This temperature-sensing safety control monitors heat exchanger and plenum temperatures and cuts power to the gas valve if the furnace overheats — protecting against fire and heat-exchanger damage. Unlike auto-reset limits, the manual reset design requires a physical button press to restore operation after a trip, ensuring an overheat condition is investigated before the furnace runs again. A failed or nuisance-tripping limit switch causes no-heat calls and intermittent shutdowns.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 10123533\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GKS90904CXAC furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Shuts off gas valve on overheat; requires manual reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Push-button manual reset\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 10123533 is calibrated to the exact trip temperature specified for your furnace model, so it protects without nuisance tripping. Generic limit switches with incorrect temperature ratings can trip early (short cycling) or too late (defeating the safety function). For a safety-critical control, the OEM part is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — About 20–30 minutes. Turn off power and gas, remove the two mounting screws and disconnect the wiring from the old switch, then mount the new limit and reconnect the leads. Because this is a safety control, verify correct operation and trip response; professional installation is recommended.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058095833459,"sku":"GOODMAN-10769","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-gks90904cxac-10123533","provider":"National HVAC Parts","version":"1.0","type":"link"}
