This switch monitors heat-exchanger and burner-area temperature, opening the 24V control circuit to shut down the burners if an unsafe over-temperature or flame-rollout condition is detected. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it locks out until the cause is corrected and the button is physically pressed — an intentional safety design that flags a recurring problem rather than silently cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eMounting: OEM bracket-mount, direct replacement\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADSH800403AXAB and compatible 80% gas 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\u003eThe genuine Goodman 10123529 is calibrated to the exact trip temperature specified for your furnace's heat exchanger. Generic substitutes may carry a similar form factor but often differ in set-point or reset behavior, risking nuisance lockouts or — worse — delayed shutdown. For a UL-listed safety component, OEM is the recommended choice.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy (2\/5)\u003c\/h3\u003e\u003cp\u003eReplacement is a basic two-wire swap. Shut off power and gas, remove the burner-compartment panel, disconnect the spade terminals, unscrew the old switch, and mount the new one in the same orientation. Most homeowners with basic tools complete this in 15–20 minutes. If the switch trips repeatedly after replacement, have the furnace's airflow and heat exchanger inspected by a licensed technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057499980147,"sku":"GOODMAN-3150","price":12.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-adsh800403axab-10123530","provider":"National HVAC Parts","version":"1.0","type":"link"}
