and longer than your old refrigerator and you may
hear a high-pitched hum or pulsating sound while it
is operating.
Ŷ Sometimes the refrigerator runs for an extended
period, especially when the doors are opened
frequently. This means that the Frost Guard™

CLICKS, POPS,
CRACKS and CHIRPS
Ŷ You may hear cracking or popping sounds when
the refrigerator is first plugged in. This happens as
the refrigerator cools to the correct temperature.
Ŷ Electronic dampers click open and closed to
provide optimal cooling and energy savings.
Ŷ The compressor may cause a clicking or chirping
sound when attempting to restart (this could take
up to 5 minutes).
Ŷ The electronic control board may cause a clicking
sound when relays activate to control refrigerator
components.
Ŷ Expansion and contraction of cooling coils during
and after defrost can cause a cracking or popping
sound.
Ŷ On models with an icemaker, after an icemaking
cycle, you may hear the ice cubes dropping into
the ice bucket.
WATER SOUNDS
Ŷ The flow of refrigerant through the cooling coils may
