InstaView™ Door-in-Door®

InstaView™ Door-in-Door® has a sleek mirrored glass panel that illuminates with two quick knocks, allowing you to see inside the easy access compartment without ever opening the door, reducing cold air loss to help keep food fresher longer.

Auto Open Door™

Auto Open Door™ feature is a smart sensor detector at the foot of the refrigerator that opens the door automatically. Just step on the "Door Open" light projection on the floor in front of the refrigerator and the door gently opens.

Auto Open Drawer™

Freezer drawers glide out automatically, and gently, in response to opening the freezer doors, providing easy reach. Drawers seamlessly glide back in response to closing the freezer doors.

Textured Steel™ Finish

Full stainless steel body with a scratch-resistant textured finish makes for an impeccable exterior design, enhancing its minimalist style to the fullest.

Stunning Yet Durable Finish

The full stainless steel body with a scratch-resistant textured finish brings a clean and modern aesthetic to your kitchen and withstands all flaws.

The Finest Black Diamond Sheen

The Knock-On Magic Space door is made of Belgian black diamond glass, and emits light of a uniquely alluring hue.

Custom Chill™ Pantry

The wide and deep versatile pantry is available with different temperature settings for storing a wide range of foods from meats to fresh produce.

FRESHShield™ Cooling

Cold air is automatically released from ducts located at the top of the refrigerator to form a cold air barrier.


By analyzing usage patterns, ThinQ® delivers an optimized and tailored user experience, from ramping cooling performance and ice making during peak times to conserving energy during times of inactivity through the ThinQ® App.


Premium LED lighting under each shelf offers a brilliant view of refrigerator contents.

Platinum Fresh Wall

Stainless steel interior helps maintain cold air while providing an upscale look with premium interior design.

Can you use the lower part as a refrigerator and not a freezer?  What is the highest temperature the freezer can be set at?

Asked by: JamesKC
You cannot use the freezer as a refrigerator compartment in the ENERGY STAR® Qualified LG SIGNATURE 31 cu. ft. Smart Wi-Fi Enabled InstaView™ Door-in-Door® Refrigerator, Model # URNTS3106N. The freezer temperature control ranges from -6°F to 8°F (-21°C to -13°C). The recommended temperature setting for the freezer compartment is 0°F (-18°C)...^Ivan
