Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch with a 150°F trip point, designed for the AMH950704CXAC gas furnace and compatible Goodman and Amana models. Mounted on the heat exchanger or blower deck, this auto-reset control monitors supply-air temperature and de-energizes the burners if airflow is restricted and the furnace overheats — protecting the heat exchanger from thermal damage while allowing the blower to run and cool the cabinet. It automatically closes again once temperatures return to normal.

Specifications

  • Type: Primary high-limit switch
  • Trip temperature: 150°F (opens on rise)
  • Reset: Automatic
  • Function: Over-temperature / airflow-loss safety cutoff
  • Connection: 1/4" spade terminals
  • Fits: AMH950704CXAC and compatible Goodman/Amana furnaces
  • OEM Part Number: 20162903

OEM vs. Generic

The OEM Goodman 20162903 guarantees the precise 150°F trip point and bracket geometry your furnace requires — essential for a safety control. Generic equivalents exist at lower cost and can work if the temperature rating and mount match exactly, but always verify the °F spec before installing. For high-limit protection, OEM is the recommended choice.

Installation Difficulty

Easy (2/5). Power down the furnace, note wire positions, remove the mounting screws, transfer the leads to the new switch, and remount. A 15-minute job for a confident DIYer. If the limit keeps tripping, have a technician check airflow and the blower.
