How to Fix / Troubleshooting

Safety: Disconnect power before accessing the control compartment.

Steps:

  • Power reset: Unplug the freezer for at least 10 minutes to allow capacitors to discharge. Plug back in and check if E12 clears.
  • Inspect control board: Access the main control board (often at the rear or top). Look for burn marks, swollen components, or corrosion.
  • Check connectors: Reseat all harness connectors to the board to ensure good contact.
  • Surge protection: If the error followed a storm or power event, consider using a surge protector once repaired.
  • Replace control board: If E12 persists after reset and inspection, replace the main electronic control board with an OEM Westinghouse part.
