Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control designed for the AMS80604BXAD gas furnace and compatible Goodman/Amana models. This safety switch monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow, blower failure, or a dirty filter. A failed limit control can cause short-cycling, no-heat conditions, or, if bypassed, a genuine safety hazard.

Specifications

OEM Part Number: 20162904
Function: Primary high-limit safety cutout
Type: Automatic-reset temperature control
Compatibility: Goodman/Amana AMS80604BXAD and related 80% furnaces
Mounting: Factory-matched flange and trip temperature

OEM vs. Generic

This genuine OEM limit is calibrated to the exact trip temperature specified for your furnace's heat exchanger. Generic limits may trip at the wrong setpoint, causing nuisance shutdowns or failing to protect the appliance. OEM ensures the correct cutout temperature, mounting footprint, and terminal layout.

Installation Difficulty

Easy to Moderate — disconnect power, remove two mounting screws and the wire connectors, and swap the switch. Verify orientation and terminal wiring. A basic DIYer can complete it; when in doubt, use a licensed technician.

Replace with the authentic Goodman 20162904 to restore safe, reliable furnace operation.
