This high-limit safety device monitors heat exchanger and burner-area temperatures, opening the control circuit to shut down the furnace if it detects an overheat or flame rollout condition. Because it is a manual reset design, it must be physically reset after tripping — an intentional safety feature that forces a service inspection before the unit can run again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFD18070S3AXCB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Opens on overheat \/ flame rollout, requires manual reset\u003c\/li\u003e\n\u003cli\u003eMounting: Direct OEM bracket fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a genuine Goodman OEM switch calibrated to the exact trip temperature specified for your furnace. Generic aftermarket limit switches may carry a lower price but often use approximate trip points and looser tolerances, which can cause nuisance tripping or, worse, fail to protect the heat exchanger. For a safety-critical component, we recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Replacement is a two-wire, single-bracket job that most handy homeowners can complete in about 15 minutes with basic hand tools. Always disconnect power and gas before servicing. If the switch has tripped, have the underlying cause (blocked flue, failed blower, dirty filter) diagnosed by a licensed HVAC technician before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058215633267,"sku":"GOODMAN-13835","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-wfd18070s3axcb-10123529","provider":"National HVAC Parts","version":"1.0","type":"link"}
