This normally-closed thermal safety opens the ignition circuit if it senses abnormal heat from flame rollout or a blocked heat exchanger, shutting the furnace down to prevent damage. Because it is a manual-reset device, it stays open after a trip and must be reset by hand — a repeatedly tripping switch signals a combustion or airflow problem that should be investigated.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: 10123529\u003c\/li\u003e\n\u003cli\u003eType: Manual reset thermal limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed (opens on overheat)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80403AXBB furnace\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eType: OEM exact-fit replacement safety control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\n\u003cp\u003eAs a safety-critical control, the genuine OEM 10123529 is calibrated to Goodman's exact trip temperature, so it protects the furnace without nuisance shutdowns. Generic switches with incorrect trip points can either fail to protect or trip prematurely. For a code-compliant safety component, always use OEM.\u003c\/p\u003e\n\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\n\u003cp\u003eA straightforward swap. Disconnect power, note and remove the two spade wire terminals, unscrew the switch from its mounting bracket, install the new switch in the same orientation, and reconnect the wires. Estimated time: 10-15 minutes. Diagnose the cause of any trip before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057600872819,"sku":"GOODMAN-4973","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-amh80403axbb-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
