The genuine Goodman 20162903 Primary Limit Switch is the 150°F auto-reset high-limit safety control for ACSS961005CNAA gas furnaces. Mounted on the heat-exchanger plenum, it monitors supply-air temperature and shuts off the gas valve if the furnace overheats — typically caused by restricted airflow from a dirty filter, blocked ductwork, or a failed blower — then automatically resets once temperatures return to normal.

OEM vs. Generic

This factory OEM Goodman limit is set to the exact 150°F trip point your furnace was engineered around. Generic switches with the wrong temperature rating cause short cycling or allow dangerous overheating. For a primary safety control, match the OEM part exactly.

Installation Difficulty

Moderate (3 of 5). Disconnect power, unplug the two terminal wires, remove the mounting screws, seat the new limit, and reconnect. Standard hand tools and basic electrical knowledge required.

If the limit keeps tripping, correct the airflow restriction before assuming the switch has failed.
