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.
