Normal Operating Sounds & Sights
UNDERSTANDING THE SOUNDS YOU MAY HEAR
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.
NOTE: Rigid foam insulation is very energy efficient,
but is not a sound insulator.
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.
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.
