You’ll find that the LG 635 Litre Side-By-Side American Fridge Freezer – Matte Black aims to combine high capacity with smart cooling technologies and a bold aesthetic for modern kitchens. In this review, you’ll get a thorough look at what this model offers, how it performs in daily life, and whether it matches your needs and habits.

What this model promises

LG markets this fridge as a large-capacity, stylish side-by-side unit with advanced cooling and smart features designed for family-sized storage needs. You should expect strong temperature control, flexible storage, and features intended to preserve freshness for longer, along with a premium matte black finish that blends with contemporary kitchen styles.

Design and build quality

You’ll notice the Matte Black finish first — it’s meant to look sleek and high-end while hiding fingerprints better than glossy surfaces. The build feels solid and substantial when you open and close doors, which is important for a large appliance you’ll use multiple times daily.

Exterior look and materials

The Matte Black exterior gives the fridge a modern, upscale vibe that works especially well with darker cabinetry or stainless steel fixtures. LG typically uses durable metal panels and reinforced door seals on models like this to add longevity and a premium tactile feel.

Interior layout and finish

Inside, you’ll find a logical layout with adjustable shelves, dedicated crisper drawers, and door bins sized to hold bottles and condiments easily. The internal surfaces are usually designed for easy cleaning, with LED lighting that brightly illuminates the interior so you can quickly see where things are stored.

Capacity and storage flexibility

With 635 litres of total capacity, this model is designed for large households or for anyone who likes to stock up on groceries. You’ll appreciate the generous space in both the fridge and freezer compartments for bulk shopping, meal prep, or entertaining.

How the space is divided

The side-by-side format splits capacity between fridge and freezer for quick access to both chilled and frozen items. The layout often includes adjustable tempered glass shelves, door bins that accept tall bottles, and multiple drawers, so you can configure the interior to suit tall platters or large containers.

Practical storage tips for this size

If you use bulk-buying or meal-prep strategies, you’ll find the space makes organizing straightforward: dedicate zones for dairy, drinks, leftovers, and frozen meals. Consider using clear storage bins for small items so you don’t lose things behind larger packages.

Cooling technology and freshness features

LG usually equips its large fridges with technologies designed to maintain stable temperatures and minimize both frost and odor transfer. You should expect features that focus on even cooling and reducing the frequency of manual maintenance.

Inverter Linear Compressor

An Inverter Linear Compressor is commonly used in LG models to deliver quieter operation and more precise temperature control than traditional compressors. This helps reduce energy consumption and keeps temperatures steady, which preserves food quality for longer.

Multi Air Flow and DoorCooling+

Multi Air Flow systems distribute cool air through multiple vents, helping keep consistent temperatures at all shelf levels. DoorCooling+ accelerates temperature stabilization, especially after the door opens, so items near the front are chilled faster and more evenly.

Smart features and connectivity

LG often includes smart connectivity on its higher-end models, letting you monitor and control settings via a smartphone app. If you like having remote access and push notifications, these functions can be really useful.

ThinQ (smart app) compatibility

ThinQ (or SmartThinQ) lets you check temperatures, receive alerts, and even run diagnostics from your phone. You’ll find that using the app can simplify troubleshooting and help you stay on top of maintenance with less hassle.

Voice assistant and control options

This fridge may support integration with popular voice assistants, enabling hands-free commands like checking temperature settings. These small conveniences can make a difference when you’re busy cooking or entertaining.

Ice and water dispensing

Many side-by-side LG units include a built-in water dispenser and ice maker, which are convenient during hot months or when you have guests. You should verify whether this specific model includes a plumbed water line or a refillable reservoir, since installation options differ.

Ice maker performance

If included, the ice maker typically produces a steady supply of ice and often has a quick-freeze option for faster production. You’ll want to know where the dispenser sits on the door and whether the unit produces cubed or crushed ice, depending on your drink preferences.

Water dispenser and filtration

A plumbed water dispenser delivers chilled water on demand, but you’ll need access to a water line and may want to install a filter for improved taste and odor removal. A filter replacement schedule should be observed to keep water quality high.

Energy efficiency and running costs

Large fridges consume more energy than smaller units, but advanced compressor technology and better insulation can help mitigate running costs. You’ll want to consider how the fridge’s energy usage fits within your household budget.

Typical energy-saving features

Inverter compressors and efficient insulation reduce overall power draw while maintaining temperatures. Smart features that allow you to monitor energy usage can also help you optimize settings to save on electricity bills.

What to expect on energy bills

Expect higher baseline consumption compared with compact models, but note that efficient tech can narrow the gap. Your actual running cost will depend on local electricity rates and how often you open the doors or load warm items.

Noise and vibration

You’ll probably use this fridge in a busy kitchen, so noise levels matter. LG’s inverter compressors typically run quieter and more smoothly than conventional compressors, making the refrigerator less intrusive in open-plan living spaces.

Sound level considerations

Noise output is influenced by compressor type and how the fridge is installed; on a solid, level floor noise is minimized. If you’re sensitive to appliance noise, look for decibel ratings and customer reports to get a feel for real-world performance.

