It functions as a temperature-activated safety control, opening the circuit to shut down burner operation whenever compartment or heat-exchanger temperatures exceed the furnace's rated limit. This protects the heat exchanger from cracking and prevents dangerous flame-rollout conditions. As a manual-reset switch, it will not auto-restart — it must be reset by hand once the overheat cause is corrected, ensuring problems are addressed rather than ignored.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123519\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana compatible)\u003c\/li\u003e\n\u003cli\u003ePrimary Fit: GCH91155DXAA gas furnace\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat and flame-rollout shutdown\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eChoosing the \u003cstrong\u003eOEM 10123519\u003c\/strong\u003e guarantees the correct trip point, terminal layout, and mounting footprint for your furnace.
