Normal Operating Sounds
This new refrigerator may be replacing a differently
designed, less efficient or smaller refrigerator. Today’s
refrigerators have new features and are more energy
efficient. As a result, certain sounds may be unfamiliar.
These sounds are normal and will soon become familiar.
These sounds also indicate refrigerator is operating and
performing as designed.
1. Freezer control clicks when starting or stopping
compressor.
2. Freezer fan air rushes and whirs.
3. Sealed system (evaporator and heat exchanger)
refrigerant flow gurgles, pops or sounds like boiling
water.
4. Defrost heater sizzles, hisses or pops.
5. Defrost timer sounds like an electric clock and
snaps in and out of defrost cycle.
6. Condenser fan air rushes and whirs.
7. Compressor has a high pitched hum or pulsating
sound.
8. Ice cubes from ice maker (some models) drop into
ice bucket.
9. Ice auger (Ice and Water
Dispenser models) hums
as auger agitates ice during dispensing.
10. Ice maker water valve hookup (some models)
buzzes when ice maker fills with water. This occurs
whether or not refrigerator is connected to water
supply. If refrigerator is not connected to water
supply, stop sound by raising ice maker arm to off
position.
11. Foam insulation is very energy efficient and has
excellent insulating capabilities. However, foam
insulation is not as sound absorbent as
previously used fiberglass insulation.
