The genuine OEM Goodman 20162904 Primary Limit Temperature Control is a direct-fit replacement for AMVC80805DNCA variable-speed gas furnaces. Mounted on the heat-exchanger bulkhead, this auto-reset high-limit control continuously monitors supply-air temperature. If airflow is restricted or the furnace overheats, it interrupts the burner circuit to prevent heat-exchanger damage, then automatically resets once temperatures return to a safe range.

Specifications

Part Number: 20162904
Type: Primary Limit / High-Limit Temperature Control
Contacts: Normally closed (opens on over-temperature)
Reset: Automatic
Compatibility: Goodman & Amana AMVC80805DNCA 80% AFUE furnaces

OEM vs. Generic

This control is factory-calibrated to the precise open/close temperature setpoints Goodman/Amana specify for your furnace. As a safety-critical component, it should never be replaced with an unrated universal part — the wrong trip point can permit unsafe operation or cause repeated nuisance lockouts. The OEM 20162904 guarantees the correct calibration, terminal layout, and mounting footprint.

Installation Difficulty

Moderate (2.5/5). Disconnect the wiring, remove the mounting screws, and install the replacement in the identical position and orientation so the sensing element sits correctly in the airstream. Always shut off gas and power first. If the limit has been tripping, have a technician diagnose airflow issues (dirty filter, blocked coil, failing blower) before returning the furnace to service.

Genuine OEM primary limit control for Goodman and Amana AMVC80805DNCA furnaces.
