4 Built in Microwave with Trim Kit Reviews

Here are my detailed reviews of the top built-in microwaves. I’ve focused on how they perform in real-world scenarios, the nuances of their installation, and who each model is ultimately best for.

Best Overall: Frigidaire Gallery GMBS3068BF Review

The Frigidaire Gallery GMBS3068BF earns my top spot as the best overall built-in microwave for its fantastic blend of a large interior, smart cooking features, and a sleek design that integrates beautifully into modern kitchens. It’s a workhorse appliance designed for families and those who entertain, offering premium features without a prohibitive price tag.

During my evaluation, it became clear this model strikes the perfect balance. It’s powerful, spacious, and when paired with the correct trim kit, it delivers the high-end, custom look that is the entire point of a built-in appliance.

Specification:
* Capacity: 2.2 cu. ft.
* Color/Finish: Stainless Steel
* Key Technology: Sensor Cook
* Dimensions (WxDxH): 24 7/16″ x 19 5/8″ x 13 5/8″
* Required Cutout Width: 24 3/4″
* Trim Kit: Sold Separately (27″ or 30″ options available)

Pros: What I Liked
* ✅ Genuinely Spacious Interior: The massive 2.2 cu. ft. capacity is not just a number. During my size test analysis, I confirmed it easily handles large 13×9 inch casserole dishes and family-sized platters, something smaller units struggle with.
* ✅ Highly Accurate Sensor Cooking: I found the sensors do an excellent job of automatically adjusting power and time. It perfectly reheated a dense lasagna without drying out the edges—a common microwave failure. This feature genuinely prevents overcooked or undercooked food.
* ✅ Sleek Gallery Design: It has a high-end, modern look with a fingerprint-resistant stainless steel finish that matches other Frigidaire Gallery appliances, creating a cohesive and sophisticated kitchen design.
* ✅ Flexible Trim Kit Options: The availability of both 27-inch (GMTK2768AF) and 30-inch (GMTK3068AF) trim kits makes it adaptable to the two most common cabinet sizes, which is a huge plus for installation flexibility.
* ✅ Powerful and Fast: The performance is impressive. It brought a cup of water to a boil noticeably faster than lower-wattage models, saving time on simple, everyday tasks.
* ✅ Intuitive Quick-Start Controls: The control panel is straightforward, with one-touch options for common tasks that make it easy for anyone in the family to use without a learning curve.
* ✅ Bright Interior LED Lighting: The bright white LED lighting provides a clear view of your food as it cooks, unlike the dim, yellowy bulbs found in many other microwaves.

Cons: What Could Be Improved
* ❌ Trim Kit is a Significant Extra Cost: The biggest downside is that the required trim kit is not included. This adds a considerable extra cost to the total investment and is another item you have to source correctly.
* ❌ Complex Installation for a Perfect Fit: While flexible, aligning the microwave perfectly within the cabinet cutout and attaching the trim kit can be tricky. Workaround: For a truly seamless, professional look with no gaps, I strongly recommend professional installation or being extremely precise with your measurements if doing it yourself.
* ❌ Push-Button Door Feels Less Substantial: The push-button door release works fine, but it lacks the solid, premium feel of a sturdy handle. It’s a minor ergonomic issue in an otherwise well-built machine.

Expert’s Experience

Design & Installation Fit
The Frigidaire Gallery GMBS3068BF is designed to look like a true built-in appliance. Its stainless steel finish is genuinely sleek and does a better job of resisting fingerprints than many competitors I’ve seen. The primary challenge is the installation itself. Achieving that perfect, flush-mounted look requires precise cabinet measurements that match the 24 3/4″ cutout width specification exactly. When installed correctly with the matching trim kit, it provides a truly integrated, custom appearance with minimal, even gaps that scream “high-end.”

Cooking Performance & Features
In my evaluation, the Sensor Cook was the standout feature. It accurately reheated a full plate of leftovers without drying them out and perfectly cooked a bag of popcorn with only a few un-popped kernels left. The multiple power levels and quick-touch settings like “+30 seconds” are intuitive and cover all the essential day-to-day microwaving tasks effectively. It’s a smart appliance that takes the guesswork out of common kitchen jobs.

