Zanussi refrigerator back of fridge builds up ice

I do not believe the problem is the fan. sounds like the frig. is low on Freon this is what will cause the ice build up. you need to find the leak, you can do this by spraying soapy water on coil tubes & watch for bubbles. repair leak & recharge.

Be sure the drain is clear these are well known for drain blockage. the area behind the shelves is where you would find the evaporator and drain hole.

"Always disconnect power before trying to repair any appliance."

There is ice build-up behind the plastic casing. If this is
not removed it will get worse, If you are pretty handy you can remove the white
casing at the back of the fridge and remove the excess ice. If not turn off fridge
and let it defrost completely. The alternative is to call Samsung if still in warrantee,
if not in warrantee they will charge you to compete this and it will not be
cheap!!

Refrigerator or Freezer not Cooling or Getting Cold

more than likely the defroster inside the freezer has gone bad. This defroster is located in the space between the fridge and freezer and activates to defrost the freezer and stop build up of ice in the freezer.. If it is bad the freezer will not keep the fridge nor freezer cold.

Sounds like the unit is goosed and is trying none stop to get the temperature down in the fridge.

That is of course unless the ice is building up like an iceberg inside the cabinet in which case the thermostat has gone

Has this thing a separate frezer and cooler compartment.
Have tried to completely defrost and clean that thing.
At times like in airco's the pinch valve for the cooling process to effect (expansion) is stuck frozen, or very seldom broke.

Yes, I think you have a problem that can be fixed easily by a repair technician. The sound as you described it could have come from the air circulation fan in the freezer compartment striking ice. As the ice builds up it could have stopped the fan from rotating and air flow to the refrigerator compartment.

You have a defrost problem. It means you have 3 parts that can be involve ( timer, defrost thermostat, element) most of the time it's the timer. Hope it was helpful. :)
