Goodman 20162903 Primary Limit Switch (150°F)

The 20162903 is a genuine Goodman/Amana primary high-limit switch rated at 150°F for the AMVM970804CNBA modulating, variable-speed 97% AFUE gas furnace. Mounted in the heat-exchanger air stream, this temperature-sensing safety opens the control circuit if supply-air temperature climbs too high — typically from restricted airflow such as a dirty filter, blocked return, or failing blower. It protects the heat exchanger from overheating and cracking.

Part type: Primary high-limit safety switch
Trip temperature: 150°F (factory-calibrated)
Reset: Automatic reset on cool-down
Contacts: Normally closed, opens on over-temperature
Fits: Goodman/Amana AMVM970804CNBA and related AMVM97 furnaces
OEM number: 20162903

OEM vs. Generic

The 150°F setpoint is matched to this furnace's heat-exchanger design. Installing a generic limit with a different trip temperature risks nuisance shutdowns or unsafe operation. The OEM 20162903 guarantees the correct calibration and mounting fit.

Install difficulty

Moderate (2/5). Disconnect the spade terminals and remove two mounting screws, then reverse to install. Cut gas and power first, and note wiring orientation before removal.
