Mounted on the heat-exchanger vestibule, this auto-reset control continuously senses supply-air temperature. If the furnace overheats — commonly from a dirty filter, blocked ducts, or a failing blower — the primary limit opens the gas valve circuit to shut down the burners, then automatically closes and allows ignition once the temperature returns to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMVC81155CXAB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e primary limit is factory-calibrated to the precise open\/close set points for this furnace and mounts to the exact bracket footprint. Generic replacements may differ in trip temperature or mounting hole pattern, leading to nuisance lockouts or improper protection.

Before replacing the limit, verify airflow is not restricted so the new switch does not trip for the same reason.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057876713843,"sku":"GOODMAN-8647","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-amvc81155cxab-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
