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

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. 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.

Clean and cold!

Sir shops a lot 1/17/2022

Clean and simple fridge which is just what we wanted. Tons of space for a top freezer. The stainless doesn't print much at all. Keeps the food cold and the light lights everything up well. Would recommend

Doesn't stay cold

Sarah825 1/11/2022

Bought this and it never stayed cold enough even on the coolest setting. We've exchanged it for and 18 cu. feet and so far it's doing okay. They both make loud knocking noises that can be startling. Very beautiful design just needs the kinks worked out, obviously.

Worse refrigerator purchased

Vicky 1/4/2022

I bought this 1 year and 3 months and only three on out of warrantee and the door beeps as if it's opened. Sent Best Buy repair and they said it was electrical and could not access to repair. Samsung repair was out three weeks with $100 to evaluate. Will just need to buy a new one. Piece of junk! I have two kitchen of Samsung appliances. Will not do that again because they are making them to fail before warrantee. I asked for compensation for a new and no option there.

judgmentcenter 1/3/2022

This is a little larger than my prior top mounted freezer/refrigerator which is what I wanted. The freezer and refrigerator BOTH have their own temperature controls. They also BOTH have their own light. The ice cube maker works well too. I bought this directly from Samsung.com as I also bought the S21 Ultra 5g also directly from Samsung.com This refrigerator/freezer was out of stock at the two main big box hardware/lumber stores and also the national electronics, but it was in stock at Samsung.com AND it was also on sale, which made it lower in price than anywhere else I saw on the internet or in person at the stores.

TERRIBLE CUSTOMER SERVICE!

lynn 4/26/2021

the refrigerator is fine except i ordered one with the hinges on the left. i received one with hinges on the right. the samsung delivery people did not fix it, the door could be switched. called customer service at samsung and they said sorry out of luck. i also ordered and paid for removal of the old refrigerator; again, delivery people refused to complete the service. very poor customer service!!!!!

The Ugly, the Bad, and the Good

PJP1 4/5/2021

ugly: removed the sticker from the freezer door, which left adhesive residue on the surface. not wanting to ruin the finish, i searched the internet for a solution. on a retailer's site, a samsung rep gave the following instructions: bar keepers friend and a soft cloth wiping along the grain of the surface. i followed the official instructions to a t. not only did adhesive residue remain, but it marred the stainless steel finish. i. am. livid. a $1,000 refrigerator and samsung couldn't have spent a few extra cents for a low-adhesive sticker? bad: ice cube output slow. fitting gallon size milk containers/tall items on shelves takes creativity. good: freezer and fridge hold the correct temp. compartments are spacious.

Awesome fridge!

Hungry hippo 2/25/2021

We have had this fridge for over 4 months now and so far it's been great. Space is big enough keep all of our groceries, might not be enough for a big family but we have plenty for room in both the freezer and fridge portion. Comes with ice maker as well but we decided not to install right now. Freezer works just as it should and it keeps everything fresh, love the light in both Sections.Love the tray portion of the fridge, good for cheeses and meats. Fridge is very quiet, read some reviews about it being too loud but no complaints at all! The color and look is very nice and high end looking. Easy controls. Worth the purchase and very good price.

Kelii 12/5/2020

Nikki 8/27/2020

This is a terrible refrigerator. The refrigerator stopped cooling after only having this for a month. After about 7 house calls for repair, the issue was never resolved. I finally received a refund, but this refrigerator is awful. Do not waste your time with this one.

Best refrigerator I ever owned

Kiri 8/27/2020

Having use this for a few months, I can honestly say it is the best refrigerator we ever own. Freezer & fridge has their own temperature control, crisper keep the fruit & veggie always fresh. upper sliding section stuff w daily breakfast items. It's roomy & freezer can be converted for more .love the ice maker feature. Stainless exterior are easy to clean. Energy saver too. It is our first Samsung appliance. Will be looking for other Samsung appliance in the future.

