This is a very common fault on these appliances. As this machine is actually made by Beko and ive come across this fault a lot on these.
Its usually the small temperature board inside the fridge. If you look at the dial inside the fridge behind there is a small circuit board which regulates the temperature inside the appliance.
This is usually the part that failes in there and causes this fault.
But sometimes it can turn out to be the rear control on the back instead.
Now what I do when I get this fault is replace both parts as to be honest they are not that expensive on these
As the rear board is £21 and the other is about £15 so parts are not that expensive on these.
So if you wanted to just try one then go for the small board inside the fridge and see what happens.
But for this its gong to be either the small board inside or the rear board.
If you need anymore info just get back to me.
Thanks for the info. I would not expect any of the components to fail in 4 years - the life of a fridge freezer must be 5+ years and so I am hoping I can persuade the retailer/manufacturer to put the fault right. I shall mention my statutory consumer rights and hope that they will concur.
Where would I buy the circuit boards you mention? Thanks for your help.
Sorry for the delay.
For spares you can try these www.buyspares.co.uk and they should have the parts you need.
Bit slow at getting back to you - there doesn't seem to be a circuit board inside the fridge itself - there's the dial control and behind it the sealed unit containing the light - no obvious bits to unscrew - but there is a plastic rectangle on the back of the fridge about 7" x 4" and I am imagining this would contain what you refer to as "the rear control" - could it be that my combi only has the one circuit board? Thanks for your help.
Many thanks for all of this. I am hoping I can now persuade my local appliance fixer that this is what the problem is and he will be able to go ahead with the replacement boards. You have been extremely helpful. Very many thanks. SAR
Your very welcome.
