Re: Lots of ice in top part of fridge,WHY??
Following on from the previous checks, it could be a number of problems…none of them good i’m afraid 😕
If the ice is fairly uniform across the width of the back and your food is not being frozen in the fridge then the compressor is weak and would need replacing (big expensive job). If the ice is not spread uniformly but restricted to a large section of the back then it may have a gas leak (big expensive job to find the leak and it may not be repairable anyway). If the ice is ‘balling’ in one particular spot then it may be localised insulation failure (big expensive messy job that may not work either)
All in all, you may want to consider replacing the machine…i personally don’t recognise the brand which probably means a cheap badged product 😕
