Possible Causes
Corrupted settings in control board memory, Power surge damaging EEPROM, Faulty main control PCB firmware, Loose low-voltage harness to control board
How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains before accessing the control board.
Steps to check and fix:
- 1. Power reset: Unplug the cooler for at least 10 minutes to allow capacitors to discharge. Plug back in and see if E11 clears.
- 2. Restore factory settings: If the user manual provides a key combination to reset to factory defaults, perform that procedure. This can sometimes clear minor memory errors.
- 3. Inspect control board: Access the main PCB and check for signs of surge damage or burnt components. Ensure all low-voltage connectors are secure.
- 4. Replace main PCB: If E11 persists and the unit will not operate, the EEPROM or microcontroller on the board is likely damaged. Replace the main control PCB with a genuine Vestfrost part.
- 5. Surge protection: After replacement, consider using a surge protector to reduce the risk of future memory corruption.
