This safety control monitors heat-exchanger temperature and opens the circuit to shut down the burners if the furnace overheats — protecting against fire and heat-exchanger damage. Its manual reset button ensures the unit will not automatically restart after a trip, so the underlying cause (blocked airflow, failed blower, dirty filter) is investigated before the furnace runs again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123538\u003c\/li\u003e\n\u003cli\u003ePart Type: Manual reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eCompatible Equipment: AMES920403ANAA gas furnace\u003c\/li\u003e\n\u003cli\u003eFit: Exact OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman 10123538 is calibrated to the exact trip temperature specified for the AMES920403ANAA. Because this is a life-safety component, using the correctly rated OEM switch is critical — a generic switch with the wrong trip point can either nuisance-trip or, worse, fail to protect the furnace. Do not substitute an auto-reset switch for this manual-reset control.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate.\u003c\/strong\u003e Typically a two-screw, two-wire swap on the burner box; 15–20 minutes with basic tools.
