We have a fridge freezer, the freezer seems to be fine but the fridge
is not very cold. There is quite a lot of space at the back of the
unit so I don't think that is the problem. I've just defrosted it,
and that didn't seem to help.

Strangly, if I really turn the unit to max cold (only one control
which sets both freezer and fridge), ice seems to build up at the
back of the fridge, but the whole fridge doesn't seem to get very
cold.

This seems really odd to me, how can the back freeze but stuff in the
door stay luke warm.

If there usually come kind of fan (which might have broken) to blow
air around the fridge from the freezer ?

Would appreciate any help or advice. Its a decent Bosch unit, but is
getting a little old now, maybe its time to get a new one.

1. Ice is a very good insulator. Lots of ice prevents cooling.
2. Abnormal amounts of ice indicate an air leak somewhere (humid air gets
in, freezes).
