This normally-closed thermal safety trips and latches open on an overtemperature or flame-rollout event, shutting off the burners and requiring a physical pushbutton reset before the furnace can restart. The manual-reset design is intentional: a latched trip flags a real fault (blocked flue, cracked heat exchanger, or airflow failure) that must be diagnosed, not simply cycled past.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual-reset limit \/ flame-rollout switch\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens and latches on temperature rise\u003c\/li\u003e\n\u003cli\u003eReset: Pushbutton (manual)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMH80403AXBA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. quick-connect spades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eManual-reset limits are calibrated to a specific trip temperature matched to this furnace's heat exchanger and rollout location. The OEM 10123529 guarantees that set point and the correct bracket\/terminal orientation. Generic substitutes with a different trip temperature can either nuisance-trip or fail to protect against rollout — unacceptable for a safety control.

Cut power, photograph and transfer the spade wires, remove the mounting screws, and install the new switch in the same position. Important: if the switch had tripped, find and correct the root cause (airflow, venting, or heat exchanger) before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057600545139,"sku":"GOODMAN-4964","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-amh80403axba-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
