[C320-list] Fridge not chilling as effectively…where to start?

[David Hayes]

Hi all,
Our fridge has always (ok, we've only owned the boat for 3 years but...) worked very effectively and we have always found that we have ice cubes after just a few hours.  But on our last couple of trips it was not quite as effective, and on a short trip this weekend it did not manage to freeze the ice cube tray at all even though we had it on full all day/night.  It is cooling, but just not as well as it normally does.  The weather is quite mild here at the moment so no environmental factors of note.
I believe it's the original fridge which I think is the Adler Barbour...2006 model boat.  Compressor etc is located in stern port locker on the shelf.
For some reason it's about the only appliance on the boat for which I do not seem to have a manual.

Any thoughts appreciated regards where I should start to investigate given the symptoms.
