Learn the new sounds of your Viking refrigerator to know what normal is for commercial-quality appliances in the home. Sounds emanating from a Viking tell you the refrigerator is working properly. Whirring fans and rushing air sounds from the refrigerator and freezer are normal and will cycle on and off. The evaporator and heat exchanger systems will gurgle, emit a popping noise or sound like water at a roiling boil. The defrost heater may make sizzling, hissing or popping sounds. The compressor emits a high-pitched hum or pulsing sound. If you have an ice maker it may buzz as the water fills and it will still make the noise if the water is not yet connected so long as the ice maker arm is in the "On" position.
Confirm that the refrigerator is receiving power first, if it does not seem to work. A fuse or circuit breaker could have blown or a light switch that controls the power outlet could have been accidentally turned off.
Ensure that the defrost tray, positioned at the underside of the refrigerator, is positioned on perfectly level ground so that it will fill with water but not overflow in hot and/or humid weather.
Check that the light bulbs are fresh and no circuits or fuses have been blown when the interior refrigerator lights fail to turn on when the door is opened.
Recognize that the refrigerator main motor will run longer and more frequently on hot days or when ambient temperatures in the home are kept higher, when the doors are opened frequently or left open for extended periods or when large amounts of food or warm food have been added. Reduce the run time by controlling or limiting these factors.
Correct slow water dispensing or hollow or small ice cube formation in refrigerators with dispenser features by boosting water pressure. Do this by turning the water supply valve at the rear of the refrigerator to its fully open/on position.
