The Goodman 20162903 Primary Limit Switch is a genuine OEM safety high-limit control designed for the AMVC800603BXAA gas furnace and other compatible Goodman/Amana 80% AFUE models. This normally-closed limit switch continuously monitors heat-exchanger temperature and opens the burner circuit if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operating conditions.

Specifications

Trip point: 150°F (open on rise)
Type: Primary / high-limit safety switch
Function: Automatic reset temperature control
Mounting: Furnace vestibule / heat-exchanger panel
OEM Part Number: 20162903
Fits: AMVC800603BXAA and compatible Goodman/Amana furnaces

OEM vs. Generic

Choosing the OEM 20162903 guarantees the exact 150°F trip calibration and mounting footprint your furnace's safety logic depends on. Generic universal limits often carry looser tolerances that can cause nuisance lockouts or, worse, fail to trip at the correct temperature. For a safety-critical component, we recommend the genuine Goodman part.

Install Difficulty

Easy (1/5). Two screws and a pair of spade connectors. Always shut off power and gas at the furnace before servicing. Typical DIY time: 10–15 minutes.
