Ok the fan inside the fridge section just circulates the air around it doesn't really control the temperature inside and it wont affect the freezer section.
The compressor at the back is it to hot were you cannot keep you hand on it?
yes, it's too hot to keep your hand on it.
Ok a compressor shouldn't be that hot. It only goes like that if its working overtime.
As its not getting cold proberly inside the appliance and the compressor is hot to touch then im afraid it has a system fault.
Either its a poor pumping compressor (more common) or its short of gas. But for either of these you need to get a fridge engineer in.
As they will need to put there gauges on the pipe work at the back to see whats happeing inside the system.
Im sorry but this isn't a diy fix and it isn't going to be cheap. As if its a compressor fault then you are looking at about the £200 mark. If its short of gas then its about £140.
Sorry its not good news but if you need anymore info just get back to me.
I think the compressor has always been hot. I think we're better off buying a new appliance rather than attempting a repair. It cost around £275 to buy, so is not that expensive.
Any recommendations on the best make for a fridge freezer combo, or should I buy a separate fridge and freezer?
A compressor is normally warm but should never be hot were you cannot keep your hand on it.
You are right its proberly best to replace rather then fixing this as its never really the same when you break into the system.
As to a best make you can try either a Bosch or AEG as they are decent appliances.
The separate appliances are good in a way if one breaks down you still have the other but if theres no room or limted plug sources then it will have to be a fridge freezer.
But you can try a frost free appliance as these are quite good now a days and it saves you defrosting every 6 months.
OK. So the freezer has now been defrosted and it's working again. The noise has gone and the compressor has cooled down.
So it looks like it just needed to be defrosted after all