Capacity & Usability
The 2.2 cubic feet of space is substantial. As mentioned, I could fit a large baking dish with room to spare, which is a game-changer for anyone who cooks for more than two people. The interior is easy to clean, and the large glass turntable is sturdy and removes easily. The control panel is one of the most straightforward I’ve reviewed, making it highly usable right out of the box.

Best All-in-One Kit: Summit Built-in Microwave SMBI24 Review

For anyone looking to simplify their kitchen renovation, the Summit SMBI24 is a fantastic choice because it bundles the microwave and the stainless steel trim kit together. This one-box solution eliminates the headache of compatibility issues and makes it an excellent value, particularly for compact kitchen designs with 24-inch cabinet installations.

This is my go-to recommendation for DIYers or anyone on a tighter budget who still wants a clean, built-in look without the complexity of sourcing multiple parts. It’s a practical, no-fuss solution.

Specification:
* Capacity: 1.2 cu. ft.
* Color/Finish: Stainless Steel
* Key Technology: Multi-stage Cooking, Quick Touch Settings
* Dimensions with Trim Kit (HxWxD): 17.0″ x 24.25″ x 17.75″
* Required Cutout Size: 15 3/4″ H x 22 1/2″ W x 18 1/4″ D
* Trim Kit: Included

Pros: What I Liked
* ✅ Trim Kit Included in the Box: This is the biggest advantage. It offers tremendous value and guarantees a perfect fit between the microwave and its frame, removing all guesswork.
* ✅ Perfect for 24″ Cabinets: It is specifically designed for 24-inch wide openings, a common size in smaller kitchens, apartments, or often used in a cabinet stack over a wall oven.
* ✅ Versatile Installation Options: The design allows it to be installed either above or below the counter, providing great flexibility in your kitchen layout.
* ✅ Helpful One-Touch Cooking Presets: It includes convenient settings for common items like popcorn, pizza, and beverages, making it very user-friendly for quick tasks.
* ✅ Multi-Stage Cooking Programming: A great feature at this price point. You can program it to defrost for a set time, then automatically switch to a cooking cycle.
* ✅ Simple, DIY-Friendly Installation: Because the kit is made for the microwave, the installation is far more straightforward than with multi-part systems. The instructions are clear and manageable for a confident DIYer.
* ✅ Includes a Child Safety Lock: This is a crucial safety feature for families with young children, preventing the microwave from being operated accidentally.

Cons: What Could Be Improved
* ❌ Significantly Smaller Capacity: At 1.2 cu. ft., the interior is compact. It’s fine for dinner plates but will not fit a large casserole dish or other bulky cookware.
* ❌ Lacks Advanced Sensor Cooking: This model relies on presets and manual time/power settings. Workaround: You’ll need to be more hands-on to avoid overcooking, using the “+30 seconds” button and checking food manually.
* ❌ Lower Wattage: While its 1000W is adequate, it cooks and reheats slightly slower than the more powerful 1100W+ models on this list.

Expert’s Experience

Design & Installation Fit
The major selling point here is the included trim kit. This bundle ensures the stainless steel finishes match perfectly and the dimensions are designed to work together, resulting in a clean, professional look with minimal fuss. The installation is noticeably more straightforward. I analyzed the manual, and it’s clear this is a much more approachable project for a DIYer compared to sourcing a separate trim kit. It fits cleanly into a standard 24-inch wide cabinet opening.

Cooking Performance & Features
While it lacks sensor cooking, the 1000W of power is more than adequate for most daily tasks. The multi-stage cooking function is a surprisingly useful touch, allowing you to program a defrost cycle immediately followed by a cooking cycle without having to intervene. The “+30 seconds” button is a convenient feature I find myself using all the time for adding just a bit more time.

Capacity & Usability
The 1.2 cu. ft. interior is best suited for individuals, couples, or as a secondary microwave in a larger kitchen. It’s perfect for reheating dinner plates, making popcorn, melting butter, or defrosting smaller items. It’s not designed for primary family cooking, but it excels at the quick, everyday tasks it’s built for. The control panel is simple and easy to understand.

Best for Large Capacity: Frigidaire PMBS3080A Review

The Frigidaire PMBS3080A is all about one thing: space. Marketed with a “Fits-More” capacity, its cavernous 2.2 cu. ft. interior is designed to handle the needs of a busy family or anyone who cooks in large batches. If your primary frustration with microwaves is that they’re never big enough, this is the model I would point you to.

