    Overview

    The Westinghouse 44L Built-In Combination Microwave WMB4425SC brings microwave, convection and grill cooking together in one integrated appliance. With a generous 44L capacity and stainless steel finish, it is ideal for kitchens requiring more cooking flexibility without adding another full-size oven.

    More than a conventional built-in microwave, the WMB4425SC offers 900W microwave power alongside 1750W convection and grill functions. Choose from 10 programmed functions and three combination cooking modes to reheat everyday favourites or roast, bake and grill a wider variety of meals. Combining cooking methods can also help achieve browned and crisp results in less time than a conventional oven.

    For easier meal preparation, 13 Auto Cook programs take much of the guesswork out of selecting settings. Simply choose the appropriate program and enter the food weight, and the appliance calculates the required time, temperature and settings. Automatic frozen-food cooking options provide additional convenience when preparing meals straight from the freezer.

    Full touch electronic controls and an LED display make navigating functions straightforward, while 10 microwave power levels provide flexibility for different foods. A child safety lock helps prevent unintended operation, and the mark-resistant stainless steel exterior makes everyday maintenance easier. Combining versatile cooking with a fully built-in design, the Westinghouse 44L Built-In Combination Microwave WMB4425SC is a practical addition to a coordinated modern kitchen.
    13 Auto Cook programs

    As life gets busier, it helps to have some convenient shortcuts up your sleeve in the kitchen. With 13 Auto Cook programs to choose from, you can place your food inside the cavity, set the weight, and trust the microwave to select the appropriate power, cooking time, and temperature.

    Combination cooking

    Take your microwaving to the next level with the help of three combination modes. Choose between Microwave + Grill Cooking, Microwave + Convection Cooking, and Microwave + Grill Fan Cooking. The initial microwave heat will result in faster cooking times compared to a conventional oven.

    Seamless integration

    This microwave has been designed to seamlessly blend in with other appliances in the Westinghouse built-in family, helping you turn your house into a home.

    Child safety lock

    This appliance is safe for family households thanks to its child safety lock. When you activate this setting on the touch control panel, curious hands won’t be able to operate the unit by accident.

    Life Changing microwave
    [This review was collected as part of a promotion.] I so Happy With this new microwave the twin use is just so amazing easy to use.Wish i had it years ago
    Alex2026-06-22
    Absolute trash
    More useless as a microwave than anything I've ever seen. If you like part of your food literally charcoal and on fire, while another part is still cold and icy - this is the microwave for you. Completely useless, every use as a microwave does not work at all, and is a hazard. This should be removed from sale. Clearly the technology is not ready yet.
    I and C 772026-06-18
    Needs some tweaking for the price
    [This review was collected as part of a promotion.] Was a bit sceptical as to whether we would use all the features in this microwave as we are in our mid to late seventies and previously have only used a very basic microwave. The features on the panel are very hard to see and would benefit from lighting behind panel. At this point in time we require a torch to read them as the background is black. Our previous microwave does seem to have more power than this one but hopefully over time, we will be able to navigate the other features

    Hi there, is this unit suitable for under bench installs? If so, are there modified instructions. I want to install this unit under the kitchen bench not in a tower. Craig · 2025-03-07
    Hello Thank you for this product question. Yes, any single oven can be installed under the benchtop or placed in a wall installation. This model requires a 14-amp electrical connection and needs to be on a separate electrical connection from the powerboard to the oven location. On our website, we have included the user manual that you can download, which has installation details for your cabinet maker and electrician; please download this manual with installation information, pages 15 onwards. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
    Is there a SS trim kit available for this oven? Tony · 2024-01-14
    Hello Tony, Thank you for your product question. There is no trim kit available for this model because it is not necessary when integrating this unit into a cupboard. The dimensions of 595mm are comparable to the typical width of most 60cm ovens, making it suitable for installation either above or below an oven. This model can be installed as a standalone unit. For detailed installation instructions, please refer to the user manual, starting from page 15. I trust that this information will prove helpful as you shop with us at Appliances Online. Our Sydney office operates around the clock 24/7, and you can reach us at 1300-000-500. Colin Jones, Appliances Online

  • At Appliances Online, we're all about making the purchasing process as straightforward as we possibly can by taking away the stress that typically comes with shopping for cooking appliances like Westinghouse 44L Built-in Combination Microwave and Oven 900W Stainless Steel WMB4425SC and other items. Whether you're a complete kitchen newbie or the designated family cook, cooking appliances are absolute must-haves for all households. The thing is that they might just stop working all of a sudden after many faithful years of service. On the flip side, should your household setup shift, you may find yourself needing to upgrade to an appliance with improved efficiency or a bigger size to fit constant family changes. Replacing appliances can be overwhelming, as functions, technology and inclusions will likely have changed since your previous model. Here, there's no need to leave the comfort of your home just to spend a day hopping from one store to another, comparing features or researching replacements. With a vast and diverse array of over 8,000 different products you can select from, Appliances Online is the biggest online retailer of appliances and home essentials in Australia.

    Finding the right home essential or cooking appliance can sometimes feel like a challenge. This is especially true when you're balancing your budget with specific household needs. With countless models, features and price points, it's easy for the search to turn hectic. We recognise the importance of finding the right appliance in keeping your home running smoothly, and that's why we've made our services as easy and convenient as possible. We make it easier for you to shop with our Price Match Guarantee*. If you happen to see the same product being sold at a lower price by an Approved Retailer, just note the price and where you found it, and our helpful customer service team will verify and match it. We also offer our legendary service to make purchasing products like NEFF 45cm Compact Oven with Microwave Metallic Silver C29MR21Y0B-MS and Bosch Serie 4 60cm Slideout Rangehood DFS067A51A or any other essential much smoother. You'll receive all the guidance and details necessary to make a well-informed decision with us. This means that even if you're browsing for something different, such as items like Artinox Planum XL Draining Surface VPB2545 or Chasseur 5L Round French Oven Quartz 19989, you don't have to feel overwhelmed. You can count on Appliances Online to help you find your ideal product at a great price.
