Rsa1ntpe making loud noises and noticed cracks in the plastic in the freezer,?

The ice has now accumulated around the condenser fan and also around the compresser too and needs to be removed.

At the back of the freezer you should find a set of screws holding the plastic panel in place. The fan will be behind that.

What you need to do is either tightn the screws on the fan motor or add some washers to the cover to tighten it up. There could be a small crack in the plastic that could be vibrating too. If the noise drives you nuts you can order a replacement cover from the manufacturer. Good luck

Change the compressor relay.

Some refrigerators have a small plastic fan under the bottom shelf of the freezer that circulates air. It's not too unusual for a heavily loaded shelf to rub the fan blades making the noise you describe. If you empty the freezer, you'll fin a few screws holding the bottom shelf in. remove the shelf and inspect the fan and surrounding parts for signs of rubbing. Also tug on the fan blade lightly to see if it is still attached to the motor's shaft securely. New fan blades can be purchased at a good appliance repair shop. Good Luck

8yr old? Buy a new one. The cracking sound is from expansion and contraction of the cabinet and ice cooling or defrosting. It can be as simple as a bit of a top up of refrigerant, but can also be that your compressor has worn down the valve plates and therefore is not producing sufficient pressure throught the system.

Replace the fan motor. Sounds like bearings are going bad.

Its the plastic cassing making the noise. If you press the tv together along the edges you will here a crack. Samsung and others did not use 99 cent padding between the plastic and the metal you need cushion padding. Its like not using a gasket or seal. Its a simple fix but the tv companies say its expansion.

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.

If the noise from the compressor sounds like a humming followed by a click, the compressor is "short cycling". Could be either the compressor relay or the compressor itself is bad. Not sure on the hissing noise. Could be just a loose panel that needs to be tightened or adjusted.