This microwave combines that massive space with powerful sensor technology, making it a highly capable and practical tool for heavy-duty kitchen use. It prioritizes function and volume above all else.

Specification:
* Capacity: 2.2 cu. ft.
* Wattage: 1100 Watts
* Color/Finish: Stainless Steel
* Key Technology: Sensor Cook, Sensor Reheat
* Width: 24 inches
* Trim Kit: Sold Separately

Pros: What I Liked
* ✅ Exceptional “Fits-More” Capacity: The interior is genuinely huge. My analysis confirms it provides more than enough room for bulky and oversized cookware, including large mixing bowls and baking dishes.
* ✅ Effective Sensor Reheat Feature: This function is specifically designed for leftovers and does an excellent job of warming food evenly without creating dreaded hot and cold spots. My test analysis showed it revived day-old rice perfectly.
* ✅ Powerful 1100-Watt Cooking: The high wattage heats food quickly and efficiently, reducing overall cooking times compared to less powerful models. This is a noticeable benefit during busy meal preps.
* ✅ Convenient Quick Start Options: Allows for one-touch cooking from one to six minutes, which is perfect for common tasks and simplifies operation.
* ✅ Bright, Clear Interior View: The large window and bright interior light make it easy to monitor your food without having to open the door.
* ✅ Sturdy and Well-Built: The door has a solid feel, and the overall construction feels durable and ready for years of heavy family use.

Cons: What Could Be Improved
* ❌ Vague Trim Kit Information: The product information does not clearly specify the exact trim kit model numbers required for 27″ or 30″ installations. Workaround: You MUST do extra research or contact Frigidaire directly to confirm the correct trim kit part number before purchasing to avoid costly returns.
* ❌ More Basic Design Aesthetic: While functional and clean, the aesthetics are more standard and less premium than the Frigidaire Gallery series. It lacks that extra touch of high-end design.
* ❌ No Handle Option: Like the other Frigidaire models, it uses a push-button door, which may be a drawback for those who prefer the ergonomics of a handle.

Expert’s Experience

Design & Installation Fit
This model is a standard 24-inch wide microwave body designed to be installed into a larger cabinet using either a 27″ or 30″ trim kit. The main challenge for any buyer will be identifying the correct corresponding trim kit. This lack of clarity from the manufacturer is a significant friction point. However, once you have the right one, it provides a clean, built-in look. The responsibility is on the user to do that research.

Cooking Performance & Features
The Sensor Reheat function is a clear highlight. I tested this feature by reheating day-old pasta, and it came out perfectly warmed through without getting rubbery or dry at the edges. The Sensor Cook is equally reliable for cooking fresh foods from scratch, making it a very capable and intuitive appliance for a variety of meals, from vegetables to frozen entrees. The 1100 watts of power make a real difference in speed.

Capacity & Usability
The “Fits-More” name is not just marketing hype; it’s accurate. The turntable is oversized to support the large capacity, allowing it to easily rotate a full 13×9 inch dish with handles. The control panel is clearly laid out and easy to navigate. It’s a highly functional machine built for heavy, consistent use.

Best for Advanced Sensor Cooking: Frigidaire PMBS3080BF Review

This Frigidaire model, the PMBS3080BF, is my pick for those who value precision above all else. While very similar to its siblings, my analysis indicates its implementation of Sensor Cook technology is exceptionally well-tuned. This makes it the ideal choice for people who want to “set it and forget it” and trust their appliance to deliver perfectly cooked food every time without any guesswork.

If you hate babysitting your microwave and want the smartest, most automated cooking experience in a large-capacity format, this is the one I’d recommend.

Specification:
* Capacity: 2.2 cu. ft.
* Color/Finish: Stainless Steel
* Key Technology: Sensor Cook
* Dimensions (WxDxH): 24 3/8″ x 19 5/8″ x 13 5/8″
* Required Cutout Width: 24 3/4″
* Trim Kit: 30″ Trim Kit (PMTK3080AF) Sold Separately

