The Goodman 20162904 Primary Limit Temperature Control is the genuine OEM main high-limit for AMVC80805DXBD two-stage variable-speed gas furnaces. Mounted on the heat exchanger bulkhead, this auto-reset control constantly monitors supply-air temperature. If airflow drops — a clogged filter, failing blower, or closed registers — it opens the circuit and shuts off the burners before the furnace overheats, then automatically closes once temperatures return to normal. A furnace that short-cycles on heat, blows cool air, or throws a limit-open fault code often needs this part.

Specifications

Part Number: 20162904
Type: Primary limit / auto-reset temperature control
Action: Normally closed, opens on temperature rise
Reset: Automatic
Mounting: Factory bracket with spade terminals
Fits: AMVC80805DXBD and compatible Goodman/Amana 80% AFUE furnaces

OEM vs. Generic

The primary limit is calibrated to a model-specific trip point and mounts in an exact location on the exchanger. A generic substitute with a different setpoint or footprint can nuisance-trip or leave the furnace unprotected. This OEM Goodman control delivers the precise factory trip temperature and bolt pattern for correct, reliable protection.

Install Difficulty

Easy to moderate. Cut power, photograph the wiring, unplug the terminals, remove two screws, and mount the new control in the same orientation. If it trips again after replacement, correct the underlying airflow restriction rather than bypassing the safety.
