Use and Care Manual

Normal operating sounds.
Newer refrigerators sound different from older refrigerators. Modern refrigerators have more features and
use newer technology.
HUMMM...
WHOOSH...

The new high efficiency compressor may run faster
and longer than your old refrigerator and you may
hear a high-pitched hum or pulsating sound while it is
operating.

Sometimes the refrigerator runs for an extended period,
especially when the doors are opened frequently. This
means that the Frost Guard™ feature is working to
prevent freezer burn and improve food preservation.

You may hear a whooshing sound when the doors close.
This is due to pressure equalizing within the refrigerator.

You may hear
the fans spinning at high speeds. This happens when
the refrigerator is first plugged in, when the doors are
opened frequently or when a large amount of food is
added to the refrigerator or freezer compartments. The
fans are helping to maintain the correct temperatures.


If either door is open for over 3 minutes, you may hear
the fans come on in order to cool the light bulbs.

The fans change speeds in order to provide optimal
cooling and energy savings.
CLICKS, POPS,
CRACKS and CHIRPS

You may hear cracking or popping sounds when the
refrigerator is first plugged in. This happens as the
refrigerator cools to the correct temperature.


Electronic dampers click open and closed to provide
optimal cooling and energy savings.

The compressor may cause a clicking or chirping sound
when attempting to restart (this could take up to 5
minutes).

The electronic control board may cause a clicking
sound when relays activate to control refrigerator
components.

Expansion and contraction of cooling coils during and
after defrost can cause a cracking or popping sound.

On models with an icemaker, after an icemaking cycle,
you may hear the ice cubes dropping into the ice
bucket.
WATER SOUNDS

The flow of
refrigerant through the freezer cooling coils may make
a gurgling noise like boiling water.

Water dropping on the defrost heater can cause a
sizzling, popping or buzzing sound during the defrost
cycle.

A water dripping noise may occur during the defrost
cycle as ice melts from the evaporator and flows into
the drain pan.


Closing the door may cause a gurgling sound due to
pressure equalization.
Do you hear what I hear? These sounds are normal.

icemaker and dispenser operating sounds,
