Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary limit temperature control designed for the AMVC800803BNAA gas furnace and other compatible Goodman and Amana models. This high-limit safety switch monitors the temperature in the heat exchanger compartment and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing an unsafe operating condition. If your furnace short-cycles on heat, trips out mid-cycle, or fails to fire, a failed primary limit is a common cause.

OEM vs. Generic

This OEM Goodman limit control is calibrated to the exact cut-out temperature specified for the AMVC800803BNAA heat exchanger. A generic limit with a different trip point can allow overheating or cause premature nuisance trips. Choosing the OEM part ensures the safety circuit behaves exactly as the furnace was engineered to — the smart choice for a component that protects the most expensive part of your system.

Install Difficulty

Easy to Moderate. Turn off power to the furnace, remove the mounting screws, unplug the two spade terminals, and install the replacement in the same orientation. No calibration is required. Verify the furnace completes a full heat cycle after installation.
