The Goodman/Amana 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch built for the AMES961205DNAA gas furnace. Mounted on the heat exchanger, it monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger and preventing hazardous conditions. If your furnace short-cycles, trips on limit, or fails to fire, a faulty primary limit is a common cause.

OEM vs. Generic

The OEM 20162904 is factory-calibrated to the exact trip temperature Goodman specifies for this furnace's heat exchanger. Generic limits with incorrect cut-out points can either nuisance-trip or fail to protect the unit. Because this is a life-safety component, the genuine OEM part is the recommended choice.

Installation Difficulty

Easy to Moderate — Two mounting screws and a pair of quick-connect terminals. Always disconnect power before servicing. If the original limit tripped, have a technician diagnose the underlying overheating cause (dirty filter, blower fault, or restricted airflow).
