Mounted on the heat-exchanger\/plenum, this primary limit continuously senses supply-air temperature and opens the gas\/ignition circuit if the furnace overheats — the main over-temperature safety that protects the heat exchanger and blower assembly. A failed or drifting primary limit is a common cause of short-cycling, no-heat, and safety lockouts.\u003c\/p\u003e\u003cul\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 Normally closed; opens on over-temperature, recloses when cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensing:\u003c\/strong\u003e Bimetal disc calibrated to factory trip temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Quick-connect spade terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GME950403BXAB and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM 20162904 is matched to the precise cut-out and cut-in temperatures this furnace was certified with. Generic limits with a different set point can nuisance-trip on normal cycles or, worse, fail to protect the heat exchanger. Because this is the furnace's primary safety limit, genuine Goodman OEM is strongly recommended.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy–Moderate (2 of 5). Disconnect power, note wire positions, remove the two mounting screws, transfer the spade connectors, and secure the new limit against the plenum surface. A multimeter confirms continuity at room temperature. Verify airflow (filter, blower) isn't the root cause before replacing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058108055923,"sku":"GOODMAN-11002","price":42.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-gme950403bxab-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
