I need more information Ruth. Tell me roughly how tall the appliance is, and what proportion of it fridge and what is freezer. If possible to pull it away from the wall, look at the base and identify whether one or two compressors (large black cylindrical shape thing). If the unit is plugged in, unplug it and place your hand on the compressor(s) to feel if they are hot - be careful. If the unit was unplugged anyway, plug it in now, and listen for the motor(s) working, again you can check (carefully) with your hand to feel for vibration from within the unit. Tell me your findings. Finally roughly how old is it. You will of course have checked the fuse ?
