limit switch monitors heat exchanger and burner-box temperatures and opens the ignition circuit if an unsafe over-temperature or flame-rollout condition occurs, shutting down the furnace to prevent damage and protect your home.\u003c\/p\u003e\u003cp\u003eBecause it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it will not auto-cycle after a fault — the switch must be physically reset once the underlying cause (blocked flue, failed blower, cracked heat exchanger, or dirty burners) has been corrected. This is a deliberate safety design that forces inspection before the furnace can run again.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine OEM Goodman \/ Amana replacement part number \u003cstrong\u003e10123529\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eManual reset rollout \/ limit switch — normally closed\u003c\/li\u003e\n\u003cli\u003eDirect fit for AMH80903BXCA and related 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated trip temperature — no field adjustment required\u003c\/li\u003e\n\u003cli\u003e1\/4\" quick-connect terminals for plug-and-play wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine OEM switch ships with the exact factory trip point and bracket geometry, so it drops into the original mounting location and matches the furnace's published safety specs. Universal aftermarket switches often require rework of brackets or terminals and may carry a different calibration, which can cause nuisance lockouts or, worse, fail to trip at the correct temperature. For a life-safety component we always recommend OEM.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty: Easy (1\/5).\u003c\/strong\u003e Turn off power and gas, disconnect the two spade terminals, remove the mounting screw(s), install the new switch in the same orientation, and reconnect. Typically a 10–15 minute repair with a nut driver. If the switch keeps tripping after replacement, diagnose airflow and combustion before running the furnace.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057629872499,"sku":"GOODMAN-5735","price":9.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-amh80903bxca-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
