NORMAL OPERATING SOUNDS
Newer appliances sound different from older appliances. Modern appliances have more features and use newer
technology.
Do you hear what I hear? These sounds 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.
• The cabinet fan runs continuously except when the
door is opened.
CLICKS, POPS,
CRACKS and 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.
• The electronic control board may cause a clicking
sound when relays activate to control appliance
components.
• Expansion and contraction of cooling coils during and
after defrost can cause cracking or popping sounds.

happens when the appliance is first plugged in, when the
door is opened frequently or when a large amount of food
is added to the appliance. The fans help maintain desired
temperatures.

fans come on in order to cool the light bulbs.
• The fans change speeds in order to provide optimal cooling
and energy savings.
