OEM Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F, designed for the AMH950905DXAE gas furnace and compatible Goodman and Amana models. As the furnace's primary temperature limit, it continuously monitors the heat exchanger/plenum temperature and de-energizes the gas valve if the air temperature exceeds its rating — typically caused by restricted airflow such as a dirty filter or failed blower. This protects the heat exchanger from thermal damage and prevents unsafe overheating.

Specifications

Part Number: 20162903
Type: Primary high-limit switch
Trip Temperature: 150°F
Reset: Automatic (temperature-based)
Function: Overtemperature / airflow-failure safety cutout
Brand: Goodman / Amana (OEM)
Fits Model: AMH950905DXAE and compatible furnaces

OEM vs. Generic

This genuine OEM 150°F limit is calibrated to the exact trip point and mounting geometry your furnace requires. Generic switches with approximate ratings can cause short-cycling on limit or fail to protect the heat exchanger. For accurate temperature protection, OEM is the reliable choice.

Installation Difficulty

Easy (1 of 3). Disconnect power, remove the two mounting screws, transfer the wiring, and reinstall. If the limit keeps tripping, check the filter and blower before assuming the switch has failed.
