The Goodman/Amana 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for AMEC960402BNAC gas furnaces and compatible Goodman and Amana equipment. Mounted on the heat exchanger or burner bulkhead, this auto-reset control continuously senses supply-air temperature and shuts down the burners if the furnace overheats — typically from a dirty filter, blocked ductwork, or a failed blower.

The primary limit is one of the furnace's most important safety devices. A control that has drifted out of calibration or failed open causes short cycling, no-heat conditions, or a burner that fires but never runs a full heating cycle. Installing the correct OEM-calibrated limit restores reliable, safe operation.

Type: Primary high-limit temperature control (auto reset)
Contacts: Normally closed, opens on temperature rise
Function: Over-temperature shutdown of burners / gas valve
Sensing: Supply-air / heat exchanger temperature
Fits: Amana AMEC960402BNAC and select Goodman/Amana gas furnaces
OEM Part #: 20162904

OEM vs. Generic: The trip and reset temperatures on this limit are matched to the furnace's heat-exchanger design. Our OEM 20162904 arrives pre-calibrated to those exact set points. Generic limits often use different temperatures or insertion depths, causing nuisance lockouts or unsafe operation. OEM is the recommended choice for this safety control.

Install Difficulty: Easy to Moderate (⭐⭐☆☆☆). Disconnect power, remove two mounting screws and the wire connectors, then transfer to the new control. If the old limit tripped, correct airflow restrictions before returning the furnace to service.
