Essential Microwave Oven Accessories and Where to Buy Them in the US

Why choosing the right microwave accessories matters

Think of your microwave like a small, fast-moving kitchen helper — and like any helper, it does a lot better with the right tools. The right accessories and replacement parts not only make your microwave more versatile, they keep it safe, efficient, and longer-lasting. Whether you’re replacing a worn turntable motor, fitting a trim kit for a new over-the-range unit, or swapping a magnetron, picking the correct accessory saves you time and can prevent expensive replacements down the road.

Core microwave accessories every homeowner should know about

Not all accessories are flashy, but the right parts make the difference between “meh” and “wow” performance. Below are the most impactful microwave accessories to consider stocking, keeping, or buying when you need a repair or an upgrade.

Replacement magnetrons (power source)

The magnetron is the heart of a microwave — it generates the energy that cooks your food. When it fails, your microwave won’t heat even if the lights and turntable are working. Replacement magnetrons like the Foreverpro WB27X10585 (compatible with many GE models) are common fixes. Choosing a quality replacement, whether OEM or proven aftermarket, will restore heating power and often extends service life by years. Always verify compatibility by model number before ordering.

Turntable drive assemblies and motors

If your food spins unevenly, stops mid-cycle, or the plate won’t spin at all, a turntable drive assembly (such as the Merrychef PSX203 turntable drive assembly) is often the culprit. These parts are relatively inexpensive, straightforward to replace, and there’s a wide range of sizes to match glass plates that typically range from about 10 inches to 16 inches in diameter. Replacing the drive assembly brings back even heating and prevents hot spots in meals.

Trim kits and over-the-range finishing pieces

Trimming an over-the-range microwave gives a clean built-in look and covers gaps between cabinetry. Trim kits such as the Frigidaire FFMOTK27LS 27-inch stainless steel kit are available to match common microwave widths — 24-inch and 27-inch being popular sizes for over-the-range installations. Trim kits are ideal when upgrading or replacing an older microwave and help maintain the aesthetics of your kitchen.

Turntable plates, rings, and rollers

Glass turntable plates, the supporting ring, and the rollers are inexpensive but wear out over time. Plates commonly come in diameters like 10 inches, 12 inches, or 15 inches. Having the right diameter is crucial: a mismatched plate can jam the motor or create instability. Replacing a cracked plate or worn ring is a fast fix and restores safe, even rotation.

Microwave racks, steamers, and specialty cookware

Want to broil, steam, or prep multiple layers at once? Microwave-safe racks and steamers expand what your microwave can do. Racks that fit inside turntables are typically a few inches high and let you cook two layers of food without blocking vents. Specialty cookware made for microwave browning or crisping can also expand functionality without needing an oven.

Door latches, hinges, and safety interlocks

Door components are safety-critical. If a door won’t latch or the microwave doesn’t start despite other parts working, the latch or interlock switches may be broken. Replace these parts promptly and use genuine or reputable aftermarket components to ensure the door seals correctly and safety circuits function as designed — don’t skip this even if the microwave “mostly” works.

Where to buy microwave parts and accessories in the United States

When it comes to sourcing microwave parts, you want a retailer that carries genuine parts, clear compatibility info, and reliable shipping or in-store pickup. Below are top retailers where many homeowners find the parts named above and related accessories.

Walmart — broad selection and value options

Walmart stocks a wide range of microwave parts and accessories, from replacement magnetrons and turntable drive assemblies to trim kits and plates. Popular items like the Foreverpro WB27X10585 magnetron (compatible with numerous GE models), Frigidaire 27-inch trim kits, and Merrychef turntable assemblies are often listed through Walmart’s online marketplace or available in-store. Walmart tends to offer budget-friendly aftermarket options as well as name-brand parts, making it a convenient first stop for many DIYers.

Amazon — massive selection and customer reviews

Amazon is a go-to for hard-to-find model-specific parts and offers the advantage of extensive customer reviews. Whether you need a 12-inch glass turntable or a rare magnetron, Amazon’s marketplace connects you to OEM sellers and reputable aftermarket brands. Look for listings that show specific microwave model compatibility and read reviews for fit and longevity before buying.

Home Depot and Lowe’s — appliances and installation-friendly parts

Home Depot and Lowe’s carry a mix of accessories and replacement components, and they’re particularly good for trim kits, racks, and larger installation items. These retailers also offer helpful online guides and in-store associates who can advise on fitment for common sizes like 24-inch or 27-inch trim kits. If you’re doing an installation or need a standard-sized part, these stores are reliable and widely available across the US.

