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, such as the floor, walls, and cabinets, can make the 
sounds seem louder. The following describes the kinds of sounds 
and what may be making them.

■

If your refrigerator 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.

■

Your refrigerator is designed to run more efficiently to keep 
your food items at the desired temperatures and to minimize 
energy usage. The high efficiency compressor and fans may 
cause your refrigerator to run longer than your old one. You 
may also hear a pulsating or high-pitched sound from the 
compressor or fans adjusting to optimize performance.

■

You may hear the evaporator fan motor circulating air through 
the refrigerator and freezer compartments. The fan speed 
may increase as you open the doors or add warm food.

■

Rattling noises may come from the flow of refrigerant, the 
water line, or items stored on top of the refrigerator.

■

Water dripping on the defrost heater during a defrost cycle 
may cause a sizzling sound.

■

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.
