Mounted on the heat-exchanger bulkhead, it monitors plenum temperature and cuts power to the gas valve if the furnace overheats — protecting against a cracked heat exchanger, blower failure, or restricted airflow. If your furnace short-cycles on heat, trips out, or won't fire, a failed primary limit is a common culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens the gas-valve circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman WGFM195090S4CAC and related 95% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Safety \/ limit control\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine 20162904 is calibrated to this furnace's exact trip temperature and mounting footprint. Generic limits with the wrong set point either trip prematurely (nuisance shutdowns) or fail to trip when they should — a serious safety risk. Because this is a life-safety component, we strongly recommend the factory OEM control.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation difficulty:\u003c\/strong\u003e Moderate. Turn off power and gas, note the wire positions, unbolt the old limit from the heat-exchanger plate, and mount the new one in the same orientation. Verify correct seating against the bulkhead so it reads plenum temperature accurately. HVAC-technician installation is recommended for safety verification.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058237489523,"sku":"GOODMAN-14352","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-wgfm195090s4cac-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
