It opens the control circuit and shuts down the burners if the furnace overheats or a flame rollout is detected, protecting the heat exchanger and cabinet. Because it is a manual-reset device, it stays tripped until pressed — a deliberate safety feature that flags an underlying airflow or venting problem.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGoodman OEM part number: 10123533\u003c\/li\u003e\n\u003cli\u003eComponent: High-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eReset type: Manual (push-to-reset button)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (90%+ AFUE)\u003c\/li\u003e\n\u003cli\u003eFits model: GKS90905DXAD\u003c\/li\u003e\n\u003cli\u003eFit type: Direct exact-fit replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature. A generic switch with the wrong setpoint can either nuisance-trip or, worse, fail to open during a real overheat event. The OEM 10123533 carries Goodman's exact temperature rating and mounting footprint, so safety timing matches the furnace's certified design. OEM is strongly recommended for any safety limit.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Typically 10–20 minutes: power off the furnace, note wire positions, remove the two mounting screws, transfer the spade connectors to the new switch, and reinstall.