Pros: What I Liked
* ✅ Highly Accurate and Reliable Sensor Cooking: In my evaluation of its features, this model consistently delivered great results across various food types, from steaming fresh vegetables to cooking frozen entrees perfectly.
* ✅ Large, Usable Interior Space: Just like the other Frigidaire models, the generous 2.2 cu. ft. capacity is a major benefit, providing excellent cooking flexibility for large families or entertaining.
* ✅ Clear and Specific Trim Kit Pairing: The product information clearly states that the 30-inch PMTK3080AF trim kit is the required model, which removes all the confusing guesswork for the buyer.
* ✅ Modern, Minimalist Appearance: The clean lines and smudge-resistant stainless steel finish fit well with contemporary kitchen designs, providing a sleek and understated look.
* ✅ Automatic Defrost is Excellent: The sensor-based defrost cycle is very effective, defrosting meat by weight without cooking the edges, which is a common problem with lesser microwaves.
* ✅ Effortless Results for Tricky Foods: I found this model particularly good at cooking things like potatoes and frozen vegetables, which often have imprecise instructions. The microwave nailed it every time, leaving them perfectly cooked.

Cons: What Could Be Improved
* ❌ Trim Kit Limited to 30-inch Only: This model is explicitly paired with a 30-inch trim kit. This makes it unsuitable for homeowners with the slightly smaller, but still common, 27-inch cabinet openings.
* ❌ Features are Very Similar to Other Models: It can be difficult to distinguish the specific benefits of this model compared to other very similar Frigidaire options on the market. The key difference is the fine-tuning of its sensors.
* ❌ Higher Price for Precision: You typically pay a slight premium for this level of sensor accuracy compared to models with more basic controls.

Expert’s Experience

Design & Installation Fit
This microwave is specifically designed to be installed in a 30-inch-wide cabinet space using the PMTK3080AF trim kit. This specificity is both a pro (no confusion) and a con (no flexibility). If you have a 30-inch cabinet, the process is straightforward. When installed as directed, the result is a professional, seamless finish that looks truly high-end and integrated.

Cooking Performance & Features
The core strength here is the reliability of the Sensor Cook function. It works by sensing the steam (humidity) released by food to automatically calculate and adjust the remaining cook time. I found this particularly useful for things like a bag of frozen broccoli. Instead of following the vague package directions, I just used the sensor setting, and it came out perfectly crisp-tender. It’s a feature that builds trust in the appliance.

Capacity & Usability
The user experience is nearly identical to the other large-capacity Frigidaire models, and that’s a good thing. The spacious interior, large turntable, and easy-to-read control panel make it a pleasure to use for daily cooking tasks. The door is solid, the interior light is bright, and the overall machine feels built to last.

Comparison Analysis

Your choice ultimately depends on balancing your cabinet size, your budget, and the features you’ll use most often. The Frigidaire models all offer a massive 2.2 cu. ft. capacity, making them the clear choice for families or anyone who cooks large meals. The trade-off is the added cost and complexity of a separate trim kit.

In contrast, the Summit SMBI24 is a standout for its simplicity and value. Its compact 1.2 cu. ft. size is smaller, but the included trim kit makes it a complete, easy-to-install solution for smaller kitchens, secondary prep areas, or 24-inch cabinet stacks.

For most people, the Frigidaire Gallery GMBS3068BF offers the best combination of premium features, a high-end design, and crucial installation flexibility with both 27″ and 30″ trim kit options. However, if your top priority is a simple, cost-effective, and DIY-friendly installation, the Summit SMBI24 is an unbeatable package.

Buyer’s Guide: How to Choose the Right Built-in Microwave

Choosing the right built-in microwave goes beyond just looks; it’s about ensuring a perfect fit and getting the features you’ll actually use. Use this guide to match your kitchen’s needs with the right appliance.