Best Buy and appliance specialty stores

Best Buy often carries accessories for popular microwave brands and can be especially useful for built-in and over-the-range components. Appliance specialty stores and local repair shops also stock OEM parts and can order brand-specific components if needed. These sources are handy if you prefer buying parts verified by trained technicians.

eBay and specialist parts vendors

For discontinued models or rare parts, eBay and specialty online vendors can be lifesavers. You’ll find used, refurbished, and new-old-stock components such as vintage magnetrons or specific microwave door assemblies. Buy from sellers with solid return reputations and ask about part condition and compatibility before purchase.

How to identify the correct part for your microwave

Picking the wrong part is the most common setback in DIY microwave repair. Start by noting the appliance model number, usually on a label inside the door frame or on the back panel. Then match part numbers when possible — OEM numbers like WB27X10585 correspond to specific units. If you’re unsure, compare measurements in inches (diameter of plate, dimensions of trim kit, etc.) and check compatibility charts on retailer pages. When in doubt, take a quick photo of the existing part and consult seller listings or store associates.

OEM vs aftermarket: what to choose?

OEM parts are made by the microwave manufacturer and typically offer the best fit and safety assurance, but they can cost more. Aftermarket parts are often cheaper, and many are high quality, but you’ll want to read reviews and verify that the part is designed specifically for your model. For safety-critical components like door interlocks and magnetrons, many technicians recommend OEM or high-quality aftermarket options with strong reviews.

Installation tips — simple fixes anyone can do

Many microwave repairs are within reach for a handy homeowner. Replacing a turntable plate or ring is usually plug-and-play: just remove the old plate and set the new one on the rollers. Swapping the drive assembly or motor is a bit more technical but doable if you are comfortable removing the bottom access panel and working with basic tools; always unplug the microwave and discharge capacitors when working inside. For trim kit installation, measure cabinet openings in inches and follow the kit instructions to ensure a clean, flush fit. If a job requires soldering or capacitor work, consider a technician — safety first.

Safety reminders and electromagnetic considerations

Microwaves contain high-voltage components even when unplugged. If you don’t understand how to handle capacitors, magnetrons, or high-voltage circuits, stop and ask a professional. Also, use only microwave-safe cookware and accessories to avoid arcing or fires. If you ever hear unusual noises, smell burning, or see sparks, stop using the microwave and have the unit inspected. Replacing worn door latches, seals, and interlocks promptly keeps microwave radiation contained and your family safe.

Maintenance habits that extend microwave life

Simple maintenance goes a long way. Wipe spills after each use to keep vents and seals clear, check the turntable and ring monthly for wear, and clean the interior with a damp cloth and mild detergent. Avoid running an empty microwave, and be cautious when heating metallic-trim cookware. Regular checks in inches for plate flatness and ring integrity save you from sudden failures. A well-cared-for microwave can run reliably for many years.

When to repair vs when to replace

The decision to repair depends on the cost of parts, the microwave’s age, and safety. If a single inexpensive part like a turntable motor or plate ring fixes the problem, repair is usually the sensible choice. However, if the magnetron fails on a very old unit or the cost of parts exceeds roughly half the cost of a new microwave, replacement might be the better call. Also consider energy efficiency and features — a modern unit with better energy use and added functions can be a welcome upgrade.

Saving money without sacrificing quality

Compare prices across retailers — Walmart, Amazon, Home Depot, and specialty sites often differ on price and shipping. Look for verified sellers and read customer feedback. For trim kits and widely used parts, buying from a big-box retailer can be cost-effective. For obscure parts, specialist vendors or eBay may be the only practical option. In all cases, verifying model compatibility in inches and model numbers prevents wasted purchases.

Final checklist before you buy

Before clicking “buy,” make sure you have the microwave model number, exact measurements in inches if applicable (plate diameter, trim kit width), the OEM or aftermarket part number, an estimate of installation difficulty, and a plan for safe installation. This short checklist reduces mistakes and returns — and helps you get your microwave back in working order quickly.

Conclusion

Microwave accessories and replacement parts range from tiny rollers to major components like magnetrons, and each plays a role in keeping your microwave functional and safe. Retailers such as Walmart, Amazon, Home Depot, Lowe’s, and Best Buy provide broad selections, while specialty vendors and marketplaces can supply hard-to-find parts. With the right measurements in inches, the correct model number, and a careful buy-and-install approach, you can extend the life of your microwave, improve performance, and save money. Don’t underestimate the value of a well-chosen part — it can turn a tired appliance back into a trusty kitchen workhorse.
