My samsung fridge/freezer is only 3 years old, just started making loud noise, then when the fridge is opened sounds like the fan making a loud noise that goes down and stops. Then not long after that will start to do that again everything is working fine and everything is being kept cool

if the fan is still running when you open the door , the I would be leaving that idea as a last resort
try this
get 2 taper door chocks and put one either side at the back of the fridge
push the cabinet sideways and slip one chock in a bit then do the other side
many noises are from the bottom plate that the compressor is mounted on from tapping on the floor and lifting it a bit stops the noise
the same as when you open the door the pressure on that plate is removed and so it stops hitting the floor

hello hope this helps , these guys realy help full with
samsung fridge freezer problems

there is a evaporator defrosting problem; ice building-up. the evap fan is mounted right on top of the evap coil. this will get progressively worse; and, the fan will get completely jammed with ice; and stop altogether. your fridge will get warm and the freezer will not cool properly. you should get it looked at asap..

the noise can be from the fan next to the compressor or the fan in the freezer.
check them when you hear the noise if they tuch something or they might need to be replace b/c of berring problems...

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.

There is a design problem with this model. The fridge section is icing over due to a design defect and the noise you can hear is due to the fan on the motor driving against the ice. Eventually the motor will be stopped from running and the fuse will blow in your plug. Contact Samsung and they should replace the defective parts with a fix.

Sounds like the freezer fan is rubbing some wires or possible some foam insulation around the fan. I would look into the freezer compartment fan and go from there. The fan Will Shut off when you open the doors. Let me know how you make out and if you need anymore help.

Thanks,

its a heater cycle problem..the defroster is not working properly. its building up ice in the evaporator that touches the evaporator fan that makes that loud noise but stops when you open a door. it could be either a bad heater, a bad thermo disc or a bad timer.hope i was able to help

12 years old=junk it! Sounds like compressor is going out...Sorry
