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 to you. They 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 and cycles on and off. 8. Ice cubes from ice maker (some models) drop into ice bucket. 9. 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. Ice maker water valve hookup is located behind condenser fan in back of refrigerator. Note: Foam insulation is very energy efficient and has excellent insulating capabilities. However, foam insulation is not as sound absorbent as previously used fiberglass insulation.
