The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for AMH80604BNBD gas furnaces and related Goodman/Amana models. Mounted on the heat-exchanger bulkhead, this auto-reset control continuously monitors supply-air temperature and cuts power to the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. It is the primary defense against a cracked heat exchanger and overheating damage.

OEM vs. Generic

This OEM Goodman limit control is factory-calibrated to the precise trip temperature and insertion depth for your model. Generic replacements often differ in trip point or probe length, leading to nuisance lockouts or inadequate protection. On the primary safety limit, we strongly recommend genuine OEM.

Install Difficulty

Easy (2/5). Turn off power, disconnect the wire leads, remove the two mounting screws, and install the new control in the same position and orientation. Typically 15–20 minutes with a nut driver. Restore power and confirm a full, normal heating cycle after install.
