The Goodman 20162904 Primary Limit Temperature Control is the genuine OEM high-limit safety switch for the AMH80804BNBA 80,000 BTU gas furnace and other compatible Goodman and Amana models. This automatic-reset limit switch continuously monitors heat-exchanger temperature and shuts off the burners if the furnace overheats, protecting your equipment and home from unsafe conditions. A failed primary limit is a leading cause of short-cycling, no-heat calls, and lockout codes.

OEM vs. Generic

This is a factory-original OEM part built to the exact trip temperature and dimensional spec of your furnace. Generic universal limits are often available for less, but require verifying the correct set-point and terminal orientation. Choosing OEM guarantees the correct temperature calibration and a drop-in fit — no guesswork on a safety-critical component.

Installation Difficulty

Moderate — Two mounting screws and two spade terminals. Always cut power at the disconnect before servicing. If you are unsure about wiring or your furnace remains in lockout after replacement, consult a licensed HVAC technician.
