I think it's a single compressor, it's a ZFC62/23 FF. Got a large
single condensor on the back, and compressor on the bottom.

The fridge was working fine but it's been off for a few months and
then i transported it on its side (yes i know!) in a van where it was
left overnight.

From what i've read it sounds like it either needs recharging as
there's not enough gas to cool the freezer and the fridge together, or
that because i've had it on its side then maybe oil has got into the
discharge pipe and cusing a blockage ??

Thanks
