This normally-closed thermal switch opens the control circuit if it senses an over-temperature or flame-rollout condition, shutting down the burners to prevent overheating. Once tripped, it must be manually reset by pressing the button — a deliberate design that flags a fault (such as restricted airflow or a blocked flue) rather than allowing automatic restarts.\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\u003eContacts: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90453BXAB and related GKS90-series furnaces\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (90%+ AFUE)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123533\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman switch is factory-calibrated to the exact trip temperature specified for the GKS90 heat exchanger and burner assembly. Generic switches with a different set point can trip too early (nuisance lockouts) or too late (unsafe operation). For a life-safety component, always match the OEM part and rating.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e Disconnect power, note and transfer the two spade wire connections, remove the mounting screws, and install the new switch in the same orientation. Typically a 10–15 minute repair. If the switch keeps tripping after replacement, diagnose the underlying airflow or venting cause before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058085544307,"sku":"GOODMAN-10532","price":9.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-high-limit-switch-for-gks90453bxab-10123533","provider":"National HVAC Parts","version":"1.0","type":"link"}
