Product Details:


The LG's Slim SpacePlus™ Ice System
Provides the most shelf space while the innovative Door-in-Door Design allows quick and easy access to healthy snacks and frequently used items for the entire family.

Quick, Easy Access
Our exclusive LG Door-in-Door Design allows quick and easy access to healthy snacks, beverages and frequently used items for the whole family.

Door-in-door Fridge
Store items that you most often need for easier access

Super Capacity Refrigerator
Our largest capacity refrigerator. With 31 cu.ft., you can store more food than ever before. More storage space means less trips to the grocery store.

More Shelf Space
Most ice makers take up space in the fridge. Our Slim SpacePlus™ Ice System is located on the door, so you end up with more storage space on the top shelf--and you still have storage space on the door as well.

Fresher is Better
Our Smart Cooling Plus System maintains the optimal humidity and temperature levels in your fridge, which means your food stays fresher, longer. Meanwhile, a Fresh Air Filter removes odours and the Multi-Air Flow design means your food stays fresh no matter where you put it.

Call, Connect, Resolve
SmartDiagnosis™ uses self-diagnosing technology that can communicate 24/7 with LG customer service over the telephone providing you with comfort and reliability.

Peace of Mind
When you buy a refrigerator, you don't want to worry that it won't last. Because the Linear Compressor motor uses fewer moving parts and operates more efficiently, LG confidently backs the motor with a 10-year warranty.

Organized Freezer
The 3-Tier Organization™ Freezer System keeps food more organized and accessible. Now you can prioritize your favourite and most important items in your freezer so you can find anything fast.
