Your new high-efficiency refrigerator may

make unfamiliar sounds. These are all normal 

sounds and soon will become familiar to you. 

They also indicate your refrigerator is operating 

as designed. Hard surfaces, such as vinyl or 

wood floors, walls, and kitchen cabinets may

make sounds more noticeable. Listed below 

are descriptions of some of the most common 

sounds you may hear, and what is causing them.

 A.  Evaporator
   The flow of refrigerant through the

evaporator may create a boiling or 

gurgling sound.

 B.  Evaporator Fan
    You may hear air being forced through the 

refrigerator by the evaporator fan.

 C.  Defrost Heater
    During defrost cycles, water dripping onto 

the defrost heater may cause a hissing or 

sizzling sound. After defrosting, a popping 

sound may occur.

 D.  Automatic Ice Maker
   If your refrigerator is equipped with an

automatic ice maker, you will hear ice 

cubes falling into the ice bin.

    These parts can produce a snapping or 

clicking sound when turning the refrigerator 

on and off. The timer also produces sounds 

similar to an electric clock.

 F.  Condenser Fan
    If condenser coils are located underneath 

your refrigerator as shown in the drawing 

at the left, you have a condenser fan. You 

may hear air being forced through the 

condenser by the condenser fan.

 G.  Compressor
   Modern, high-efficiency compressors

operate much faster than older models. 

The compressor may have a high-pitched 

hum or pulsating sound.

 H.  Water Valve
   If your refrigerator is equipped with an

automatic ice maker, you will hear a 

buzzing sound as the water valve opens to 

fill the ice maker during each cycle.

  I.  Drain Pan (Nonremovable)
    You may hear water running into the 

drain pan during the defrost cycle. The 

drain pan will be located on top of the 

compressor for air-cooled condensers 

(black coils on back of refrigerator).

    May create minimal sounds from forced air.



Rigid foam insulation is very energy efficient,

but is not a sound insulator.

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.
