The Goodman 20162903 Primary Limit Switch is a genuine OEM auto-reset high-limit control rated at 150°F. Mounted on the heat-exchanger or blower deck, it monitors supply-air temperature and cuts the burners if the furnace runs too hot — typically from restricted airflow such as a dirty filter or failed blower. Once temperature returns to normal, it resets automatically. This is a factory-correct replacement for the Amana/Goodman AMEC960603ANAA gas furnace.

Specifications

Type: Primary high-limit switch (auto reset)
Trip point: 150°F
Function: Opens burner circuit on high supply-air temperature

OEM vs. Generic

The 150°F set point and bracket geometry are matched to your furnace's cabinet. Genuine OEM guarantees the correct trip temperature, so you avoid nuisance short-cycling from a mismatched generic switch — and keep the intended overheat protection intact.

Installation Difficulty

Easy (2/5). Cut power and gas, remove two mounting screws, transfer the two spade terminals, and reinstall. If the switch was tripping, clear the airflow restriction first.
