The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for Goodman and Amana gas furnaces, including the AMVC800805DNAA. Mounted on the heat-exchanger/blower deck, it monitors supply-air temperature and shuts down the burners if the furnace overheats due to restricted airflow — protecting the heat exchanger from cracking.

Specifications

OEM Part Number: 20162904
Part Type: Primary high-limit temperature control
Reset: Automatic (opens on high temp, recloses when cooled)
Compatible Model: AMVC800805DNAA (Amana 80% AFUE variable-speed furnace)
Function: Normally-closed thermal limit, factory-calibrated trip point

OEM vs. Generic

The OEM 20162904 carries the exact trip and reset temperatures matched to this furnace's heat-exchanger design and blower deck. Generic limit controls with a different set point or probe length can nuisance-trip on normal cycles or fail to protect the heat exchanger. Because this guards against heat-exchanger failure and CO exposure, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Shut off power, remove the blower-compartment panel, unplug the wiring harness, remove the two mounting screws, and transfer the new control. 20–30 minutes. Frequent tripping usually indicates a dirty filter, closed registers, or a failing blower — diagnose the airflow cause, don't just replace the switch.
