Normal
operating
sounds
Newer appliances sound different from older appliances. Modern appliances have more
features and use newer technology.
Do gou hear what I hear? Thesesounds are normal.
HUMMM...
--WHOOSH...
The new high efficiency compressor
may run faster and longer than your
old appliance and you may hear a
high-pitched hum or pulsating sounds
while it is operating.
Sometimes the appliance runs for an
extended period, especially when the
doors are opened frequently.
You may hear a whooshing sound when
the doors close. This is due to pressure
equalizing within the appliance.
CLICKS, POPS,
CRACKSand CHIRPS
You may hear cracking or popping sounds
when the appliance is first plugged in. This
happens as the appliance cools to the
correct temperature.
Expansion and contraction of cooling coils
during and after defrost can cause
cracking or popping sounds.
The electronic control board may cause a
clicking sound when relays activate to
control appliance components.
WHIR!
You may hear the fans spinning at
high speeds. This happens when the
appliance is first plugged in, when the
door is opened frequently or when large
amounts of beverages are added to
the appliance. The fans help maintain
desired temperatures.
If the door is open for over 3 minutes, you
may hear a fan come on in order to cool
the appliance.
The fans change speeds in order to
provide optimal cooling and energy
savings.
WATER SOUNDS
6
The flow of refrigerant through the
appliance cooling coils may make a
gurgling noise like boiling water.
A water dripping noise may occur as
water from the evaporator flows into
the drain pan.
Closing the door may cause a gurgling
sound due to pressure equalization.
