Mounted on the heat-exchanger housing, this auto-reset high-limit switch protects the furnace from overheating by cutting the gas valve when supply-air temperature exceeds its factory set point — typically caused by a dirty filter, closed registers, or a failing blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary (main) high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMH950453BXAD and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003ePart number: 20162904 (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e carries the exact trip temperature, mounting flange, and terminal configuration matched to this furnace. A generic high-limit with a different set point can allow the heat exchanger to overheat or cause premature nuisance shutdowns.

Confirm proper airflow (filter, blower, ductwork) before returning the furnace to service, since restricted airflow is the most common cause of limit trips.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058111758707,"sku":"GOODMAN-11123","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-gmh950453bxad-furnace-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
