It senses temperature at the heat exchanger\/burner area and interrupts power to the gas valve during an overheat condition, guarding against heat exchanger damage and unsafe firing. The manual reset requires deliberate re-engagement, so a fault condition is always brought to a technician's attention rather than cycling unnoticed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123519\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\u003eThis switch is factory-calibrated to Goodman's specified trip point.
