Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Keeps breaking

Submitted by JMT6 - 4/12/2019

This refrigerator is beautiful elegant and organized. I want so badly to love it but I just cant. We bought the refrigerator in December of 2018 and were a bit apprehensive about spending so much on an appliance but the sheer beauty of the product the warranty and the freezer drawers swayed us. We thought if this thing lasts it will be worth the money. Less than two months later the compressor went out. LG sent out a service technician who replaced the compressor he was super nice and super professional. We thought it was fixed but it wasnt. It is now April 12th less than four months since purchase and our refrigerator has broken a total of five times. It works for a little while after each repair and then slowly warms to above room temperature all the while humming along as if it were working perfectly fine. With each break down we have had to throw out refrigerated and frozen food and taken time off work to wait for the repair technician. So in addition to the large amount of money we spent on the refrigerator itself we are easily out of an additional couple of thousand dollars between food and work hours missed. I am also starting to seriously doubt I will have any vacation time left to actually take a vacation this year. We have contacted LG and were told to submit an explanation via email that they can review and then they will decide how to resolve our issue. Like I said its really beautiful and I want to love it but for what we have spent we could of bought three other refrigerators that would probably still be working. If it worked the rating would be high. I will post a follow up if we can get a resolution.

This fridge makes my heart go boom boom

Submitted by Burtzilla momma - 3/10/2019

This fridge which me and my 5 little kids call Elsa the ice queen is a fantastic addition to our family if 7. Soooo much room I can fit 3 gallons of milk on one row- thats how deep it is The soft close drawers and huge and perfect for organizing your food. This beauty has many different compartments to keep your little items from cluttering your fridge or getting lost. The lighting is fantastic and we havent had any reconfiguration problems I read about. The water and ice maker are amazing Im a huge ice lover and I have yet to reach the bottom of the ice yet It even has a turbo ice function pretty sure thats not what its called but you get the picture so if you have a party coming up you will have non stop ice coming your way The tray at the bottom is also removable so its easy to clean.... major plus for a neat freak. MY FAVORITE PART The freezer Oh my good heavens This freezer makes my OCD heart leap for joy You open the doors and the drawers automatically slide forward. Then you can pick a drawer to side all the way out Gone are the days of a French Door chest freezer Gone are the days of getting frostbite every time I had to look for something Gone are the days of throwing out food that got left at the bottom because I refused to loose appendages to frostbite I was able to use each of the 6 drawers for each type of food Meat fruits veggies dairy grains and miscellaneous. Its soooo easy to organize find and enjoy food again. Its also easier to send my children or lets be honest my husband to look for food without the failed mission look on their face I also meal prep and freeze fruits and veggies from my garden and trees. I can fit a full on sheet pan inside one drawer Thats 6 pans of food I can freeze at one time Such a time saver. The door in door and auto door opener are fantastic features that lead to a lot of play time for the kids and dog. But they are definitely handy to mom as well. The ONLY thing I would change is the fridge doors. They are heavy and even when you close them you have to push on them to make sure they are closed. I wish the had a soft close option like the drawers inside. Overall Im so happy to be apart the LG signature family.

Lots of shelf room

Submitted by Richard AZ - 1/18/2019

I have had this unit for two weeks. Great refrigerator except for a few short comings. You only have one shelf for tall items and its the one behind the glass door. That shelf is for items you use everyday not for storage of tall items. They need one of their shelves to adjust half way and slide under to allow tall bottles to be stored. The other problem is they put the ice maker and water filter in the left side refrigerator door. The three shelves their are so narrow most items wont fit. They only can hole very narrow bottles. Also the top shelf behind the glass door is set so high you cant put anything bidder than a can of soda. Shelf should be adjustable. Freezer section is excellent. Well designed and latex out. The automatic shelves that come out make it so easy to find items you are looking for. This is a BIG refrigerator. Measuring the space in the kitchen for it is one thing. Trying to get it through the front door is next to impossible unless your delivery people are very patient and resourceful. After you take the doors off to try to get it in you have two 4 inch big hinges sticking out of the refrigerator that were holding the door. The manual talks about removing the doors but dorsnt talk about the hinges. These have to be removed or you gain nothing by removing the doors. Great if you have a double door entry. No problem getting it in. We like the looks of the refrigerator. No one had it in stock to look at so we had to decide to get it by looking at pictures.

