This safety switch monitors heat-exchanger temperature and cuts power to the gas valve if the furnace overheats — typically due to restricted airflow, a dirty filter, or a failing blower. A tripped or failed limit control is a common cause of short-cycling and no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003ePart number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ high-temperature safety cutoff\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace heat-exchanger section\u003c\/li\u003e\n\u003cli\u003eFits: GKS90453BXAE and compatible Goodman\/Amana models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature and mounting geometry.
