Mounted on the heat exchanger bulkhead, the primary limit monitors supply-air temperature and opens the gas\/ignition circuit if the furnace overheats — typically caused by restricted airflow such as a dirty filter, blocked returns, or a failing blower. This auto-reset control closes again once temperatures return to normal, protecting the heat exchanger from thermal damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed (opens on high temperature)\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eMounting: OEM bulkhead \/ snap-disc bracket fit\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS80604BXAA and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman limit control\u003c\/strong\u003e is set to the exact trip temperature and insertion depth engineered for this cabinet, so it protects the furnace without shutting down prematurely. Generic snap-discs may share a rating but differ in probe length and calibration. Because this is a primary safety device, the OEM part is the recommended choice.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e The control is retained by two screws and quick-connect terminals. Shut off power and gas, photograph the wiring, and install the new control in the same orientation and depth. Estimated time: 15–25 minutes. If the limit trips repeatedly, correct the airflow restriction rather than replacing the part alone.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057687544179,"sku":"GOODMAN-6823","price":54.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-control-for-ams80604bxaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