Energy Saving and beautiful

Submitted by Kylimomma - 12/17/2018

Two cons: the front is not magnetic. So annoying. Cant put anything on the front of the refrigerator. Kids grades or coupons grocery lists. Nothing. Also when you knock twice to look at the quick grab it doesnt light up much so you cant really see what you want to grab so you just end up opening up the quick grab door to look at whats in there. Otherwise the two separate freezers save energy cuz I put smoothie stuff in one and frozen dinners in the other so youre not constantly opening the freezer for one thing. I love the automatic drawers that pull out for you. I love the automatic door open feature for when your hand is full. Wish the door would open a bit wider cuz you still have to grab the door and swing it open.

Perfect for my needs

Submitted by Diane83 - 10/17/2018

Perfect for my needs I really love this new refrigerator My hands are usually full when Im putting away groceries and the open door projection button is terrific. Yes the doors are heavy but not too heavy -- I just nudge it with my elbow. My little dog opened the door once - he had been watching me step on the projection and thought hed check it out. He stuck his paw on the light and the top door opened. The door shut back shortly thereafter and hes shown no further interest. Glad I dont have a great dane though I think being able to grab a bottle of water or can of soda from the front without opening the entire refrigerator is very helpful. The ice dispenser works nicely and quickly replaces cubes once dispensed. Ive used the pre-measured water amounts a few times but for my purposes this isnt needed. The fact that the drawers self close is really nice. I like the idea of the appetizer tray I havent used it so far other than to store some cheeses in it. I really really love the french door freezer with the six drawers and six side shelves I can see and find what Im looking for I love to cook and when I do I make enough to use in the future. With the LG french door freezer my freezer is no longer the abyss into which something goes and dies a slow and painful freezer death -- with the old giant bin I could never find what I was looking for unless I took everything out or a bunch of stuff out and put it on my already crowded counters - which is a pain so Id just buy fresh replacements. The bottom drawers are large enough to hold a medium sized frozen turkey. I also really like the fact that the drawers slide out when you open the door - Im tall with back issues so this is particularly convenient. I can organize and see and take out things that Im looking for so easily The doors are fingerprint resistant which is an absolute plus I like the look of the stainless steel on the inside. I love the idea of a fresh filter eliminating my need to keep an open box of baking soda inside which can get knocked over and create a mess. The crisper drawers are really roomy - I can store two large 17.3 cup produce savers in one drawer with ample room for other produce in front of it. I also love the fact that you dont have to take a million things out of the refrigerator to change the water filter - just the stuff on the side door one small shelf only. The water dispenser and ice dispenser in the door is wonderful and saves so much room Cons: I dont like that the under-shelf lights do not work if you move a shelf out of the predetermined position. The engineer who designed the shelf positions must not have any tall groceries. Salad dressings sauce bottles large size yogurt or milk cartons will not fit with the predetermined position. I adjusted the bottom shelf and now the lights do not come on - they only come on in one position. For really tall objects the only choice is to store it in the front door. Storing a cake on a pedestal in the refrigerator??? Forget about it. An open bottle of wine??? Nope - and it wont fit in the door if its a tall bottle and you have a stopper in it. I guess drinking more wine isnt a terrible thing. I also personally think the deli drawer should be larger. I wouldnt miss the appetizer drawer if it could result in the enlargement of the deli drawer. Bottom line I love the refrigerator and hope it lasts for many years.

Great Quality/Build

Submitted by spil - 5/19/2018

I bought this refrigerator a month ago am very happy with the capacity features and the service department. Two concerns though. The layout of the interior shelves cannot be changed to a different slot without deactivating the undershelf led lights. In order to store taller items Milk orange juice cartons etc you need to raise the lower shelf. When this is done the led light for that shelf is deactivated and the interior lighting is diminished. This could be corrected by designing push back half shelves or by designing all shelf positions for led light activation. Clearly a design oversight on a top of the line refrigerator. Also minor. The bottom rack of the door in door requires lifting milk across the wifi display and the top rack has a lip on the bin so items cant be remobed/accessed through the door in door.

great refrigerator. Quality inside and out

Submitted by darmes - 4/22/2018

We received this a few weeks ago. I love the stainless interior which is easy to keep clean and great against bacteria. The doors are sturdy and the interior lights make the inside bright and clean looking. There is no spot inside which seems to be colder then the other and finally the water tastes great from the new filter.
