Hi im hoping someone may have some idea what might be wrong with our fridge freezer and if its worth trying to get it repaired. It seems to be constantly running with the usual fridge noise but over the past week it keeps thawing in the freezer and the fridge isnt really getting cold at all. We've defrosted it fully and when we leave it switched off for a while then turn it back on it freezes for a couple of hours but then thaws again. Have hoovered the grill on the back, the motor/compressor is warm. Theres a copper coloured pipe inside the freezer at the back and that seems to freeze over very fast but the metal shelves in the freezer take a while to freeze and then thaw again. Its around 5yrs old but still looks new and seems a shame to get rid without trying to fix it, especially as it still seems to be trying to work and hasnt just died altogether.
