Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control that monitors supply-air temperature over the heat exchanger and shuts off the gas valve if the furnace overheats — typically caused by restricted airflow, a dirty filter, or a failed blower. It is a direct-fit replacement for the AMSS960803BNAA and related Goodman/Amana 96% AFUE furnaces, and is one of the most important safety controls in the appliance.

Specifications

Part Type: Primary limit / high-limit temperature control
Function: De-energizes gas valve on plenum over-temperature
Reset: Automatic (temperature-sensing bimetal)
Fits: Goodman & Amana furnaces incl. AMSS960803BNAA
OEM Part #: 20162904

OEM vs. Generic

The primary limit's trip point and mounting insertion depth are matched to this specific heat exchanger. A generic or mismatched control can trip early (short-cycling, no heat) or trip late (safety risk). The authentic Goodman part guarantees the factory setpoint and correct probe length.

Installation Difficulty

Moderate (3/5) — power off at the disconnect, remove the burner/blower panel, unplug the wiring, unscrew the limit from the partition, and install the new one at the same depth. 20–30 minutes; verify heat cycle after replacement.
