This temperature-activated safety control opens the ignition circuit if the heat exchanger or blower compartment overheats, shutting the furnace down to prevent damage and fire hazards. It requires a manual reset after tripping, alerting the homeowner to an underlying airflow or overheating problem.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123518\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens circuit on overtemperature; requires manual reset\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMV950453BXA and related furnace models\u003c\/li\u003e\n\u003cli\u003eApplication: Heat exchanger \/ blower overheat protection\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 genuine 10123518 carries Goodman's exact rating and mounting geometry, so it protects the furnace at the correct threshold. A generic switch with a different set point can nuisance-trip or, worse, fail to shut the unit down.
