NORMAL OPERATING SOUNDS

There are multiple high-speed fans inside
your refrigerator which help it to maintain the
temperature you have selected. Whirring is
common when the refrigerator is first plugged in,
when the doors have been opened often or for an
extended period of time and when a large amount
of food has been added.
This is a common noise that comes from
the compressor and is a part of making your
refrigerator run efficiently.
It is possible that you may hear a whooshing
noise when closing the doors. This is no cause
for concern. It is simply the pressure in the
refrigerator equalizing.

• There are a lot of things going on in your
refrigerator at any given time. Additional noises
you may hear, and possible causes include:
• Gurgling is most likely due to the circulation of
refrigerant through the cooling coils.
• Sizzling or popping sounds can be frost melting
and falling onto the defrost heater during the
defrost cycle.
• Clicking or chirping may be heard as the
compressor attempts to re-start.
• Cracking or popping noises may be from the
expansion and contraction of cooling coils during
and after the defrost cycle.
• Also, when your refrigerator is first plugged
in, the foam insulation in the walls will cool and
contract, which can result in cracking or popping
noises.
• The defrost timer and thermostat control will
click as each cycles on and off.
If the refrigerator has been placed in a horizontal
position for any period of time, wait 4 hours after
returning it to the upright position before plugging
it in.
