The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM safety switch engineered for the AMES961005CNAA 96% AFUE gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger bulkhead, this normally-closed high-limit switch continuously monitors supply-air temperature and interrupts the gas valve and ignition circuit if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe conditions. A failed or nuisance-tripping limit is one of the most common causes of intermittent no-heat and short-cycling faults.

Contacts: Normally closed, opens on temperature rise
Fits: Goodman / Amana AMES961005CNAA and select 96% furnaces

OEM vs. Generic

The OEM 20162904 is factory-calibrated to the exact trip temperature specified for this furnace, ensuring correct safety operation and preserving your equipment warranty. Our Generic equivalent meets the same electrical and temperature ratings at a lower price point — ideal for out-of-warranty repairs where budget matters. Both are direct plug-in replacements requiring no rewiring.

Installation

Difficulty: Easy (1/5). Shut off power and gas, remove the two mounting screws, transfer the wire connectors to the new limit, and reinstall. Typical replacement time is 10–15 minutes with basic hand tools. Always verify the limit opens and resets correctly before returning the unit to service.
