Do you hear what I hear? These sounds are normal.
• 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.
• 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.
