This safety control monitors heat-exchanger temperature and opens the circuit to shut down the burners if the furnace overheats — protecting against blocked airflow, failed blowers, or restricted venting. Unlike auto-reset limits, the manual reset design requires a deliberate button press to restore operation, prompting a technician to diagnose the root cause of the overheat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003ePart Type: Manual Reset High-Limit Safety Switch\u003c\/li\u003e\n\u003cli\u003eCompatible Model: ACVC90905DXAB (90% AFUE furnace)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (also fits select Amana units)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ high-limit shutoff with manual reset button\u003c\/li\u003e\n\u003cli\u003eConnection: OEM spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 10123517 is calibrated to Goodman's exact trip and reset temperatures — a safety-critical spec.
