A large number of consumers and appliance reviewers agree that the Kenmore Top-Freezer Refrigerator 6898 is the quietest refrigerator available as of 2015. They note that the only way to hear the model running is to stand directly next to it.
One reviewer wrote that the Kenmore Top Freezer Refrigerator 6898 is so quiet it makes hardly any noise at all. The model defies convention in that generally reviewers find bottom-freezer and side-by-side refrigerators to be the quieter models. The Maytag French-Door Bottom Freezer Refrigerator, for example, is rated to be nearly as quiet as the Kenmore.
The LG brand is generally known for its quiet line of refrigerators. LG's compressors complete their cooling cycle much more quietly than most competitors by using what the company calls a "soft start regulatory system." Samsung's Chef Collection models also earn high ratings from consumer review publications for their quiet operation, as do the Whirlpool WRT771REY and Bosch Linea 800 B22CS80SN.
Features that contribute to noisy refrigerator operation include ice-makers and self-cleaning freezers. The quietest models as reviewed by consumers and professional reviewers range in price from the least expensive to far more costly high-end models and are available in a variety of sizes.
