Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary limit switch engineered for the AMVC80603BNBD gas furnace and compatible Amana/Goodman 80% AFUE models. This safety control monitors supply-air temperature and opens the ignition circuit if the heat exchanger overheats — protecting your furnace and home from unsafe conditions. Replacing a faulty limit switch restores reliable, code-compliant operation.

Specifications

Type: Primary high-limit safety switch
Trip point: 150°F (auto-reset)
Mounting: Manifold/heat-exchanger flange mount
Fits: AMVC80603BNBD and related Goodman/Amana furnaces
OEM Part Number: 20162903

OEM vs. Generic

This is a factory-original Goodman component with a calibrated trip temperature and exact bracket geometry — no drilling or adapting required. Generic universal limit switches often require rewiring and may trip at the wrong setpoint, causing nuisance shutdowns or unsafe operation. For a safety-critical part, OEM is the recommended choice.

Install Difficulty

Easy (2/5). Two-wire connection and a couple of mounting screws. Always shut off power and gas before servicing. Roughly 15–20 minutes for a DIY-capable homeowner; professional installation recommended if you are unfamiliar with furnace safety controls.
