The Goodman 20162906 M4 Primary Limit Switch is a genuine OEM high-limit safety control for the ACVC961005CNBA furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or burner partition, it monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger and your home from a runaway high-temperature condition.

  • OEM Part Number: 20162906
  • Type: Primary (high) limit switch, M4 series
  • Function: Automatic-reset thermal overheat cutoff
  • Equipment: Furnace (gas)
  • Compatibility: Goodman ACVC961005CNBA and ACVC9 series

OEM vs. Generic: The limit's trip temperature and mounting geometry are matched to this specific furnace. A generic switch with the wrong setpoint can nuisance-trip (short cycling) or, worse, fail to open at the correct temperature — a safety risk. Genuine Goodman limits carry the factory calibration, ensuring the furnace shuts down exactly when it should.

Install Difficulty: Moderate (2/5) — disconnect power, remove two mounting screws, transfer the wire connectors, and reinstall. A multimeter continuity check is recommended. When in doubt, use a licensed HVAC technician.
