HS Steel Series
MR-HS421EX-MB-A
Designed with modern homes in mind, the MR-HS421EX-MB-A 421L Bottom Mount fridge features a sleek matte black finish that blends with a wide range of kitchen styles. The 50:50 two-door design that more aligns with standard Australian benchtops supports a balanced, built-in appearance. With innovative cooling functions like Soft Freezing and Select Zone, plus ample freezer space, this model delivers premium performance and smart storage flexibility.
A 50:50 layout design with zero compromise
The Sterling Dark Silver fridge offers a sophisticated steel exterior that adds a contemporary touch to any kitchen. Its 50:50 door design integrates seamlessly into most cabinetry and aligns more with standard 900 mm kitchen benchtops for a balanced and modern aesthetic. The External LED Control Panel provides a convenient way to adjust temperatures and control modes without opening the doors, improving cooling efficiency and ease of use. Built for both style and practicality, this Sterling Dark Silver bottom mount fridge blends premium design with convenient features, making it a perfect fit for modern kitchens.
The Select Zone offers adaptable storage with two cooling modes. Soft Freezing mode preserves food at about -7°C, keeping items firm but not fully frozen, ideal for slicing meats, scooping soups, or preparing meals in advance. Switching the Select Zone to Chilling mode sets the temperature to around 0°C, the same as the Chilling Zone. This increases fresh food storage space by 22L. The dedicated Chilling Zone is perfect for storing dairy, seafood, and deli items at about 0°C, helping maintain their freshness and texture. The Fresh Box VitaLED helps prevent food waste by keeping fruits and vegetables crisp longer, slowing the wilting process.
This bottom-mount fridge offers practical storage for everyday use. The top and middle tempered glass shelves can be raised or lowered to accommodate taller items, making fridge organisation simple. The 50:50 two-door design provides a larger freezer section, ideal for storing frozen meals or bulk items. A dedicated Chilling Zone keeps deli meats and dairy at about 0°C, helping maintain freshness. The Automatic Ice Maker is easy to use and requires no plumbing. Just fill the removable water tank for a consistent supply of ice, ready when you need it.
A modern look for a modern kitchen - the 50:50 layout design integrates into most existing cabinets and aligns more with standard kitchen benchtops (900 mm).
Increased freezer space for better storage and organisation, particularly bulk frozen food purchases and ready meals.
Features two main modes: Soft Freezing and Chilling, with four temperature settings ranging from approximately -9°C to 0°C.
Customise the temperature based on your needs - chilling is ideal for storing foods like sausages, deli meats and cheese, and Soft Freezing keeps food ‘softly’ frozen.
Available in the Select Zone, soft freezing allows food to be frozen for up to three weeks in a ‘soft’ state at about -7º C. This means food, like meat, soup, and sauces, can be more easily cut, divided or scooped without thawing.
There is no need for a separate plumbing connection. The removable water tank can be filled with water and the Ice Maker is ready to go! All the parts are completely washable.
Avoid food wastage and properly store your produce with the VitaLED - it slows down the wilting process, keeping your fruits and vegetables crisp and fresher for longer.
Ideal for storing processed food such as sausages, deli meats and dairy products, at about 0°C.
A fridge that smells clean and fresh! The Blue Catalyst Deodoriser has an inorganic antibacterial which helps reduce any odours.
The top and middle tempered glass shelves are designed to move up and down, making it ideal for accommodating taller items. Upgrade your storage space with this easy-to-use feature.
With different temperature points in the fridge, this technology efficiently cools all food, even in hard-to-cool places such as filled door pockets.
The Refrigerator and the Freezer Compartments have separate Door Alarms which sound when open for over a minute.
The LED light will illuminate your refrigerator while being energy efficient.
Allows you to control the temperature settings and operation modes without opening the fridge or freezer doors, saving time and energy.
Mitsubishi Electric Inverter refrigerators are backed by a comprehensive 5 year parts and labour warranty and a 10 year parts warranty on the Inverter compressor. See the website for full Terms and Conditions.

A Bottom Mount fridge has the freezer below the refrigerator compartment, making fresh food stored at the top easier to access. This layout reduces the need to bend down when reaching for everyday items and supports a more natural posture during use. It’s a convenient and ergonomic option for everyday kitchen use.
The HS Steel Series Bottom Mount fridges come in three contemporary steel finishes:
Each option delivers a refined, minimalist look to suit modern Australian kitchens.
If you’re after a glass-front alternative, the HGS Glass Series is available in:
These sleek glass finishes offer a premium, high-gloss aesthetic, perfect for a more contemporary design statement.
The Top Mount fridge has its freezer compartment at the top and the refrigerator below, following a more traditional design. In contrast, a Bottom Mount fridge reverses this layout, positioning the refrigerator at eye level for better accessibility.
The main difference between a Top Mount fridge and a Bottom Mount fridge is the position of the freezer compartment. In a Top Mount model, the freezer sits at the top of the unit, with the fridge section underneath. This is a more traditional layout. A Bottom Mount fridge, on the other hand, places the fridge at eye level and the freezer below, making it easier to access fresh food without bending down. This design supports better ergonomics and everyday convenience.
The Mitsubishi Electric MR-HS421EX-MB-A Bottom Mount fridge combines advanced cooling technology with a refined steel finish, delivering both performance and style. Key features include:
The Automatic Ice Maker in this bottom mount fridge is designed for convenience. It operates without plumbing. Just fill the removable water tank, and the fridge takes care of the rest. All parts of the ice maker are easy to remove and clean, helping you maintain hygiene without hassle. There’s no need for expensive filter replacements, making it a cost-effective and user-friendly feature for daily use or entertaining.
You can use the Mitsubishi Electric Fridge Finder App to explore models that suit your lifestyle, space, and design preferences. The app asks a few quick questions to guide you to the best Mitsubishi Electric fridge options for your needs.
Once you’ve found a model you like, the app’s VR Photo feature lets you visualise the fridge in your kitchen. Just take a photo of your space, outline the fridge cavity, and the app will overlay realistic product images so you can see how different models, colours, and styles will look in your home.
Available for iOS devices.
