  If your Duke Freezer isn't operating, there are several potential causes. First, ensure the freezer is plugged in. Check the fuse or breaker at the main disconnect; make sure the freezer is on a separate circuit. If the beater motor is out on overload, press the overload reset button and check the product temperature. Also, check for a control circuit overload and press the reset button. For other issues like high/low pressure cut-outs, component failure, faulty selector switch, or disconnected/broken wires, it's best to contact your local service company.

  If the dispensed product from your Duke Freezer is too soft, the condenser might be dirty or blocked, restricting airflow. Try to unblock the condenser or have it cleaned by your H.C. Duke & Son, LLC. Distributor. For component failure or leaks in the refrigeration system, contact your local service company.

  If mix is leaking at the dispenser head of your Duke Freezer, it could be due to a faulty head o-ring. Try replacing the o-ring. Also, ensure the head is properly installed, replacing the o-ring if it appears pinched.

  Matthew HendersonAug 27, 2025
  If you notice mix or water leaking from the drain tube drip tray of your Duke Freezer, the beater shaft seal might be damaged or improperly installed. Try replacing the cup seal or o-ring inside the bushing and ensure it's properly installed. If the beater shaft is pitted or damaged where the o-ring rides, replace the beater shaft. For beater shaft end play issues, contact your local service company.
