Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary limit temperature control for the AMVM971205DNBA modulating gas furnace and compatible Goodman/Amana AMVM97 units. Mounted on the heat-exchanger or blower deck, this primary high-limit switch continuously monitors supply-air temperature. If airflow is lost or the furnace overheats, it opens the circuit to shut down the gas valve, protecting the heat exchanger from thermal damage — then automatically resets once temperatures return to a safe range.

Specifications

OEM Part Number: 20162904
Type: Primary high-limit temperature control
Function: Normally-closed, opens on over-temperature
Reset: Automatic (self-resetting on cooldown)
Fits: Goodman & Amana AMVM97 series furnaces
Brand: Goodman (OEM)

OEM vs. Generic

This genuine OEM limit control is factory-calibrated to the precise trip and reset temperatures your furnace requires and matches the original mounting bracket and terminal layout. Generic or universal limits often carry the wrong temperature rating or bracket geometry, leading to nuisance shutdowns or an unprotected heat exchanger. As a primary safety device, it should always be replaced with the correct OEM part.

Installation Difficulty

Moderate (3/5) — Shut off gas and power, remove the blower/control access panel, unscrew the mounting bracket, and transfer the wire terminals to the matching positions. Straightforward for an experienced DIYer; if you are unsure, use a licensed HVAC technician.
