Mounted on the heat-exchanger\/blower partition, this auto-reset high-limit senses supply-air temperature and interrupts the gas valve if airflow is lost or the furnace overheats — protecting the heat exchanger from cracking. A failed primary limit is a frequent cause of short-cycling and no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Shuts off heating on overheat \/ loss of airflow\u003c\/li\u003e\n\u003cli\u003eAction: Bimetal snap-disc, model-specific trip temperature\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (80% AFUE class)\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162904\u003c\/li\u003e\n\u003cli\u003eFits model: AMH80804BNBB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is matched to the precise trip and reset temperatures Goodman engineered for this furnace's heat exchanger and blower table. Because trip point varies by furnace, a generic limit with an incorrect set-point can cause nuisance short-cycling or, worse, fail to protect against a real overheat. For this critical safety control, the OEM part is the correct and code-appropriate choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate (2\/5).\u003c\/strong\u003e Disconnect power, transfer the two wire leads, remove the mounting screws, and install the replacement in the identical location and orientation so the sensing element sits in the airstream. Basic hand tools and a nut driver required. Typical time: 15–25 minutes.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eNever bypass a limit control. Shut off power and gas before servicing; if the furnace continues to trip, have a licensed HVAC technician inspect airflow and the heat exchanger.\u003c\/em\u003e\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057620599155,"sku":"GOODMAN-5529","price":69.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-amh80804bnbb-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
