The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F, designed as an exact-fit replacement for the AMEC961005CNAC gas furnace and compatible Amana and Goodman models. Mounted on the heat exchanger or burner box, this control monitors supply-air temperature and shuts off the burners if the furnace overheats — typically due to restricted airflow, a dirty filter, or blower failure — protecting the heat exchanger from cracking.
The OEM 20162903 is factory-calibrated to the precise 150°F trip point and mounting footprint required for this furnace. Generic switches with a different set point or bracket can cause nuisance shutdowns or fail to protect the heat exchanger. For safety-critical limits, OEM is the recommended choice.
Easy–Moderate. With power off, disconnect the wire terminals, remove the two mounting screws, and install the replacement in the same orientation. If the limit keeps tripping, check the filter, blower, and ductwork for airflow restriction before assuming the switch has failed.
