The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM safety component engineered for the AMVC800804CNAB two-stage variable-speed 80% AFUE gas furnace and compatible AMVC8/GMVC8 platforms. This primary high-limit switch continuously monitors heat-exchanger and plenum temperature, cutting power to the gas valve if the furnace overheats due to restricted airflow, a dirty filter, or a failed blower — protecting the equipment and your home.

Specifications

Part Type: Primary limit temperature control (high-limit switch)
Function: Automatic thermal cut-out on overtemperature
Fits: Goodman/Amana AMVC800804CNAB and related AMVC8 furnaces
Type: OEM replacement — exact-fit terminals and trip point
Reset: Automatic

OEM vs. Generic

This is a genuine Goodman OEM limit control with a factory-calibrated trip temperature. Unlike generic universal limits that require you to match the cut-out rating and bracket, this part drops in with no guesswork. On a safety device, an exact factory trip point matters — a mismatched generic can nuisance-trip or fail to protect the heat exchanger.

Install Difficulty: Moderate

Replacement typically takes 15–25 minutes. Shut off gas and power at the disconnect, remove the two mounting screws, transfer the wire leads, and reinstall. Basic hand tools only. If the limit is tripping repeatedly, diagnose the airflow restriction before replacing — a limit rarely fails on its own.
