MY Samsung fridge have a top for freezer. Since 3 week ago the electronic setup is not showing the temperature. The temperature is below what it should be the freezer in not providing cool. the fridge emit a noise when the door is close and the noise stop when the door is open

SOURCE: FREEZER SOUNDS VERY NOISY

Fridge problem could be the fan is bad or that it is hitting ice. When the noise is kind of a buzzing like it is hitting ice...defrost your unit by unplugging and waiting a day or so for full melt out...then check your door gaskets for cleanliness and good seal.

Thanks.

SOURCE: freezer temp too high

Air must circulate in the freezer when working properly. I am guessing the recirculating vent in the freezer may be blocked which would not bring warmer air back to the coil to be cooled. As for the door, I theorize there may be too much negative pressure which pulls the door in while you were pulling out ... don't have solution yet.

The problem is a buildup of ice on the plastic housing (the curved plastic bit) in the back of the freezer under the fixed shelf where the icetub goes. The fan behind this plastic housing is hitting the ice when the defrost comes on.

Unplug the fridge, unpack the freezer, remove the four screws in the back, take off the sheetmetal backing and let the fridge thaw. You can remove the plastic piece after a while and get the ice off (be careful not to remove the styrofoam insulation by going too quickly).

Reassemble and you're back in business, for a few months. I'm never buying Samsung again myself.

Question: was the fridge running when you went to pick it up ?
Was it already on ?
My thinking is that you have the ice build up problem too and that it never thawed. If you unplug it, thawing could take days. Seriously. If you take the inside panel off and get some heat on it
only an hour or so.
You have the exact same model I do, and it works good, just designed poorly. It needs a drain hole on that condensor.
And your fan probably is fine. Do not spend $500.
