Mounted on the heat-exchanger bulkhead, it continuously monitors supply-air temperature and shuts down the burners if the furnace exceeds its safe operating limit — the front-line defense against overheating from restricted airflow, a stuck blower, or a clogged filter. Unlike a manual-reset rollout switch, the primary limit is an automatic-reset control that re-closes once temperatures return to normal.\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\u003eNormally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated trip and reset set points\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement for part 20162904\u003c\/li\u003e\n\u003cli\u003eFits AMES800604BXAA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe primary limit is a critical safety device, and its trip point must match the furnace's engineered airflow and temperature-rise range. The genuine OEM 20162904 arrives calibrated to Goodman's exact specification. Generic universal limits with adjustable or approximate set points risk nuisance shutdowns or inadequate protection of the heat exchanger — not worth the small savings on a safety control.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e The control mounts with two screws and connects via two spade terminals — most replacements take 15 to 25 minutes. Cut power at the disconnect before servicing, and address any airflow restriction that may have caused the original limit to open. When in doubt, use a licensed HVAC professional.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057590845811,"sku":"GOODMAN-4627","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-ames800604bxaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
