Sorry for the delay in replying, this will certainly need an engineer out to look at this.
Most likely the fan just needs serving and lubricating, and potentially a new sensor fitted, so the fridge can regulate the temperature and humidity properly, and not have to keep the fan running constantly.
Can you please provide me with your post code and I can then make a recommendation as to an engineer to come out and resolve this issue for you.
Sorry for the delay in getting back to you Bill, your best bet is to use Beko's appointed repair centre.
They can be contacted on 0330(###) ###-####select option 1 followed by option 2 when promoted, they will then provide a further years warranty to your product, have you products serial number to hand when you call (unless you have previously registered it with them).
If your looking to try and get the repair done on the cheap, a local firm could be your best bet, and I would recommend NPC Domestic who are 10 miles from you, their phone number is 01303 892 234
Please let me know if I can be of any further assistance.
