Hi we just purchased the 31 cu ft version , I was just wondering if anyone can tell me if the sides are in stainless steel ?

Asked by Yachtnutz August 3, 2019

No, the sides of this refrigerator are not stainless steel.

Greetings- I'm not sure the specific question has been asked or answered here yet. Will the LG Signature LUPXS3186N Model be available with the ThinQ™ Door along with the metal interior?

Asked by Tater65 July 16, 2019

Greetings to you too Tater65! Thank you for your inquiry and for your interest in the ENERGY STAR® Qualified LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView™ Door-in-Door® Refrigerator, Model # LUPXS3186N. Regrettably, LG has not made any announcements about any plans to release a version of this refrigerator that would feature the ThinQ™ Door along with the CoolGuard™ stainless steel panel interior that helps maintain cold air while adding a premium look. If LG has plans on that they will typically put out a press release announcing it...^IFV

Can this item come without the ice dispenser i have well water

Asked by brooklyn June 4, 2019

No, the ice maker is not removable and the refrigerator cannot be purchased without the ice maker. ^CP

Does this model come in any other sizes? I have a cabinet above my current refrigerator and the height at the top of the cabinet is 70".

Asked by colek May 29, 2019

Hi Colek. Regrettably, the ENERGY STAR® Qualified LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView™ Door-in-Door® Refrigerator, Model # LUPXS3186N does not come in other sizes. What you need is the measurement from the floor to the bottom of the cabinet above your current refrigerator and the depth of that cabinet. Typically, standard overhead cabinets are 12 or 13 inches deep except for microwave cabinets which are 15 to 18 inches deep so they can accommodate most standard microwave sizes. Cabinets placed above a refrigerator are also slightly deeper and typically measure 24 inches deep. This refrigerator has a height of 69" to the top of its case and the recommended installation clearance above the refrigerator is 1 inch so if your cabinet is a standard cabinet with a depth of 24" and has a 70" clearance between the floor and the bottom of the cabinet, it will fit. It has a height of 70 1/4" to the top of the door hinges, but again, if your cabinet has a depth of 24", that will not be an issue...^IFV

Will the door shelf behind the window accommodate a gallon milk container? I understand one would...

Asked by Nuke May 24, 2019

What microwave do you sell that matches this line? None of the others are listed as "textured steel" and no where around me has any of these in stock to look at, so I need to find a match before I purchase

Asked by Robelpa February 13, 2019

Regrettably, we currently don't have any microwave ovens that have the same Textured Steel™ Finish as the LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView™ Door-in-Door® Refrigerator, Model # LUPXS3186N...^IFV

Keeps Produce Fresh Longer!
When we rebuilt our home in 2019 we had the opportunity to create a deeper spot for a larger fridge rather than shallow counter depth which holds less. In searching, the LG Signature 3186 had the largest capacity in the market. The custom kitchen cabinets were designed around it, and we’re so glad we did! The advanced features, interior lighting and beauty made this one of our best decisions.

Not Built to Last
As with most appliances these days, this fridge just doesn’t seem built to last. We purchased this fridge 3 years ago and- despite being in love with its size, look, and functionality- we’ve had issues with the fan. Our produce is frozen at times (literally ice chips in peppers, frozen cucumbers, etc). The water line leaks, leaving a puddle inside the fridge, and the error code fR E displays often. We’ve had to empty it and “thaw it out”- thankfully we have an older, less fancy spare fridge to accommodate the food. For the price of this fridge, and the fact we haven’t even been using it for 3 years and have already encountered issues, I’m not sure it’s worth it.

I brought this 18 mts ago the ice maker start giving problems the fridge is making hissing noise and not cooling waiting for service for about 2wks

Love it, but...
I've had this fridge for about 8 months. While I do love it, I have to agree with some of the other reviews...the fact that you can't stand up a large bottle of juice is absolutely ridiculous considering how much this cost. Love the freezer drawers, insta-view door and especially the auto open feature.

Good product with great features
I recently bought this product from nearby showroom.

Having Issues
I received my first Signature refrigerator at the beginning of 2019. I absolutely love the spacious room inside. It will hold a lot of product. The swipe your foot to open the door is a great feature too. The freezer doors where the doors come out when you open is awesome. My freezer started frosting up. Found out that the seal was not sealing. Product is defective. LG offered to replace. Three months later and now the replacement product is having the same issue. The ice cube maker does not produce enough ice and there could be a little more room to place gallon containers upright. If you remove a shelf then the led lights don’t work on that shelf. I still can’t get my WIFI to hook up with this refrigerator. With all that being said, I really like the space and the stainless interior. I’m redoing my kitchen and LG does not make an oven/microwave combo to match the Signature series. I waited on ordering other products in hopes that this would come out. I am now waiting on another replacement fridge because it has the same defect as the original. Having issues with customer service from LG and Costco where I purchased. Still don’t have a delivery date for the new one. On the phone going back and forth trying to straighten out for hours. LG said they gave the order to Costco to replace. Costco said that they have not received anything. You know how it goes......

All I Could Want and More
We'very had the refrigerator for a few weeks now and absolutely love it starting with the ice and water. I like crushed ice and my husband likes cubes. Switching ice types doesn't put any of the prior selection into your glass. The filtered water tastes like the spring water I used to buy. The bins are great for organizing in both the cold and freeze sections and I like the way they lift out for cleaning. The freezer bins are large enough to hold a large turkey and, because they pull out, nothing is getting lost in the back. There is no wasted space. The quick through the door access section works great for grabbing items we use daily. My only complaints are the deli drawer at the bottom of the refrigerator section. You need to open both doors to access it. That should be 2 separate drawers like the rest of the refrigerator; and, the manual should have a larger font. Bottom line, every day, I say 'I love that refrigerator '.

Beautiful and every you'd want if it would run
I bought it less than a year ago, from the minute it was plugged in the water and ice maker wouldn't work, also the light would never shut off and the foot thing on the freezer didn't work either. We trouble shot the water and ice maker and replaced the necessary parts but still didn't work. When I called in to submit a service request they said there was not a tech in our area and they would have to call me back. Never a call. I called in again and got the same answer and was told I put on the list. Now it's 3 months since that request and the fridge and freezer have quit cooling. I'm not expecting the best outcome from the service request I submitted. I bought the extended 5 year warranty but don't know what good it does when no one can fix it
