Normal Operating Sounds and sights

Understanding the Sounds you may Hear

Your new, high-efficiency refrigerator may introduce unfamiliar sounds. These sounds normally indicate your refrigerator is operating correctly. Some surfaces on floors, walls, and kitchen cabinets may make these sounds more noticeable.

NOTE

Rigid foam insulation is very energy efficient, but is not a sound insulator.

Following is a list of major components in your refrigerator and the sounds they can cause:

AEvaporator Refrigerant through the evaporator may create a boiling or gurgling sound.

BEvaporator fan You may hear air being forced through the refrigerator by the evaporator fan.

CDefrost heater During defrost cycles, water dripping onto the defrost heater may cause a hissing or sizzling sound. After defrosting, a popping sound may occur.

IMPORTANT

During the automatic defrost cycle, you may notice a red glow in the vents on the back wall of your freezer compartment. This is normal during the defrost cycle.

DAutomatic ice maker When ice has been produced, you will hear ice cubes falling into the ice bin. The icemaker will produce 2.5 to 3 pounds of ice every 24 hours depending on usage conditions.

EElectronic control & automatic defrost control These parts can produce a snapping or clicking sound when turning the cooling system on and off.

FCondenser fan You may hear air being forced through the condenser.

GCompressor Modern, high-efficiency compressors run much faster than in the past. The compressor may have a high-pitched hum or pulsating sound.

HWater valve Makes a buzzing sound each time it opens to fill the ice maker.

IDrain pan (not removable) You may hear water dripping into the drain pan during the defrost cycle.

JCondenser May create minimal sounds from forced air.
