Maintenance and Service

Problem
a break in the opera-
tion of the freezer
the freezer compressor
operates
continuously
The sounds that can be heard during normal operation:
• clicks - heard when the control activates or deactivates the compressor
• buzz - the sound of the compressor intensely working shortly after its activation
• crackles and clatter - coming from the cooling system, caused by expansion and shrin-
king of parts due to temperature differences before and after compressor activation
• rustle, gurgle, whistle - coming from the cooling system piping, caused by the co-
olant flowing inside.
● Expanding and shrinking of parts caused by temperature changes causes crackling
sounds that may be heard
Easily corrigible sources of noise:
● noise caused by the appliance positioned not level - adjust the position with the
adjustable turn-in front feet.
● rubbing the adjacent piece of furniture - move the refrigerator a bit.
● creaking of the drawers and shelves - take out and put back the drawer or shelf.
