The Goodman 20162903 Primary Limit Switch is a genuine OEM safety control designed for AMS950905DXA gas furnaces and compatible Goodman/Amana models. This 150°F normally-closed limit switch monitors heat-exchanger temperature and opens the circuit to shut off the burners if the furnace overheats, protecting the equipment and your home from unsafe operating conditions.

A failed limit switch is one of the most common causes of a furnace that short-cycles, blows cold air, or locks out on a limit fault. Replacing it with the correct OEM-spec part restores proper safety cutout and normal heating operation.

  • Part Type: Primary high-limit safety switch
  • Trip Point: 150°F (opens on rise)
  • Action: Normally closed (auto-reset)
  • Fits: Goodman/Amana AMS950905DXA furnace
  • OEM Part #: 20162903

OEM vs. Generic: Our genuine OEM switch is calibrated to the exact 150°F trip point specified for this furnace. Generic universal limits often carry different trip temperatures and mounting profiles, which can cause nuisance lockouts or improper safety response. For a safety component, OEM is strongly recommended.

Install Difficulty: Easy (⭐⭐☆☆☆). Two-wire connection and screw-mount to the heat exchanger. Always shut off power and gas before servicing. If unsure, consult a licensed HVAC technician.
