This normally-closed switch opens and locks out the gas valve if it senses flame rollout or excessive heat at the burner box — a critical safety response to a blocked flue, cracked heat exchanger, or failed inducer. Unlike an auto-reset limit, it must be manually reset with the button after the fault is corrected, ensuring a technician verifies the cause before the furnace fires again.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine OEM Goodman\/Amana part number 10123529\u003c\/li\u003e\n\u003cli\u003eDirect fit for AMES800403AXAA and compatible AMES80 \/ GMES80 series furnaces\u003c\/li\u003e\n\u003cli\u003eManual-reset, normally-closed thermal safety switch with factory trip temperature\u003c\/li\u003e\n\u003cli\u003eProtects against flame rollout and burner-box overheating\u003c\/li\u003e\n\u003cli\u003ePush-button reset requires the fault be cleared before relight\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM version\u003c\/strong\u003e guarantees the exact factory trip temperature and mounting footprint that the furnace's safety certification depends on.

Shut off gas and power, remove the two mounting screws, transfer the spade wires one at a time to avoid mixups, and reinstall. Important: a switch that trips again immediately signals an active safety condition (blocked venting, dirty burners, cracked heat exchanger) that must be diagnosed — never jumper a safety switch.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057589961075,"sku":"GOODMAN-10123529","price":7.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-ames800403axaa-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
