Normal Refrigerator Operating Sounds
Your refrigerator/ice-maker combo features rigid foam
insulated cabinets to provide high thermal efficiency
and maximum sound reduction for its internal working
components. In spite of this, the unit still may make some
unfamiliar sounds.

because of the unit's environment. Hard surfaces such as
fi berglass fl oors have a tendency to refl ect normal appliance
operating noises.
