Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control for the Amana/Goodman AMH80803BXBD gas furnace. This bimetal safety switch monitors heat-exchanger and plenum temperature and opens the circuit to the gas valve if the furnace overheats — protecting the heat exchanger from cracking due to restricted airflow, a dirty filter, or blower failure. A failed or drifted limit control is a common cause of short-cycling and no-heat lockouts.

Specifications

Type: Primary high-limit (auto-reset bimetal)
OEM Part Number: 20162904
Function: Overtemperature safety shutoff
Compatible model: AMH80803BXBD
Mounting: Furnace-specific bracket/opening temperature

OEM vs. Generic

Universal limit switches require you to match trip temperature and mounting depth by hand — get it wrong and the furnace either nuisance-trips or fails to protect the heat exchanger. This OEM control arrives pre-calibrated to the exact open/close temperatures Goodman specifies for this cabinet, so it drops in and works correctly the first time.

Install Difficulty

Easy to Moderate — cut power, remove two mounting screws, transfer the wire leads, and secure the new switch. No calibration required. A basic multimeter helps confirm continuity before and after.
