OEM Goodman 20162904 Primary Limit Temperature Control

Genuine Goodman/Amana 20162904 primary limit temperature control is a direct-fit high-limit safety device for the AMEH961005DXAA gas furnace and compatible Goodman and Amana models. Mounted on the heat-exchanger bulkhead, it continuously senses supply-air temperature and de-energizes the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure.

Specifications

Type: Primary (auto-reset) high-limit temperature control
Function: Supply-air over-temperature protection
Mounting: Bulkhead / heat-exchanger plate
Fits: AMEH961005DXAA and compatible Goodman/Amana furnaces
OEM Part Number: 20162904

OEM vs. Generic

The OEM 20162904 is factory-calibrated to the exact opening and closing temperatures Goodman specifies for this model, and its sensing element length matches the airflow path. Substituting a generic limit with a different set point can cause short-cycling or, worse, fail to protect the heat exchanger. OEM is the safe choice for this control.

Installation Difficulty

Moderate (2 of 5). Requires removing the burner/control panel, disconnecting two low-voltage leads, and unfastening the mounting screws. Shut off power and gas first. Correct any airflow restriction before assuming the limit itself has failed.
