Samsung side by side icing in fridge

[cider]

As per title, our trusty Samsung is playing up. We have had it some 15 years and its moved twice with one 12 month stint in storage. The display started playing up around 7 years ago but its always remained working ok. It has been running ok in our garage the last 7 months however Unfortunately in the last 2 weeks its started freezing items in the fridge side (predominantly in the lower pay) and we have had to throw out a load of veg which didn’t take kindly to the frost effect. We are not wishing to spend anything on it as we would likely buy something smaller instead but is there anything worth checking ? Help much appreciated

Our side by side ( American manufacture ) had the same problem. It had one compressor for the freezer and it chilled the fridge by a fan moving cold air from the freezer into the fridge, when the fridge was cool enough the fan was switched off and a flap moved to close the airway. On ours the flap frosted up and jammed open and even though the fan wasn't running there was enough cold air coming through the airway to over chill the fridge.

The company fitted thermal insulation around the flap and ( if I recall correctly ) also added (or changed) a small heater that was designed to prevent the flap from freezing up. I am not saying that is the problem with yours as some Samsungs do have two compressors and the fridge and freezer are separate systems.
