Switched off 3 days ago to defrost and clean out. Switched on after a day but no lights and no sound of motor. Switched on the Fast Freeze button, appliance then worked, but no other lights came on. Manual says it will automatically switch off after 48 hours but it has not. If Fast Freeze is switched off manually, the motor stops - no lights on. What's wrong? Can anyone help?
