TROUBLESHOOTING GUIDE

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.
• The defrost timer will click when the automatic defrost cycle
begins and ends. The thermostat control (or refrigerator
control, depending on the model) will also 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.
• 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.
• Water dripping on the defrost heater during a defrost cycle
may cause a sizzling sound.
• 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.
