Fridge cooling problem

[Rollerball]

I have a Baumatic BR16.3A - it was purchased 2 years ago (and 2 weeks!).

A couple of weeks ago the thermometer I put inside indicated that it wasn't quite as cool as expected (6 degrees instead of the usual 4). I adjusted the thermostat and all was well.

However, the same thing has happened again and I've adjusted the thermostat once more. Unfortunately I'm nearing the limit of the thermostat!

There is, at times, some ice on the rear panel - nothing unusual there as it comes and goes.

Any thoughts please?

Unfortunately it's JUST out of the labour warranty (parts are still covered though).

Note: the thermostat goes from 0 to 5 (with 5 being the coldest) - the recommended setting is between 3 and 4. I haven't filled up the fridge with too much food, so no circulation problems, etc.

Thanks

Fridge stats do fail, it may be on it's way out.
