Normal Operating Sounds - GE MTS18GS Owner's Manual And Installation Instructions

Normal operating sounds.

Newer refrigerators sound different from older refrigerators. Modern refrigerators
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
n
longer than your old refrigerator and you may hear a
high-pitched hum or pulsating sound while
it is operating .
You may hear a whooshing sound when the doors close .
n
This is due to pressure equalizing within the refrigerator .
CLICKS, POPS,
CRACKS and CHIRPS
You may hear cracking or popping sounds when
n
the refrigerator is first plugged in . This happens as
the refrigerator cools to the correct temperature .
The compressor may cause a clicking or chirping
n
sound when attempting to restart (this could take
up to 5 minutes) .
Expansion and contraction of cooling coils during and
n
after defrost can cause a cracking or popping sound .
On models with an ice maker, after an ice making
n
cycle, you may hear the ice cubes dropping into the ice
bucket .

You may hear the fans spinning at high speeds .
n
This happens when the refrigerator is first plugged in,
when the doors are opened frequently or when a large
amount of food is added to the refrigerator or freezer
compartments . The fans are helping to maintain the
correct temperatures .
WATER SOUNDS
The flow of refrigerant through the freezer cooling coils
n
may make a gurgling noise like boiling water .
Water dropping on the defrost heater can cause a
n
sizzling, popping or buzzing sound during the defrost
cycle .
A water dripping noise may occur during the defrost
n
cycle as ice melts from the evaporator and flows into
the drain pan .
Closing the door may cause a gurgling sound due
n
to pressure equalization .
