The Goodman 20162903 is a genuine OEM primary limit switch rated at 150°F, designed for the AMVC80604BNAA gas furnace. Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and opens the control circuit if the blower fails or airflow is restricted, protecting the heat exchanger from cracking due to overheating. A furnace that short-cycles on high limit or shuts down after a few minutes of heat often needs this switch.

Specifications

Type: Primary auto-reset high-limit switch
Trip temperature: 150°F (auto-reset on cooldown)
Terminals: 1/4" quick-connect spades
Mount: Bulkhead flange, 2-screw
Fits: Goodman/Amana AMVC80604BNAA and compatible models
OEM Part No: 20162903

OEM vs. Generic

The 150°F trip point is model-specific; installing a generic limit with a different rating can allow dangerous heat-exchanger temperatures or cause constant nuisance trips. OEM guarantees the correct set point and flange fit.

Installation

Difficulty: Easy (2/5). Cut power, photograph wiring, remove two screws, swap the spade connectors, and reseat against the heat-exchanger panel. Confirm normal cycling. Typical time: 10–15 minutes.
