This temperature-activated safety control monitors for overheating or flame rollout and cuts power to the burners if a dangerous high-temperature condition is detected. Because it is a manual-reset device, it stays open after tripping until an operator presses the reset button — signaling that the underlying fault (blocked airflow, dirty filter, failing blower) should be investigated.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123539\u003c\/li\u003e\n\u003cli\u003eType: manual reset limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eAction: normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003eReset: manual (push-button)\u003c\/li\u003e\n\u003cli\u003eFunction: overheat and flame-rollout protection\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMEC960804CNAB and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eSafety controls are not the place to improvise. The OEM 10123539 is calibrated to the furnace's factory trip temperature and mounting footprint, ensuring it opens at the correct threshold. Generic switches with different trip points can nuisance-trip or, worse, fail to protect against a genuine overheat. Always use the OEM-specified part for safety circuits.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires shutting off gas and power, disconnecting the wire leads, and unbolting the switch from the burner box or heat exchanger. Basic hand tools and a multimeter recommended. If a tripped switch keeps reopening, diagnose the root cause before returning the furnace to service — professional service advised.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057575969139,"sku":"GOODMAN-4239","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-amec960804cnab-10123539","provider":"National HVAC Parts","version":"1.0","type":"link"}
