We have a Samsung FR with water and ice dispenser. The display panel has the vacation light on and keeps making an alarm noise. When I try to take the vacation off it just comes back on. The water and ice lock. The fridge is going warm and the inside edge of the fridge door is actually hot. I have rang Samsung and their local engineer want £108 callout charge. As I have no idea of the repair cost just wondering if we should be buying a new appliance. Any help would be greatly appreciated. Thank you.
