The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control rated to trip at 150°F, engineered for the Amana/Goodman AMH951155DXAE furnace and compatible models. Mounted on the heat-exchanger partition, this snap-disc switch continuously monitors supply-air temperature and opens the control circuit if the plenum overheats — typically from restricted airflow, a dirty filter, or a failing blower. This protects the heat exchanger from thermal damage and cracking.

Specifications

Type: Primary high-limit switch (snap-disc)
Trip Temperature: 150°F (opens on rise)
Reset: Automatic (auto-reset on cool-down)
Configuration: Normally closed (NC)
Fit: Goodman / Amana AMH951155DXAE and compatible furnaces
OEM Part Number: 20162903

OEM vs. Generic

The OEM 20162903 guarantees the exact 150°F trip point, disc diameter, and mounting bracket for reliable protection. The generic equivalent is calibrated to the same trip temperature and fits the same footprint at a lower cost. Both are UL-recognized limit controls.

Installation Difficulty: Easy

A common DIY-friendly furnace repair. Turn off power, note the two wire connections, remove the mounting screws, transfer the spade terminals, and remount the new switch. Around 10–15 minutes. Note that frequent limit tripping usually points to an airflow problem — check the filter and blower before assuming the switch itself has failed.
