The genuine OEM Goodman 20162903 Primary Limit Switch is the main high-limit heat sensor for the Goodman VMS80805CNAA gas furnace. Mounted on the heat exchanger/blower deck, it opens at approximately 150°F to shut off the burners if supply-air temperature climbs too high — typically from restricted airflow, a dirty filter, or a failed blower. It automatically resets once the furnace cools to a safe temperature.

Specifications

Type: Primary high-limit switch
Trip temperature: ~150°F (auto reset)
Function: Over-temperature burner cutoff
Fits: Goodman VMS80805CNAA and compatible 80% AFUE furnaces
OEM Part Number: 20162903

OEM vs. Generic

The 150°F calibration and disc geometry are matched to this furnace. OEM 20162903 ensures the correct trip point and mounting bracket; a generic limit with a different set point can cause nuisance shutdowns or, worse, fail to protect the heat exchanger.

Install Difficulty

Easy (2/5). Two screws and two wire terminals. Cut power before servicing. If the limit is tripping, correct the airflow restriction rather than simply replacing the part.
