It offers a manufacturer-listed 44 L nominal capacity, but CHOICE reports 41 L of usable volume. Before buying one or replacing it in a kitchen, check the cabinet opening and arrange for a qualified electrician: the appliance is hardwired.
What the WMB4425SA is—and what its specifications tell you
Westinghouse describes the WMB4425SA as a built-in combination microwave. It uses microwave heating alongside convection and grill functions, so it is designed to do more than reheat or defrost. The manufacturer lists 900 W microwave output and 1,750 W each for grill and convection. Those are specifications, not evidence of how well it cooks compared with other ovens.

Westinghouse also lists electronic push controls, 10 programmed functions, three combination modes and child safety. Its product description says the grill can add a crisper result; that is the manufacturer’s description, not an independent test finding. Westinghouse WMB4425SA specifications

Westinghouse gives the cavity a nominal capacity of 44 L. CHOICE reports 41 L usable volume, with measured usable cavity dimensions of 23 × 41 × 43 cm. These figures use different conventions: use the usable figure and measurements when judging what will fit inside, rather than treating the nominal capacity as the space available for food.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.

Turntable figures also differ by source. CHOICE reports a measured usable diameter of 34 cm, while Appliances Online lists a 360 mm turntable. Because these are not presented as the same type of measurement, do not assume they are interchangeable. Check the manual or measure the accessory itself if a particular dish or replacement turntable needs to fit. CHOICE specifications · Appliances Online listing

Will it fit your cabinet, and does it need hardwiring?
The WMB4425SA is a built-in appliance with external dimensions of 595 × 568 × 454 mm. Those measurements describe the appliance, not the cabinet cutout or required clearances. Do not use them alone to decide that it will fit: consult the installation manual, check the required opening and ventilation, and compare those requirements with your cabinetry.

The unit must be hardwired. Appliances Online says connection must be completed by a qualified electrician, so include the electrical work in your installation plans. If your kitchen has only a standard plug connection at the intended location, do not assume the microwave can simply be plugged in.

Is the Westinghouse WMB4425SA discontinued?
Yes. CHOICE and ProductReview.com.au list the WMB4425SA as discontinued. Westinghouse’s page links to a replacement, but the reviewed page content does not establish that replacement’s model number. Current new-stock availability, used-market listings and prices have not been established here, so verify a seller’s listing and the appliance’s condition before making plans around a purchase.

A related model, the WMB4425SC, appears on Westinghouse’s site, but it is a different model. Do not assume it has the WMB4425SA’s dimensions, functions or installation requirements; check the specific product documentation.

What do the reviews establish about performance?
CHOICE has a model-specific review, but its public page does not reveal the expert rating or cooking-performance scores. The tests listed as member-only include cooking performance, ease of use, vegetables, defrosting, reheating, grilling, baking, roasting and visibility. Its public specifications are not a substitute for those results, so there is not enough public evidence here to call the WMB4425SA a strong or weak performer.

ProductReview.com.au displays two owner reviews. One reviewer, writing after a 2019 purchase, says the hardwiring requirement did not suit their kitchen. Another, whose purchase date was April 2018, describes the manual as vague and says they had not tried the roast function. These are individual experiences, not a reliable basis for judging typical performance or reliability. Appliances Online shows a 4.8 average from a small retailer-hosted review set; that rating is also customer feedback, not independent testing.

If you need a turntable, rack or another component, identify the exact model and part number from the documentation, then confirm compatibility and availability with the manufacturer or seller before ordering. Do not rely on appearance or a retailer’s general description alone.
How to assess one before purchase or replacement
- Confirm the exact model and condition. Since the WMB4425SA is listed as discontinued, verify whether a listing is for a new, used or refurbished unit and inspect the terms and condition that apply.
- Check the cabinet and installation manual. Compare the required cutout and clearances—not just the appliance’s external dimensions—with your kitchen.
- Confirm the electrical arrangement. The appliance is hardwired; arrange a qualified electrician and establish whether the existing installation is suitable.
- Match capacity to what you cook. Use CHOICE’s 41 L usable volume and 23 × 41 × 43 cm measured cavity dimensions as a guide, and verify dish and turntable fit where it matters.
- Verify support and parts. Check warranty terms, service options and the availability of any specific accessory or replacement part before committing.
For an alternative, compare only currently available built-in combination microwaves that meet your cabinet and electrical requirements. Check installation dimensions, hardwire versus plug connection, usable cavity and turntable size, heating functions and power, control complexity, warranty, service and verified stock. The WMB4425SA’s specifications alone cannot establish that another model is a like-for-like replacement.
