The Goodman 20162901 Primary Limit Switch is a genuine OEM high-temperature safety control engineered for the AMS80403AXAC 80% AFUE gas furnace and compatible Goodman and Amana models. Mounted on the heat exchanger bulkhead, this normally-closed thermal switch continuously monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe conditions.

Specifications

Type: Primary high-limit switch (auto-reset)
Fits: Goodman & Amana 80% single-stage gas furnaces, incl. AMS80403AXAC
OEM Part Number: 20162901
Function: Overheat protection / gas valve cutoff

OEM vs. Generic

This is a genuine Goodman OEM part calibrated to the exact trip temperature your furnace's control board expects. Generic aftermarket limits are often close but not identical, which can cause premature tripping or delayed shutoff. Choosing OEM guarantees correct temperature rating, terminal spacing, and mounting fit — no guesswork on a safety-critical component.

Installation Difficulty

Easy (1/5). Disconnect furnace power, remove two mounting screws, unplug the two spade terminals, and reverse to install the new switch. Most homeowners complete this in under 15 minutes with a nut driver. If the furnace is short-cycling on limit, also inspect airflow and the blower before replacing.

Backed by genuine OEM quality and shipped fast so your furnace is back in service quickly.