Terrible

NO Thanks 8/21/2020

i absolutely hate this refrigerator. unfortunately, it was a "covid" purchase, as my old fridge was dying during a lockdown and i had to buy something quickly. the only good thing i can say is that it keeps food cold. the led lighting is dreadful - it only illuminates the front of the freezer and fridge and it is like looking into a cave. the lack of split adjustable shelves means no flexibility whatsover in terms of how you can store food. recessed handles means that people grab the sides of the doors, or use the front of the doors for pressure to open them, and the fingerprints are completely visible. i never would have purchased this fridge if i could have gone into a showroom and seen it in person. terrible structure and poor lighting. if i could return it, i would.

Ice cream in freezer is hard as a rock even at low

CRCC 8/3/2020

It's been almost two years now and I don't know what to do. Even at the lowest setting, the freezer keeps the ice cream as hard as a rock! I have to bring down the ice cream to the refrigerator section for 20 t0 30 minutes before I can enjoy an ice cream.

Not bad fridge. Tough to clean parts

John 6/24/2020

Bought this model because it was one of the only ones that would fit into the existing space in an older home and still have enough volume for a family of 4. Wasn't really first choice, it was all we could do. Fridge and freezer work well. No complaints there. A bit loud at times, but not really that bad. Had a bag of chicken defrosting in fridge on bottom shelf and the bag sprung a leak. "Chicken juice" dripped all over the place. Raw chicken juice got under the crisper drawers and all down the side of the fridge. It also flowed between the glass part of the shelf and the plastic frame that holds the glass. Discovered then that there is no way to remove the glass from the plastic frame. So now I have a thin film of raw chicken sandwiched between the shelf glass and shelf frame. Best I could do is take the whole shelf into the shower and force water into that space to displace the contaminant. Can't say I'd buy this again knowing what I know now. I know it might sound unrealistic, but this really has soured my Samsung experience...

Big Al 4/13/2020

I bought this a few months ago, was not cooling so I had to call out service tech. He replaced the thermometer and a sensor system in the back of the refrigerator, It woks correctly now. It would not get below 40 degrees. when it was first delivered, turn it to coldest setting and it did not help. I have the stainless steel finish, it shows smudges and finger prints very easily and is soft so it scratches very easy. Hard to believe I bought a brand new unit and had to call for service the first week because it would not cool.

Don't buy appliances from a cell phone mfr

Peg2 5/16/2019

This refrigerator is 11 months old. We have had constant temperature problems and now the open door alarm will not stop. After doing all the troubleshooting is still going off. How poor must manufacturing processes and quality control be for a major appliance to completely fail after less than one year? We are a family of two. Completely unacceptable and Samsung service is the absolute worst.

Good Fridge So Far

dckent 3/4/2019

We needed a 33" fridge so our options were very limited. Also, the space in front is a little tight, so we were looking for something shallow. Counter depth would be ideal, but that limited us to basically 1 option and the interior space wasn't going to cut it. We ended up getting this fridge and are happy with it. Even though it's 3-4" deeper than the counter depth we looked at, it's an inch or so shallower than most bottom freezer options and with no handles, that helped even more. The extra 4 cubic feet inside is exactly what we needed. We weren't initially looking at top freezers but our size issues led us to that aisle, but we liked the clean, stylish look (for a top freezer) and loved saving $400 over the other models we were looking at. I do have to echo the other review about changing the door swing. I did it myself and was surprised at how complicated it was, including laying the fridge down on it's back for most of the process. I think it took me about an hour, but the instructions were very good and totally doable if you're a little handy. Just know what you're getting into (or plan to have an installer prepared to do it for you). We've only had it for a couple weeks, so not a lot to say about performance, but haven't had any issues yet. I surely hope not, considering the size saga I relayed above.

Installer Could Not Connect to Water Line

Vrin 7/3/2017

Comes with ice maker but was missing parts to connect to water line. Have to wait for part and then make another appointment to have it installed. Another day of waiting for installer to show up. Doesn't get that cold. Cold enough but has me a little worried as at the highest setting it is barely cold enough. Expensive for what it is - a basic top freezer refrigerator. My fault for paying the price.
