Customer Reviews
Customer Review: “I bought this to replace a ge built in microwave that we have had for 12 years. ge no longer make a built in microwave. All built ins (as opposed to over the range) are counter top microwaves with a facia plate including a vent system that attaches to the front of the cabinet, this one is the same.The difference with this is that the fascia is included in the price, the others were extra and cost nearly as much as the microwave itself.It came very well packaged and was delivered via UPS, the assembly was easy and the instructions were clear and concise, we had the old one out and the new one installed in about an hour. Everything was strong and robust, all of the holes lined up exactly as they should and the finished installation looked great.”
– Customer Name: Robert M.
Customer Review: “We really like the new microwave and trim kit. The installation was straightforward, instructions were clear, the unit works well and is powerful, has all the features we desired. Our old unit just died and lasted a long time, so this newer unit has more functionality compared to it. Still getting used to it and have not tried all the functions yet, but so far we are happy with the unit. I would have given it 5 stars, but the cost for this microwave/trim kit is just so high (as they all are in the same class). Sign of the times and tariff impact.”

Customer Reviews
Customer Review: “I like the GE Convection Microwave Oven, 1050W. I have used the microwave, the air fryer, the convection oven and all work great. My old microwave was higher wattage, but I have not had to add much extra time to heat things up. The beeping is a bit annoying, but I’m getting used to it. It tells you when it’s HOT, which is a good safety feature. A lot of smudges on the stainless steel parts, but that’s expected. It fits in the standard microwave spot in my cabinets above my kitchen counter.”
– Customer Name: Jennifer W.
Customer Review: “It really is so different than a microwave. The ability to heat food up in the air fry mode is so much better than turning my gas oven. And then be able to microwave. It took a little to get used to the controls but now it’s fine. A little odd that the main microwave button ‘Cook time’ is in a random spot rather than at the top or highlight it somehow. Wish companies used white type on black rather than the light grey (I ain’t getting any younger!). It is also a bit underpowered but not a big deal. The most annoying this this thing beeps soooo loud! So loud. I contacted GE to see if the volume could be turned down and they said no. It’s loud like something extremely dangerous is happening with the oven. Lol. Overall much better than a regular microwave.”

Complete Buying Guide for 27 Inch Built In Microwave Convection Oven
Essential Factors We Consider
When evaluating 27 inch built in microwave convection ovens, we examine several critical factors that determine overall performance and user satisfaction. Capacity is paramount—consider your household size and cooking habits. Look for models with at least 1.5 cu. ft. for families and 1.0 cu. ft. for smaller households. Power output (measured in watts) directly affects cooking speed and efficiency; 1000W or higher generally delivers superior results. Advanced features like sensor cooking, multiple power levels, and programmable presets significantly enhance usability and food quality.
Budget Planning
Your budget should reflect your cooking needs and kitchen priorities. Entry-level models typically range from $150-$250 and offer basic microwave and convection functions. Mid-range options ($250-$500) include enhanced features like air frying, smart connectivity, and better build quality. Premium models ($500+) provide commercial-grade performance, extensive cooking functions, and professional installation packages. Remember to factor in installation costs, especially for built-in units requiring cabinet modifications.
Final Thoughts
The best 27 inch built in microwave convection oven for you depends on your specific kitchen needs, cooking preferences, and budget constraints. Whether you prioritize maximum capacity, advanced smart features, or ergonomic design, today’s market offers exceptional choices across all price points. Consider your daily cooking patterns, available space, and desired functionality before making your decision. With proper research and consideration of our detailed reviews, you’ll find the perfect appliance to transform your kitchen experience.
Frequently Asked Questions
Q: What is the difference between a microwave convection oven and a regular microwave?
A: The primary difference lies in cooking technology. Regular microwaves use electromagnetic waves to agitate water molecules in food, providing rapid heating. Microwave convection ovens add a convection fan and heating element, circulating hot air to create crisp exteriors and browning—similar to conventional ovens. This combination allows for faster cooking times while achieving better texture and appearance on foods.
Q: How much space do I need for a 27 inch built-in microwave convection oven?
A: A 27-inch microwave requires specific cabinet dimensions for proper installation. Standard cutout specifications are typically 17 1/8″ H x 25 1/2″ W x 22 3/4″ D. Ensure your cabinetry has adequate ventilation space (at least 2 inches on sides and back) and electrical access. Some models come with trim kits that cover gaps between the appliance and cabinetry, creating a seamless appearance.
Q: Are built-in microwave convection ovens more expensive than countertop models?
A: Generally, yes. Built-in models typically cost 20-40% more than comparable countertop versions due to their permanent installation features, enhanced construction, and professional appearance. However, they often include trim kits and installation hardware that countertop models lack. Consider the long-term value and kitchen integration benefits when comparing prices.
Q: How do I maintain my microwave convection oven for optimal performance?
A: Regular maintenance ensures longevity and peak performance. Clean the interior weekly with mild soap and water, paying special attention to the door seal and turntable. Use a microwave-safe cleaner for stubborn stains. Allow the appliance to cool completely before cleaning. Periodically check and clean ventilation grates. Follow manufacturer guidelines for descaling (if applicable) and never operate the unit empty.
Q: Can I install a microwave convection oven above my stove?
A: While possible, installing a microwave above a stove requires careful consideration of safety and functionality. Ensure proper ventilation, electrical supply, and structural support. Maintain at least 30 inches of clearance between the microwave and stove hood to prevent heat transfer issues. Professional installation is strongly recommended for overhead placements.
In conclusion, finding the perfect 27 inch built in microwave convection oven involves balancing your specific cooking needs, kitchen space, and budget considerations. Each model we’ve reviewed offers unique advantages, from the premium Café unit’s smart connectivity to the BLACK+DECKER’s budget-friendly versatility. Consider how you’ll use your microwave most frequently—whether for quick reheating, elaborate meal preparation, or entertaining guests—and choose accordingly. Remember that investing in quality pays dividends through improved cooking results, enhanced kitchen aesthetics, and reliable performance for years to come. Explore our detailed reviews above to find the model that perfectly aligns with your lifestyle and culinary aspirations.
