The service manual when downloaded and printed out was clear and easy to read. The manual is complete with the schematic diagram and technical data. I occasionally require a manual and now having registered with this company I shall order from them in the future.

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)
