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. Please consult a sales associate about delivery options.

Nice Looking

Submitted by Triton - 3/26/2020

Got this Frig about 3 months ago. Had to have service person check it out since it was not cooling below 36/38 degree. He replaced a panel & sensor in back of frig. Since that repair it seems to be much better.

Submitted by 4Rudys - 3/25/2020

Looked great and was spacious HOWEVER broke 2 months after the warranty expired. It was almost impossible to find someone who dared to mess with a Samsung refrigerator.. ended up being cheaper to buy a new one. Don't waste ur money!

Disappointed with some features

Submitted by RangerMomCOS - 1/2/2018

I was very excited to be replacing my old, inefficient refrigerator. I really wanted to love this new one. I had not seen it in the store, but I looked at online photos carefully to compare it to other models. I didn't care about the "Stainless Steel" finish but wanted a black model, so I went with the black stainless. (I put "stainless steel" in quotes because it is not real stainless steel. True stainless steel is not magnetic, yet the fridge door is magnetic.) Regarding the features: 1. It is dark. The light is positioned in the front, which casts shadows towards the back. 2. The shelves are adjustable, but there are not many height options, so I have really had to change the way I store my food, and I'm not thrilled with the arrangement. 3. The facade of the fridge is FLIMSY and SCRATCHES EASILY. We had to reverse the hinges for our space, and, in the process, the freezer door got scratched badly from an object that was not very sharp. Now my brand new fridge has major (albeit cosmetic) damage. I suppose the plus side of the magnetic surface is that I can now hide the scratches behind magnets and papers.

Not cold enough...

Submitted by JimR2281 - 7/29/2017

From day one this fridge doesn't cool like it should it! Even at its max settings the fridge temp ranges from 39-45 temp swings and this is with no one opening it for over 12 hrs. The lighting is very poor and it doesn't shine inside the fridge just at the front of the shelf leaving it dark inside. The shelf's fog up if the door is open for more than 30 seconds at a time making it even harder to see inside the all ready dim fridge. As for the color the black stainless is GRAY not black like other brands. Last time I but a new model with out seeing it in person..

Not as advertised

Submitted by bamwjj - 6/20/2017

I bought the stainless steel version of this and on Home Depot's website it says it has a fingerprint-proof coating to help prevent fingerprints and smudges. I purchased the identical model from Lowe's and called Lowe's customer service to confirm this model does have this coating and was told yes and that she found it in the user manual. I now have the refrigerator in my home with prints covering it and when I call Samsung, the lady says it does not come with a finger-print proof coating and they can't help what Home Depot put on their website or what told me. The lady was very nice, but nonetheless I now have a refrigerator that is not what I thought I was ordering. I might return it as this was the main reason for this purchase. Very disappointed.
