Goodman 20162904 Primary Limit Temperature Control

The 20162904 is a genuine OEM primary limit temperature control for Goodman and Amana gas furnaces, including the AMVC80805DXCA. Mounted on the heat exchanger bulkhead, this control continuously monitors supply-air temperature and opens the burner circuit if the furnace overheats — protecting the heat exchanger and blower compartment from heat damage caused by restricted airflow or blower failure.

Specifications

Type: Primary high-limit temperature control (auto reset)
Function: Normally closed; opens on over-temperature
Sensing: Supply-air / heat exchanger bulkhead mount
Fits: Goodman & Amana 80% multi-speed furnaces (AMVC80805DXCA and related)
Genuine OEM replacement

OEM vs. Generic

The OEM 20162904 is calibrated to the furnace's exact trip temperature and uses the correct mounting bracket and insertion depth. Generic limits with different set points or probe lengths can nuisance-trip in heat mode or fail to protect the unit. As a safety control, OEM is the recommended choice.

Install Difficulty

Moderate (3/5). Power off, remove the burner/control panel, unscrew the mounting bracket, transfer wiring to the new control, and confirm proper seating. About 30–40 minutes; verify furnace cycles and limits correctly after install.
