Please can anyone tell me what is likely to be wrong with my fridge? The backwall, approx halfway up is quite warm to touch. The top and bottom is fairly cold with a thin layer of ice. The drain does not seem to be blocked (water freely running through the drain). There does not seem to be any cool air circulating within the fridge.
The freezer is not affected.
Is there anything I could do myself before calling out an engineer?
Many thanks Lloydy 27
