It opens the control circuit if it senses excessive temperature — protecting the heat exchanger and cabinet from overheating or flame rollout. Because it is a manual-reset device, a tripped switch signals an underlying problem (restricted airflow, blocked flue, or overfiring) and must be physically reset after the fault is corrected.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123529\u003c\/li\u003e\n\u003cli\u003eType: manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: opens on overtemperature to shut down the burner circuit\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80403ANBB furnaces\u003c\/li\u003e\n\u003cli\u003eIncludes reset button for post-fault restart\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a safety-critical control, so the OEM trip and reset temperatures matter. The genuine 10123529 is calibrated to the exact set point Goodman specified for this furnace. Generic \"universal\" limits may trip early (nuisance shutdowns) or late (dangerous overtemperature), and can void heat-exchanger warranty coverage. Always match OEM for safety switches.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — 15–20 minutes. Cut power, disconnect the two spade terminals, remove the mounting screws, install the new switch, and reconnect. Never bypass a limit switch. If it keeps tripping, diagnose the airflow or venting cause.\u003c\/p\u003e\u003cp\u003eConfirm your furnace is the AMH80403ANBB before ordering; several Goodman limit switches look similar but carry different set points.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057599660403,"sku":"GOODMAN-4926","price":7.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-amh80403anbb-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
