Years ago if you looked at the back of a fridge you'd see the condenser coils. When I was looking for a new fridge recently I noticed that most models have the back covered with a sheet of what looks like corrugated plastic. I assumed that this was for protection and would be removed on installation.
Not so - my new replacement does not mention removing the back and wouldn't be straightforward. I thought that condensers should be in open air for efficiency. What's going on?
NB the entire back is covered apart from a 20 cm gap at the bottom where one can see the compressor etc.
