Strange replied to this, this morning bl**dy internet!!

Anyway, the model is a ZFC62/23. I failed to mention that i'd moved it
and it had been lay down on its side for quite a few hours (yes i know
now i shouldn't have!).

A guy from the local electrical shop said turn it upside down for 24
hours then turn in back for 24 hours then if that doesn't work bin it!

Also someone said to me that sometimes if the gas is low, it will only
be able to cooler the freezer compartment and not the fridge ?? - does
that sound likely?

Cheers in advance.
