Fridge freezing vegies??!!

[Daffodil Mumma]

In the last few weeks my fridge has been playing up All my fruit n vegies are freezing...originally I had them in the crisper so when they started freezing I swapped them with hubby's beer...but no matter where they are in the fridge they still freeze, especially the lettuce and cucumber And Ive noticed any dairy products dont seem to be keeping cold enough.
The fridge is a fisher & paykel frost free upside down one. Its pretty old (like maybe 10 years give or take) Until I can find work I really cant afford to buy a new one and the repair guy I called wouldnt offer any advice and said I would be looking at a $110 call out fee + labour and parts! Ouch!
So anyway Im just wondering if anyone has any ideas or advice on how I can fix this without costing a fortune???

Maybe the fan isnt working properly. Is something blocking it? What about the seals, do they need replacing? Look in your local paper if you need someone to come, I can quite often find someone cheaper by ringing around the ads in there.
Not much help, but anyway, good luck
