What People Are Saying

Rated 4 out of 5 by from Counter depth for looks only, hope I get skinnier I wanted to get an appliance that would have form and fashion as well as functionality, and expected that from my recent purchase of an LG French door refrigerator. It meets the form and fashion, beautifully makes the kitchen and counter depth blends well. But can’t really pack it in with food. The shelves are shallow and I would need to carefully shop for food and packaging has to be a concern. The ice maker is great and not too noticeable loud. Door shelves are great for the drinks and liquids which I get a lot off. I can’t have my big holiday cake and eat it too, literally and figuratively.

Rated 5 out of 5 by from Intelligent Refrigerator I am enjoying all the features, especially the adjustable shelf . It allows me to put large containers on the shelf when needed and reverts back to a full shelf to store smaller items. It beeps when the door is left ajar too long which is perfect for my husband who gets a beverage and never fully closes the door. I also like the adjustable drawers in the freezer which enables me to put frequently used things like ice cream in easy reach. Love this refrigerator.

Rated 5 out of 5 by from Outstanding addition to our kitchen! Our old refrigerator of 12 years finally gave up. My wife and I started shopping and the moment she saw the LG she said this is it. The counter design and the interior features were exactly what she wanted.

Rated 5 out of 5 by from Works like a well-oiled machine! I've had my fridge for about 6 weeks now and its wonderful. Everything has been great. A little surprised about the square shaped ice cubes -- an interesting surprise. Took a minute to figure out the what side to put what items on based on what was used most frequently, but I got like I want it now. Excellent product.

We just bought this fridge and have a question about the doors. The right hand door swings easily until it gets within an inch of closing and then you have to give it a little push in order for it to close the whole way. Is this by Design

Asked by: ALM in PA
This is by design. The left door would close automatically, however, the right door has to be pushed all the way closed.

If I buy this refrigerator from Sears, do I still receive the linear 10 year warranty even if I decline the extra Sears warranties.

Asked by: simonesteger
The 10 Year Warranty is for the Linear Compressor in the ENERGY STAR® Qualified LG 21 cu. ft. Large Capacity Counter-Depth 3-Door French Door Refrigerator, Model # LFC21776ST and that is a Manufacturer's Warranty which comes with the refrigerator regardless of whether or not you have an additional warranty from Sears. The refrigerator also has a Limited Manufacturer's Warranty of 1 Year Parts and Labor, and 7 Years on the Sealed System. On both the 10 year warranty and the 7-year warranty, only the parts are covered but the labor is not covered after 1 year. You may want to review the Sears Warranty to see what it covers to determine if you should get it or not. Some Warranties cover what is not covered by the Limited Manufacturer's Warranty...^IFV
