The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control with a 150°F trip point, built for the AMEC960403ANAA gas furnace and compatible Goodman/Amana models. Mounted in the heat-exchanger/plenum airstream, it continuously senses supply-air temperature. If airflow is restricted (dirty filter, blocked ducts, failed blower) and the temperature climbs past its setpoint, the switch opens to de-energize the gas valve and prevent overheating. This is an auto-reset primary limit — it closes again once temperatures normalize.

OEM vs. Generic

The 150°F rating and probe length are matched to this furnace's heat exchanger and cabinet geometry. The OEM Goodman 20162903 trips at exactly the certified temperature. Generic limits with a different setpoint or probe length cause nuisance shutdowns or fail to protect the heat exchanger. Insist on OEM for accurate, safe operation.

Installation Difficulty

Easy (2/5). Disconnect power and gas. Unplug the spade terminals, remove the two mounting screws, and install the new switch in the identical location and orientation so the probe sits correctly in the airstream. Reconnect leads and verify continuity. Typical replacement takes 15–20 minutes.

Protect your furnace from overheating with the genuine Goodman 20162903 150°F primary limit switch.
