What people are saying

Rated 3 out of 5 by from 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......

Rated 5 out of 5 by from 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 '.

Rated 1 out of 5 by from 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

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&trade; Door along with the metal interior?

Asked by: Tater65
Greetings to you too Tater65! Thank you for your inquiry and for your interest in the ENERGY STAR&reg; Qualified LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView&trade; Door-in-Door&reg; 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&trade; Door along with the CoolGuard&trade; 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

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&quot;.

Asked by: colek
Hi Colek. Regrettably, the ENERGY STAR&reg; Qualified LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView&trade; Door-in-Door&reg; 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&quot; 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&quot; and has a 70&quot; clearance between the floor and the bottom of the cabinet, it will fit. It has a height of 70 1/4&quot; to the top of the door hinges, but again, if your cabinet has a depth of 24&quot;, that will not be an issue...^IFV

Does the software on this fridge get updated to stay current? As in, will it have the same software features as the upcoming Instaview ThinQ refrigerator (LNXS30996D)?

Asked by: Sean42
Hi Sean42. Your interest in our refrigerators is greatly appreciated. Regrettably, LG does not divulge detailed information on the software for its refrigerators and we cannot advise you about if the software features on this LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView&trade; Door-in-Door&reg; Refrigerator, Model # LUPXS3186N will be the same as those for the LG InstaView ThinQ&trade; Refrigerator, Model # LNXS30996D. What we can assure is that as long as the refrigerators are connected to your network, they can always receive software upgrades to keep them current. Both refrigerators are currently in production so we do not have the full specifications yet, but as production nears completion, the product information pages for each refrigerator will be updated to reflect their full specifications. Thank you for your patience and understanding...^IFV
