This LG is considered a super-capacity refrigerator with a total capacity of 30.5 cubic feet. The top refrigerator portion has 20.5 cubic feet of storage space. Just for your reference, this is enough room to fit 50 gallons of milk. The icemaker is slim enough to sit behind two shelves in the left side door. Most french door fridges surrender the top shelf of the fridge to bulky icemakers, but this model gives you extra storage.

The freezer portion has 10 cubic feet of storage space divided into three drawers. The bottom drawer is the largest and has a divider splitting it into two sections. The two smaller drawers pull out above the large drawer.

The interior of the french door refrigerator has an LED lamp that illuminates the clear shelves and drawers. At a glance, you can see all your stored food items. The fridge has a total of four split shelves that you can move up and down to accommodate tall and awkward-sized objects. Made from tempered glass, the shelves come equipped with spill protection. This fridge also has two crisper bins for fresh fruit and vegetables, plus one extra bin that LG calls a bonus drawer. Additionally, it has a drawer that runs the full width of the compartment and is perfect for meats, cheeses or storing large platters for dinner parties. You can control the humidity in the two crisper drawers and the long drawer has three temperature settings.

In the right side door is a spot for storing items you commonly retrieve from the fridge. This is what's called the door-in-door compartment. The right handle has a button that, when pressed, opens to the small compartment that has enough space for condiments, cans of soda and a few gallons of milk. This door-in-door design is an added convenience and reduces the amount of cold air that escapes the fridge when you open it.

The french door refrigerator has a spacious freezer with three full-width drawers. The top drawer holds the ice bin, the small middle drawer is great for smaller items and the bottom drawer is the largest and deepest. A separate LED lamp lights the interior of the freezer compartment. The top internal baskets are made of clear plastic for increased visibility and the other drawers are opaque.

LG Electronics has a unique diagnostic tool to help with repairs. If something breaks, you can call LG and the customer support agent will instruct you on how to run the diagnostic test. Your french door refrigerator comes with a small speaker that will emit a tone that contains the necessary information to diagnose the situation. You will have to hold your phone up to the speaker, but then the customer service agent will be able to tell what needs to be repaired in your fridge.

External digital controls make it possible to see the LFX31945ST refrigerator's storage temperature, filter replacement dates and more. There are 10 digital sensors that monitor the refrigerator, freezer and room temperature. The unit vents cold air on each shelf to maintain an optimal food storage environment and has a filter to keep the air inside fresh. The fridge also sounds an alarm every 30 seconds if a door is open for over a minute. This feature not only helps prevent costly food spoilage but can also save energy expenses.

This fridge's appeal suffers slightly because it only comes in one color option, stainless steel, and it's not magnetic. However, stainless steel is a popular look complements most modern kitchens.

The space-saving Slim SpacePlus icemaker adds an innovative touch. The icemaker is capable of producing 3.5 pounds of ice a day, and the ice tray is easy to access behind a small door. The refrigerator's NSF-certified water filter delivers fresh-tasting water and ice that is free of impurities. The dispenser itself also accommodates tall containers.

This refrigerator has a linear compressor motor that uses fewer movable parts than many of the other products in our french door refrigerator review. This construction method helps keep the freezer quiet and efficient, and has fewer parts that could break down during long-term use. But just in case, LG Electronics covers this refrigerator freezer with a one-year parts and labor warranty, an extended seven-year warranty on the sealed system and a 10-year warranty on the linear compressor.
