Normal Operating Sounds - GE 22, 25 Owner's Manual

Normal operating sounds.

These sounds are normal and
are due mostly to highly efficient
operation.

Icemaker (on some models). Occasionally you will hear ice cubes dropping
into the ice bin. If this is your first icemaker, you'll hear occasional sounds
that may be unfamiliar. They are normal icemaking sounds and are not
a cause for concern.
The icemaker water valve will buzz when the icemaker fills with water. If the
power switch is in the I (on) position it will buzz even if it has not yet been
hooked up to water. Keeping the power switch in the I (on) position before it is
hooked up to water can damage the icemaker. To prevent this, set the power
switch to the O (0ff) position. This will stop the buzzing.
Evaporator Fan.* You may hear air being forced through the cabinet by the fan.
The fan operates at different speeds depending on cooling needs. If either door
remains open for more than 3 minutes, the fan will come on.
Evaporator. The flow of refrigerant through the evaporator may create a slight
bubbling or gurgling sound.
Defrost Heater. During defrost cycles, water dripping onto the heater may cause
a hissing or sizzling sound. After defrosting, a popping sound may occur and the
evaporator may create a slight bubbling or gurgling sound.
Plastic Liner. Cracking or popping sounds due to expansion of the plastic liner.
This occurs mainly when cooling down from room temperature.
Water Valve (on models equipped with an automatic icemaker). When the icemaker
fills with water, a buzzing sound and running water will be heard. If you have low
water pressure, you may hear the icemaker cycle several times when making one
batch of ice.
Water Pan. Water may be heard running into the maintenance-free drain pan
during the defrost cycle.
Compressor.* Modern, high efficiency compressors operate much faster than
older models. The compressor may have a high pitched hum or pulsating sound.
Condenser Fan.* You may hear air being forced over the condenser by the fan.
* When the control settings are changed, the compressor and fans may not react immediately.
