Zero Clearance Hinges

Less gap, more fridge

Designed to help your fridge sit nearly flush with your kitchen cabinetry, LG Zero Clearance Hinges allow the doors to open wide even in tight spaces and when placed flush next to your walls. Combined with slimmer doors and front-bottom ventilation that flows air through the front, this space-saving design helps reduce gaps around your fridge, maximise your kitchen cavity space and give you more flexibility when choosing the right fridge for your next home.*

FAQ

What to consider when buying a fridge freezer?

'When choosing an LG fridge freezer, you may consider key factors like storage space, energy efficiency, and smart cooling technology.
LG’s smart solutions help maximise storage efficiency while keeping your food fresh.

Look for features like DoorCooling+™ to help cool items in the door quickly, or high star rating fridges to support energy savings.

What size Fridge Freezer do I need?

The right Fridge Freezer size depends on your household and storage needs. As a general guide:

-Bottom Mount or Top Mount fridges, with a capacity of 304–387L, may suit ideal for 1–2 people.
-Slim french door models, with 506–530L, may suit families of 3–4.
-For larger households, multi-door or French Door models, with 635–750L of storage, are a good choice.

Consider how often you shop, the amount of fresh vs frozen food you store, and your available kitchen space when selecting the appropriate capacity.

How do I change the temperature setting on my LG Fridge Freezer? 

Use the control panel on the door or inside the fridge to set the desired temperature for your fridge or freezer. On supported models, you may also use the LG ThinQ app on your smartphone to change the temperature setting remotely. 

What does it mean for a fridge freezer to be frost-free?

Frost forms when water vapour hits ice-cold cooling coils, then condenses into water, which immediately freezes. A frost-free fridge uses a timer to regularly turn on a heating coil around the cooling coil to melt the ice, automatically preventing frost buildup.
