The Goodman 20162901 Primary Limit Switch is the OEM high-limit safety control for the Goodman VCES960603BNAA gas furnace and matching Amana/Goodman multi-position models. This temperature-sensing switch protects the heat exchanger by cutting power to the burners if the plenum overheats, preventing cracked heat exchangers and unsafe operation. It is a direct, exact-fit replacement for the factory-installed primary limit.
The OEM 20162901 is calibrated to the exact trip temperature specified by Goodman for this furnace, ensuring correct safety limits and preserving warranty compliance. Our generic equivalent meets the same trip range and physical footprint at a lower price point — ideal for out-of-warranty repairs where budget matters. Both are UL-recognized safety controls.
Easy (2/5). Turn off power and gas, remove the two mounting screws, transfer the wire leads one at a time, and reinstall. Most DIYers complete this in 15–20 minutes with a nut driver. Always verify furnace operation and limit trip after replacement.
