The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control rated to open at 150°F, built for the Goodman/Amana AKSS920703BXAA gas furnace and compatible models. Mounted to the heat-exchanger vestibule, it monitors supply-air temperature and cuts the gas valve if airflow is lost or restricted (dirty filter, failed blower, closed registers), protecting the heat exchanger from overheating. It automatically resets once temperature returns to a safe range.

Specifications

Type: Primary high-limit switch, auto-reset
Trip point: 150°F (opens on temperature rise)
Circuit: Normally closed
Fit: Goodman & Amana gas furnaces incl. AKSS920703BXAA
OEM Part Number: 20162903

OEM vs. Generic

The 150°F trip point is model-specific. This genuine OEM switch matches your furnace's designed limit exactly. A generic switch with a different setpoint or mounting bracket can cause nuisance lockouts or fail to protect the heat exchanger — not worth the risk on a safety device.

Installation Difficulty

Easy — Usually two screws and two spade terminals. Disconnect power first. If the old limit was tripping, correct the underlying airflow problem (replace the filter, check the blower and ductwork) before restoring the furnace to service.
