Sorry to hijack this post but couldn't work out how to start a new thread.
I have read loads of good stuff on here and thanks guys it was really helpful.
My problem is the fridge stopped getting cold - Hotpoint Iced diamond frost free. I took the advice on here and defrosted it but only waited 12hrs but it kicked off and hey presto got cold again. However it only lasted 2 days and started getting warm again. I decided to do as told on here and turned it off for 48hrs switched it back on and great it was working again. Problem is again after 2 days it has started to cool down again and looks like it is going again.
Any more ideas is the thermostat on its way out, is it worth getting an engineer out or is it ready for the skip.
