The genuine OEM Goodman 20162904 Primary Limit Temperature Control is the main high-limit safety and temperature-sensing control for the Amana/Goodman AMVC80804CXBD 80,000 BTU variable-speed gas furnace. Mounted on the heat exchanger bulkhead, it continuously monitors supply-air temperature and opens the gas valve circuit if the furnace exceeds its safe operating limit — protecting the heat exchanger, wiring, and cabinet from heat damage caused by restricted airflow, a dirty filter, or blower failure.

Specifications

Type: Primary limit / high-temperature control
Reset: Automatic (snap-disc)
Fits: Goodman/Amana AMVC80804CXBD variable-speed furnace
Mounting: Factory bulkhead bracket
Terminals: Quick-connect spade

OEM vs. Generic

The primary limit is calibrated to a precise trip temperature matched to this furnace's heat exchanger. A generic control with a different set point can cause repeated short-cycling lockouts or allow unsafe over-temperature operation. This safety-critical part should always be replaced with the factory-original Goodman control.

Installation Difficulty

Moderate. Turn off power, remove the control panel, unscrew the limit from its bracket, transfer the wire leads, and reinstall. Typically 20–30 minutes for a competent DIYer. If the old limit was tripping, correct the underlying airflow issue before returning the furnace to service.
