Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F for the AKSS920905DXAA gas furnace and compatible Goodman and Amana models. Mounted on the heat-exchanger/plenum, this control continuously monitors supply-air temperature and shuts down the burners if the furnace overheats due to restricted airflow, a dirty filter, or blower failure. Unlike a manual-reset limit, the primary limit typically auto-resets once temperatures return to a safe range, allowing normal operation to resume.

Specifications

Type: Primary high-limit safety switch
Trip Temperature: 150°F
Function: De-energizes burners on plenum overheat
Mounting: Heat-exchanger / supply-air plenum
Compatibility: Goodman / Amana AKSS920905DXAA and related furnaces
OEM Part Number: 20162903

OEM vs. Generic

The OEM 20162903 is calibrated to Goodman's exact 150°F trip point with the correct probe length and mounting flange for a true drop-in replacement. A Generic equivalent can lower cost while matching the same 150°F rating, but confirm the probe/flange dimensions before ordering. For a temperature-critical safety limit, OEM ensures the furnace protects itself at the intended threshold.

Installation Difficulty

Easy (2/5). Turn off power, open the blower/heat-exchanger panel, disconnect the terminals, remove the two mounting screws, and install the new switch in the same position. About 10–15 minutes with basic tools. If the old limit tripped repeatedly, check the filter, blower, and ductwork for airflow restrictions before finishing.
