Hi all, hope someone can help.

My 'frost free' fridge freezer has a lot of built up ice on the area above the top shelf.

I have had a look round forums, and found out a lot about ice forming at the bottom of the freezer but not at the top.

I should also mention that the fridge is quite cold too and the thermostat is set very low.

Is this simply a case of a faulty thermostat? Should I defrost it manually and see if that remedies it?

The fridge freezer is only a couple of years old.

Many thanks for any advice!
