The Goodman 20162903 Primary Limit Switch is a genuine OEM high-temperature safety control engineered for the AMH950704CXAA gas furnace and compatible Goodman/Amana models. This limit switch continuously monitors heat-exchanger temperature and opens the burner circuit if the furnace exceeds its safe operating threshold, protecting the heat exchanger, blower, and surrounding components from overheating.

Specifications

Trip temperature: 150°F (auto-reset)
Type: Primary high-limit safety switch
OEM part number: 20162903
Fits: Goodman/Amana AMH950704CXAA and select 95% AFUE furnaces
Terminals: Standard 1/4" quick-connect spade

OEM vs. Generic

This is a factory-original Goodman component built to exact temperature and dielectric tolerances. Generic aftermarket limit switches may trip early or late, causing nuisance shutdowns or, worse, failing to cut power during a genuine overheat event. Because this is a life-safety device, we recommend the OEM part to guarantee your furnace's factory-rated protection and preserve equipment warranties.

Installation Difficulty

Easy — a two-wire swap that most homeowners with basic tools can complete in 10–15 minutes. Always cut power to the furnace at the breaker before servicing. If the switch trips repeatedly after replacement, have a technician inspect airflow and the heat exchanger, as chronic tripping usually indicates an underlying restriction rather than a bad switch.

All parts are genuine Goodman OEM and backed by our fast-shipping guarantee.
