The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM safety switch for the Amana/Goodman AMEC800803BNAA gas furnace. Mounted on the heat exchanger area, this primary high-limit monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger and preventing unsafe operation. If your furnace short-cycles, trips on high limit, or won't fire, a failed limit control is a common cause.
This is a genuine OEM Goodman limit control factory-calibrated to the correct trip and reset temperatures for the AMEC800803BNAA. Generic snap-disc replacements may carry the wrong temperature rating, causing nuisance trips or, worse, failing to protect the heat exchanger. For a safety device, OEM is the recommended choice.
Easy to Moderate — typically a two-screw mount with quick-connect terminals. Turn off power before servicing and verify the temperature rating matches the original.
