This is a critical safety component: it monitors temperature in the burner or heat exchanger area and opens the circuit to shut down the furnace if it detects an overheat or flame-rollout condition, helping prevent damage to the heat exchanger and reducing fire risk.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Type: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button (does not auto-reset — indicates a fault to investigate)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens on overtemperature to de-energize the gas valve\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFD18045S3AXCB and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a life-safety device, OEM is strongly recommended. The genuine 10123529 is calibrated to the exact factory trip temperature for your furnace. Generic switches with a different setpoint can nuisance-trip or, worse, fail to trip when needed. Do not substitute a switch with an unverified temperature rating.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires shutting off power and gas, removing the burner-compartment panel, disconnecting spade terminals, and transferring the switch. Note wire positions before removal. If a manual reset switch has tripped, always diagnose the root cause (restricted airflow, dirty filter, blocked flue) before resetting. When in doubt, use a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058214289779,"sku":"GOODMAN-13811","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-wfd18045s3axcb-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
