Understanding Sounds
You May Hear
Your new refrigerator may make sounds that your old one
didn't make. Because the sounds are new to you, you
might be concerned about them. Most of the new sounds
are normal. Hard surfaces, like the floor, walls, and
cabinets, can make the sounds seem louder than they
actually are. The following describes the kinds of sounds
and what may be making them.
If your product is equipped with an ice maker, you will
hear a buzzing sound when the water valve opens to fill
the ice maker for each cycle.
The defrost timer will click when the automatic defrost
cycle begins and ends. Also, the thermostat refrigera-
tor control, will click when cycling on and off.
Rattling noises may come from the flow of refrigerant,
the water line, or items stored on top of the refrigerator.
Your refrigerator is designed to run more efficiently to
keep your food items at the desired temperature. The
high efficiency compressor may cause your new
refrigerator to run longer than your old one, and you
may hear a pulsating or high-pitched sound.
Water dripping on the defrost heater during a defrost
cycle may cause a sizzling sound.
You may hear the evaporator fan motor circulating the
air through the refrigerator and freezer compartments.
As each cycle ends, you may hear a gurgling sound
due to the refrigerant flowing in your refrigerator.
Contraction and expansion of the inside walls may
cause a popping noise.
You may hear air being forced over the condenser by
the condenser fan.
You may hear water running into the drain pan during
the defrost cycle.
USING YOUR
REFRIGERATOR

Ensuring Proper Air Circulation

In order to ensure proper temperatures, you need to permit
air flow between the refrigerator and freezer sections. As
shown in the illustration, cool air enters through the bottom
of the freezer section and moves up. Most of the air then
flows through the freezer section vents and recirculates
under the freezer floor. The rest of the air enters the
refrigerator section through the top vent.
Do not block any of these vents with food packages. If
the vents are blocked, airflow will be prevented and
temperature and moisture problems may occur.
IMPORTANT: Because air circulates between both
sections, any odors formed in one section will transfer to
the other. You must thoroughly clean both sections to
eliminate odors. To prevent odor transfer and drying out of
food, wrap or cover foods tightly. (See the "Food Storage
Guide" section for details.)
