Mounted on the heat exchanger bulkhead, this high-limit switch continuously monitors supply-air temperature and opens the control circuit to shut off the burners if the furnace overheats — typically caused by a dirty filter, blower failure, or restricted airflow. It is an auto-reset device that closes again once temperatures return to a safe range, and it is essential to safe furnace operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air overheat protection\u003c\/li\u003e\n\u003cli\u003eFits: Goodman VMS80603AXAA and compatible furnace models\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM Goodman 20162904 is factory-set to the exact open\/close temperature and insertion depth this furnace requires. A universal limit control with the wrong trip point or probe length can cause repeated nuisance shutdowns or allow the furnace to run past safe temperatures.
