Normal Operating Sounds - Amana Compact Refrigerator Freezer Owner's Manual

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 fan air rushes and whirs.
2. Sealed system (evaporator and heat exchanger)
refrigerant flow gurgles, pops or sounds like boiling
water.
3. Condenser fan air rushes and whirs.
4. Compressor has a high pitched hum or pulsating
sound.
5. Defrost timer sounds like an electric clock and
snaps in and out of defrost cycle.
6. Freezer control clicks when starting or stopping
compressor.
7. Defrost heater sizzles, hisses or pops.
8. Ice cubes from ice maker (some models) drop into
ice bucket.
Water valve (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. (Not
shown)
Foam insulation is very energy efficient and has
excellent insulating capabilities. However, foam
insulation is not as sound absorbent as
previously used fiberglass insulation. (Not shown)
