Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F for the ACV90704CXBA gas furnace. Mounted on the heat exchanger or supply plenum, this switch continuously monitors discharge air temperature and opens the circuit to shut down the burner if the furnace overheats — typically due to restricted airflow from a dirty filter, blocked ducting, or a failing blower. It automatically resets once temperatures return to a safe range, protecting the heat exchanger from thermal damage.

OEM vs. Generic

The temperature setpoint and mounting bracket on a limit switch must match the furnace exactly. Generic 150°F switches may differ in trip tolerance or bracket geometry, risking nuisance trips or improper protection. This genuine OEM Goodman switch delivers the correct 150°F calibration and bolt-in fit for the ACV90704CXBA.

Installation Difficulty

Easy–Moderate. A two-wire, two-screw replacement most DIYers can complete in about 20–30 minutes. Disconnect power before servicing, and address any airflow restriction that may have caused the trip.
