If you feel the compressor at the back at the bottom is it hot to touch?
the fridge has been switched off so at the moment its not hot to touch
Ok so the compressor has been running but theres no cooling at all inside the fridge or freezer is this correct?
i just switched it on again now & it sounds as though it turns on & then off again, & yes there is no cooling in the fridge at all
Ok if its coming on and then off and theres no cooling inside the appliance then im afraid you are looking at a system fault here.
Either it short of gas or its a poor pumping compressor. But for either of these you need to get a fridge engineer in as they will need to put there gauges on the pipe wprk at the back to see how much gas is in there and what pressure the compressor is running at.
Sorry but this isn't a diy repair.
Also you will find its quite an expensive fix as a compressor fitted is about the £200 mark and a regas is about £140.
Sorry its not looking like good news but if you need anymore info just get back to me.
