The Goodman 20162906 M4 Primary Limit Switch is a genuine OEM high-limit safety control for the ACVC960403BNAA gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger / blower deck, this primary limit continuously monitors supply-air temperature and opens the circuit to cut burner operation if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. Once temperatures normalize it automatically resets, restoring normal heating.

OEM vs. Generic

The primary limit is a critical safety device factory-calibrated to a specific trip temperature. This genuine OEM Goodman switch matches that setpoint exactly. A generic switch with the wrong rating can cause short-cycling or fail to protect the heat exchanger. Choose OEM for safe, reliable operation.

Install Difficulty

Moderate (2/5) — Disconnect the two leads, remove the mounting screws, and swap in the new switch. Power and gas off before servicing; address any airflow restriction that caused the trip. When in doubt, hire a licensed technician.
