This limit switch monitors heat exchanger and burner-area temperature and cuts power to the gas valve if the furnace overheats — protecting against cracked heat exchangers and unsafe operation. Its manual reset design requires a technician to physically reset it, ensuring an overheat event is never silently ignored.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GCH90703BXAB (Goodman 90%+ gas furnace)\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature shutoff for gas valve\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman limit switches are calibrated to the exact trip temperature the furnace was engineered for.
