Combination microwave

Heat, roast, crisp and brown as you would with a large conventional oven. This Smeg SF4390MCX Built-in Combination Microwave provides you with microwave energy, a grill and fanned hot air so that you can prepare anything you need with quick and perfect results.

24 automatic cooking programs

Focus your energy on other aspects of your busy life and let the SF4390MCX do the cooking. Simply enter the food type, quantity and desired cooking, and the oven automatically goes to work for you by selecting cooking function, time and temperature.

Flatbed and multi-layered cooking system

With this Built-in Combination Microwave's flatbed, you enjoy a lot more flexibility and space to cook various foods at once.

The multi-layered cooking system ensures that if you are making a curry and a dessert at the same time, there'll be no flavour transfer between those foods.

Eclipse glass

This Smeg oven features special black glass that stays dark when not in use, and then becomes transparent when your combination microwave is at work, giving you an enhanced view of the cooking in action.

Enamel liner and Vapour Clean

The SF4390MCX has a special enamel coating that makes it difficult for spills and splutters to stick to its surface, making cleaning a breeze.

When you need an extra hand cleaning, the Vapour Clean function uses steam from the base of the oven to lift food spillage.


Liven up your microwave cooking with our range of microwave-safe accessories. Whether you need to warm up your soup for lunch or steam rice and vegetables for dinner, you'll find something to help you create exciting meals in your microwave.

Order online and collect in store

Order & Collect ­­– The majority of our stores are now open and offering a collection service, allowing you to safely order online and collect from store contact-free.

Our stores with parking available can offer a Drive Thru collection experience using the parking bays clearly marked outside the store. Here’s how it works;

  • Once you’ve had confirmation your order is ready to collect, drive to the store.
  • When you’ve arrived, click on the link in your confirmation email to let our team know.
  • One of our colleagues will put your order in your car boot.
Stores which DO NOT have parking outside, can only offer a safe Walk Up service. For large items we would not recommend using this service. Why not consider using our fantastic 2-man delivery service instead?
