Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control designed as a direct-fit replacement for the AMS80604BXAC gas furnace and compatible Goodman/Amana models. This safety component continuously monitors heat-exchanger temperature and shuts off the burners if the furnace overheats, protecting the equipment and your home from unsafe operating conditions.

Specifications

Part type: Primary high-limit temperature control (auto-reset)
Brand: Goodman OEM
Compatible model: AMS80604BXAC and related 80% AFUE furnaces
Function: Overheat safety cutoff for the heat exchanger
Equipment type: Gas furnace

OEM vs. Generic

The genuine OEM 20162904 is calibrated to Goodman's exact trip-point specification, ensuring proper safety response and code compliance. Aftermarket generics may vary in trip temperature and mounting fit, which can lead to nuisance lockouts or premature failure. For a critical safety control, we recommend the OEM part.

Installation Difficulty

Moderate — Replacement typically takes 20–30 minutes with basic hand tools. Because this is a gas-furnace safety control, always shut off power and gas before servicing. Professional installation is recommended if you are not comfortable working near the burner assembly.
