Acting as a temperature safety cutout, it interrupts the burner circuit when heat-exchanger temperatures climb past the rated threshold — typically from blocked airflow, a dirty filter, or a failed blower. The manual-reset button ensures the furnace won't silently resume after an overheat event, prompting the homeowner or tech to investigate.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123534\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCH90905DXAB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit thermal cutout\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemp\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e switch is calibrated to the precise trip temperature and fits the factory bracket without modification.