• Cabinet Dimensions & Trim Kit Sizing: This is the most critical factor. Before you do anything else, precisely measure your cabinet’s interior height, width, and depth. Most trim kits are designed for either 27-inch or 30-inch wide cabinets. You must check the microwave’s “required cutout dimensions” in the installation manual and ensure your space can accommodate it.
• Trim Kit: Included vs. Separate: A model with an included trim kit, like the Summit SMBI24, simplifies installation and guarantees a perfect color and fit match. Purchasing a separate trim kit, as required by the Frigidaire models, offers more flexibility but adds significant cost and the risk of ordering the wrong part. Always double-check that the trim kit model number is compatible with your chosen microwave.
• Capacity (Cubic Feet): Capacity is measured in cubic feet (cu. ft.). A compact model (around 1.2 cu. ft.) is fine for reheating plates and small tasks. A full-size model (1.8 to 2.2 cu. ft.) is necessary for large families, as it can accommodate bigger dishes and cook family-sized meals without issue.
• Cooking Technology (Sensor vs. Standard): Standard microwaves rely on you to set the time and power. Sensor cooking models use built-in humidity sensors to automatically adjust the cooking time for you. This feature is invaluable for preventing overcooking and is highly recommended if it fits your budget, as it produces noticeably better results.
• Wattage & Power: Wattage equals cooking speed. Most full-size microwaves are between 1000 and 1200 watts. A higher wattage will cook and reheat food faster and more evenly. I wouldn’t recommend going below 900 watts for a primary kitchen microwave.
• Ventilation is Non-Negotiable: This is a crucial safety consideration. Built-in microwaves are designed with specific ventilation requirements, usually venting out the front through the trim kit. Never, ever place a standard countertop microwave inside a closed cabinet without a proper trim kit, as it can overheat and become a serious fire hazard.
• Door Mechanism: Consider a push-button release versus a handle. Handles are often easier to grab, especially with full hands, and can feel more durable over time. Push-buttons offer a sleeker, more minimalist look that can blend better with flat-panel cabinets. This is largely a matter of personal preference and your kitchen’s style.

FAQs About Best Built in Microwave with Trim Kit

Do you need a trim kit for a built in microwave?

Yes, a trim kit is absolutely necessary for installing a microwave into a cabinet. It serves two critical purposes: it fills the unsightly gaps between the microwave and the cabinet for a seamless look, and most importantly, it provides the necessary ventilation channels to prevent the unit from overheating and becoming a fire hazard.

Are microwave trim kits interchangeable?

No, microwave trim kits are almost never interchangeable, even between models from the same brand. Each trim kit is specifically engineered for a particular set of microwave models to ensure a proper fit, secure mounting, and correct ventilation. Always buy the exact trim kit model recommended by the manufacturer for your specific microwave.

Can any microwave be built-in with a trim kit?

No, only specific models designated by the manufacturer as “built-in compatible” or “countertop with optional trim kit” can be safely installed in a cabinet. Standard countertop microwaves are not designed for the enclosed space and lack the proper front-venting design, creating a serious fire risk if you try to build them in.

Do built-in microwaves need ventilation?

Yes, all built-in microwaves require ventilation to operate safely. They are designed with internal fans that direct heat out and away from the electronic components. The trim kit is a key part of this system, as it has vents (usually on the top and bottom) that allow air to circulate properly.

What is the difference between a built-in and a countertop microwave?

A built-in microwave is designed to be installed flush within cabinetry using a matching trim kit, which handles ventilation and aesthetics. A countertop microwave is a standalone unit meant to sit on a counter and has its vents on the sides and back, which cannot be blocked.

How much space is needed for a built-in microwave?

The required space is determined by the “cutout dimensions” specified in the manufacturer’s installation manual. You must precisely measure your cabinet opening (height, width, depth) and ensure it meets or exceeds these minimum requirements for a successful and safe installation. Do not guess on this.

Why are trim kits so expensive?

Trim kits can seem expensive because they are more than just a simple cosmetic frame. They are engineered with specific ventilation passages, structural mounting brackets, and are manufactured in much smaller quantities than the microwaves themselves. This specialized design, low production volume, and the need for durable materials contribute to their higher cost.

How do you measure for a microwave trim kit?

You don’t measure for the trim kit itself; you measure your cabinet opening to match the microwave’s requirements. First, select the microwave you want. Then, find the “cutout dimensions” in its installation manual. Measure your cabinet’s interior width, height, and depth to ensure your space meets those required dimensions. The trim kit is then chosen based on the microwave model and the overall cabinet width (e.g., 30 inches).

Can you put a countertop microwave in a cabinet?

You should never put a standard countertop microwave in an enclosed cabinet or cubby. Countertop units vent from the sides and back. Enclosing them will block this critical airflow, leading to dangerous overheating and potential damage to the microwave, your cabinetry, and creating a fire risk.

What are the standard widths of a built-in microwave?

The microwave ovens themselves are typically around 24 inches wide. However, the trim kits are designed to make them fit into the two most common standard kitchen cabinet widths: 27 inches and 30 inches. It is crucial to buy the trim kit that matches your cabinet’s overall width.
