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.
