This high-limit switch monitors heat-exchanger and plenum temperature and cuts power to the gas valve if the furnace overheats — protecting against blocked airflow, a failed blower, or a dirty filter. As a manual-reset device, it must be physically reset after a trip, alerting the homeowner that a fault occurred.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GDH80403AXBD and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual (push-button)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical:\u003c\/strong\u003e Normally closed, opens on temperature rise\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine Goodman switch is calibrated to the exact trip and reset temperatures specified for this furnace platform.

De-energize the furnace, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. No calibration needed.
