This high-limit switch protects your furnace by interrupting the gas valve and ignition circuit if the heat exchanger reaches an unsafe temperature, preventing overheating, cracked heat exchangers, and potential fire hazards. As a manual reset device, it must be physically reset after a trip — an intentional safety feature that flags a recurring airflow or overheating problem before it escalates.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature furnace safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ACES800603ANAA and compatible furnace models\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e part — calibrated to the exact trip temperature your furnace was engineered for.
