The display won't turn on — what happened?

As we always recommend, start by checking the socket with another appliance (for example, a hairdryer or a lamp) to confirm there is power.

After that, there is not much else you can do at home, because the most likely cause is a damaged electronic control board. On older fridges, it could also be a thermostat or compressor issue. These are checks that only a qualified engineer can carry out.
