Operating Sounds
Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were not
present in an older model. These improvements were made to create a refrigerator that is better at preserving food,
is more energy efficient, and is quieter overall. Because new units run quieter, sounds may be detected that were
present in older units, but were masked by higher sound levels. Many of these sounds are normal. Please note that
the surfaces adjacent to a refrigerator, such as hard walls, floors and cabinetry may make these sounds seem even
louder. The following are some of the normal sounds that may be noticed in a new refrigerator.
