The Goodman 20162903 Primary Limit Switch is a factory-original safety control engineered for the GMS950905DXA gas furnace and other compatible Goodman/Amana models. This 150°F auto-reset thermal limit monitors heat-exchanger temperature and interrupts the burner circuit if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operating conditions.

Specifications

Part number: 20162903
Type: Primary high-limit switch (auto-reset)
Trip point: 150°F open on rise
Equipment: Gas furnace
Fits: Goodman GMS950905DXA and compatible units
Brand: Goodman OEM

OEM vs. Generic

Our OEM Goodman option is the exact factory part — identical trip temperature, mounting footprint, and terminal spacing for a true plug-and-play replacement. The generic alternative meets the same 150°F specification at a lower price point and is a great choice for budget-conscious repairs where an exact OEM match isn't required. Both restore proper high-limit protection.

Installation Difficulty

Easy (1 of 5). Replacement typically takes 10–15 minutes with a nut driver. Always disconnect power at the furnace before servicing. Note terminal orientation, remove the two mounting screws, transfer the wires, and reinstall. If your furnace short-cycles or locks out on limit after replacement, inspect airflow and the blower before condemning other components.

Keep your Goodman furnace running safely through every heating season with a genuine 20162903 limit switch.
