OEM Goodman 20162904 Primary Limit Temperature Control

The genuine Goodman/Amana 20162904 primary limit temperature control is the main high-limit safety switch for the AMEC960804CNAC gas furnace. Mounted on the heat exchanger or blower deck, it continuously monitors supply-air temperature and shuts off the gas valve if the furnace overheats — typically due to a dirty filter, failed blower, or restricted ductwork. This automatic-reset control is essential for safe operation and prevents heat exchanger damage.

Specifications

OEM Part Number: 20162904
Type: Primary (high) limit temperature control
Reset: Automatic
Compatible Model: AMEC960804CNAC (and select Goodman/Amana furnaces)
Equipment: Gas Furnace
Function: Overheat cutout for the gas valve circuit

OEM vs. Generic

The OEM control is calibrated to the precise open/close temperatures engineered for your furnace and mounts on the factory bracket without modification. Generic limits may not match the trip setpoint or footprint, causing nuisance shutdowns or unsafe operation. As a life-safety part, OEM is recommended and preserves warranty coverage.

Install Difficulty: Easy

Rated Easy — about 15–20 minutes. Disconnect power, note wire positions, remove the two mounting screws, transfer the wiring to the new control, and remount. Replace your air filter and verify airflow to avoid repeat trips.
