Anyone any experience.

Had my fridge around 2 years, it was a cheap one from Currys for 2 ton.

The freezer works grand, but the top fridge no longer gets cold. The fridge is barely cool, but certainly not room temperature. The temp dial does nothing, and the compressor doesn't seem to kick in now as you can't hear it.

I do have moisture built up on the back wall on the inside of the fridge, and there is a condensation drain plug at the back that is filled with water, and casing small ice to form around it in the fridge,

Any idea what's going on?

Should this drain be empty? Tried turning on and off for a while and can't seem to get the compressor to kick in, so presume it's knackered?
