This automatic-reset thermal limit continuously monitors heat-exchanger and plenum temperature, cutting power to the gas valve if the furnace overheats due to restricted airflow, a dirty filter, or a failed blower — protecting the heat exchanger from cracking and preventing unsafe operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Primary high-limit temperature control (automatic reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overtemperature safety cutout for the gas valve circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e AMES800603AXAA and compatible Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Snap-mount to heat-exchanger bulkhead, spade terminal connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Direct-replacement OEM component\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 20162904 is calibrated to the exact trip and reset temperatures specified by Goodman for this furnace, ensuring the safety circuit behaves as the equipment was certified. Universal or generic limit switches often carry approximate trip points that can cause nuisance lockouts or, worse, delayed cutout. For a safety-critical control we strongly recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — Requires shutting off gas and power, removing the burner-compartment panel, transferring the two spade connectors, and confirming correct orientation. A knowledgeable DIYer can complete it in about 30 minutes; if you are unsure about a furnace safety control, use a licensed HVAC technician. Always cycle the furnace and verify normal shutoff after replacement.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057590321523,"sku":"GOODMAN-4605","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-ames800603axaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
