This temperature-activated control protects the heat exchanger and surrounding cabinet by interrupting the gas valve and burner circuit if the furnace overheats — typically from restricted airflow, a failed blower, or a flame rollout condition. Because it is a manual reset device, it requires a deliberate button press to restore operation, alerting the homeowner that a fault occurred.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens on over-temperature to shut down heating\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: ACV90905DXBB\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature. The \u003cstrong\u003egenuine OEM 10123517\u003c\/strong\u003e opens at the exact factory setpoint for this furnace; a generic switch with the wrong rating can nuisance-trip or, worse, fail to protect the heat exchanger.