Minimizing vibration and rattle

Proper leveling and adequate clearance behind the unit help reduce vibration and rattling. Keeping the fridge away from cabinets that amplify sound also improves your experience, especially during the night.

Cleaning, maintenance, and durability

Keeping a large fridge clean helps ensure both food safety and appliance longevity. The materials used in the interior and exterior influence how easy these tasks are.

Easy-clean surfaces and filters

Tempered glass shelves, removable bins, and flat door seals typically make cleaning straightforward. If the unit has an air filter (for example, a Hygiene Fresh+ system), follow the recommended replacement or cleaning schedule to maintain performance.

Longevity and warranty

LG generally offers competitive warranties, often with extended coverage on the compressor. Regular maintenance—like checking door seals and defrosting if necessary—can extend usable life and maintain efficient operation.

Installation and space considerations

Because this is a 635-litre side-by-side fridge, you’ll need enough space for both the unit and the doors to open freely. You’ll also need to account for ventilation clearance and, if applicable, a water line for the dispenser.

Placement and doorway access

Measure doorways, staircases, and lift access before purchase, as side-by-side fridges are heavy and bulky to move. Think about whether you’ll need professional delivery and installation to avoid damage.

Clearance and ventilation

Allow recommended clearance at the top and rear for proper air circulation. Placing the fridge too close to walls or cabinetry can impede cooling efficiency and increase energy usage.

Safety and food storage tips

You’ll want to store food safely to avoid waste and preserve flavor. Temperature zoning inside the fridge makes it easier to find the right place for different foods.

Best temperature settings

Keep your fridge at or below 4°C (40°F) and your freezer at -18°C (0°F) to slow bacterial growth and keep food safe. Use your fridge’s temperature display and smart app if available to monitor and adjust settings easily.

Organizing to minimize waste

Keep raw meats on the bottom shelves to prevent drips onto other foods, and use crisper drawers for produce to retain humidity. Label boxed meals with dates to help you rotate older items forward and reduce spoilage.

Pros and cons

You’ll want a straightforward list to weigh the main advantages and disadvantages before deciding.

Comparison to similar models

If you’re choosing between similar large side-by-side fridges, you’ll want to weigh features like capacity, smart functionality, finish, and price. You’ll also want to consider brand reputation and after-sales support in your region.

How it stacks up against other LG models

Compared with smaller LG models, this 635 L unit offers more storage for large families but requires more kitchen space. Against premium competitor models, it holds its own in cooling tech and smart features, with the matte black aesthetic making it stand out in a stylish kitchen.

When another format might be better

If you have a narrow kitchen or prefer a bottom-freezer layout for easier access to refrigerated items, a French-door or bottom-freezer model might suit you better. You’ll want a side-by-side like this model only when vertical divider convenience and balanced fridge/freezer access are priorities.

Who should buy this fridge

You’ll want to prioritize this model if you have a large household or if you entertain frequently and need reliable, spacious refrigeration. You should also consider it if your kitchen can accommodate a wide appliance and you value smart controls and a premium finish.

Ideal user profile

This fridge suits families of four or more, people who buy in bulk, and those who entertain often. It’s also a good fit for anyone who wants a bold, modern look (Matte Black) and appreciates app-based control and diagnostics.

Who might prefer a different option

If you live alone or in a small apartment, a large 635 L fridge might be overkill and consume more energy than necessary. Also, if your space is narrow or you need a fridge that’s easier to move through tight doorways, consider a different layout or smaller capacity.

Practical buying and ownership tips

Choosing the right fridge goes beyond the sticker price; you’ll want to consider delivery, installation, and ongoing costs.

Delivery and installation

Arrange professional delivery if possible — large side-by-side fridges are heavy and can be difficult to maneuver. If a water dispenser will be used, plan for plumber access to connect a water line safely and securely.

Long-term maintenance

Set reminders to replace water filters as recommended and clean door seals regularly to maintain an airtight closure. Periodically check the compressor vents and coils to keep dust from collecting and lowering efficiency.

Final verdict

If you need a large-capacity fridge with modern cooling tech and a stylish matte black finish, the LG 635 Litre Side-By-Side American Fridge Freezer – Matte Black is a compelling option. You’ll get practical storage, likely advanced cooling for longer freshness, and smart features that make managing temperatures and settings easier.

Bottom line

You should consider this fridge if you want a roomy, reliable, and elegant appliance that supports family life and entertaining. Make sure your kitchen can accommodate the size and that you’re ready for slightly higher energy use compared with compact alternatives. Check the exact retailer specifications and warranty details before purchasing to confirm fit and features for your region.

Frequently asked questions (short)

You’ll likely have some quick questions before buying — here are concise answers to common ones.

Does this model have a water filter?

Many LG side-by-side models include a replaceable water filter for the dispenser; check the retailer listing to confirm whether the GSXV91MCAE package includes a factory-installed filter or requires a separate purchase.

Is the ice maker plumbed or refillable?

This depends on the specific configuration you buy. Some variants offer a plumbed ice maker for continuous supply, while others use a refillable reservoir; verify the exact model listing or installation guide.
