Larder fridge - possible condensor problem?

[Fishingsmurf]

I've got a 4 year old Electrolux 7620 larder fridge which over the last week has been getting more frost on the back of the fridge than usual. The condensor seems to be running a lot more than normal as well. This is a free-standing unit in a utility room, loads of space around it, and I've have brushed the rear of the fridge and the condensor itself, but it doesn't seem to have had any effect.

Is there anything else I can have a try with before I assign the fridge to the dump?

Thanks,
Paul

the fridge is working overtime, and the contents are starting to freeze up.

It is obvious, but you neglect to tell us, have you checked the setting you normally have set ? has someone changed it ?

Setting hasn't been changed.
