Mounted on the heat exchanger bulkhead, it senses supply-air temperature and shuts off the burners if the furnace overheats due to restricted airflow, protecting the heat exchanger and preventing a hazardous condition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary (auto-reset) high-limit control\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air overtemperature cutout\u003c\/li\u003e\n\u003cli\u003eMounting: Heat-exchanger \/ blower bulkhead, factory footprint\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMEH960403BXAA and related 96% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is calibrated to the exact trip temperature engineered for this furnace. Because a primary limit is a life-safety device, \u003cstrong\u003egeneric\u003c\/strong\u003e substitutes with different set points can cause nuisance lockouts or, worse, fail to protect the heat exchanger.

Shut off gas and electrical power first. If the limit trips after replacement, diagnose airflow (dirty filter, blocked coil, or blower issues) rather than repeatedly resetting.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057588584819,"sku":"GOODMAN-4547","price":54.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-ameh960403bxaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
