Mounted on the heat-exchanger bulkhead, the primary limit continuously senses supply-air temperature. It closes the gas valve if the plenum overheats — typically from restricted airflow, a dirty filter, or a failed blower — protecting the heat exchanger from cracking and preventing a fire hazard. It also coordinates blower operation on temperature.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eComponent Type: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas circuit on plenum over-temperature\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resets once temperature normalizes)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMVC800804CXAA and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe primary limit must trip at a factory-specified temperature matched to this furnace's cabinet and airflow design. The OEM 20162904 carries the correct set point and mounting footprint. A generic limit with a different cut-out temperature can either fail to protect the heat exchanger or short-cycle the furnace on the limit. For a heat-exchanger safety control, OEM is the right choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eDisconnect power and gas, unplug the wiring, remove the mounting screws, and install the new 20162904 in the identical position and orientation so the sensing element reads plenum temperature correctly. If the old limit was tripping, a technician should first correct the airflow restriction that caused the overheat.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057852465523,"sku":"GOODMAN-7964","price":49.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-control-for-amvc800804cxaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
