If you specifically need a 27-inch stainless steel wall oven and microwave combo, the Frigidaire Gallery is the only product in this group listed at that width. The other options are 24-inch compact models or a 30-inch unit, so they may not fit your cabinet opening. Before choosing, compare the appliance’s installation manual with your cabinet dimensions and electrical setup—not just the width in the product title.

Our Picks: Best 27 Inch Wall Oven Microwave Combo Stainless Steel reviews
1. Frigidaire Gallery 27-Inch Combo: Closest Match to the Target Size
The Frigidaire Gallery is the most direct fit for this roundup: its title identifies it as a 27-inch electric built-in wall oven and microwave combination. The listing describes a stainless steel finish, Total Convection, and a 5.5-cubic-foot capacity. That larger stated capacity sets it apart from the compact 24-inch options here.
It is a substantial appliance, listed for 240-volt power and a 4,000-watt rating. Those requirements make electrical compatibility and professional installation important parts of the purchase decision. The supplied product dimensions appear inconsistent with the stated 27-inch width, so use Frigidaire’s installation documentation to confirm the unit’s exact cutout and exterior measurements before ordering.
The main caution is the limited ownership information available. One reported experience describes the oven shutting down early in ownership and a lengthy repair process. A single account does not establish a general reliability pattern, but it is a reason to check the warranty terms, service coverage in your area, and return options before committing.
Pros:
- Listed as a 27-inch wall oven and microwave combination
- Total Convection and stainless steel finish
- 5.5-cubic-foot capacity listed
- Electric built-in design for a coordinated kitchen installation
Cons:
- Requires a compatible 240-volt electrical connection
- Confirm exact cabinet dimensions and service support before purchase
Verdict: Choose this Frigidaire first if you need a 27-inch combination unit, but verify its installation specifications and local service options before buying.
2. KoolMore 24-Inch Combo: Compact Convection and Broiling
The KoolMore is a compact 24-inch built-in combination appliance, not a 27-inch model. Its listed 1.5-cubic-foot capacity and mix of microwave, convection, and broil functions make it a space-saving option for kitchens where a full-size oven is not essential or is already available.
The listing highlights a double-layered glass door, touch controls, and 14 cooking programs. Its electrical setup needs special attention: it is specified for 120 volts and a 20-amp NEMA 5-20P outlet. Check the receptacle and circuit requirements before purchasing; a standard outlet may not be suitable. The unit’s smaller capacity is also a clear trade-off compared with the Frigidaire Gallery.
This model makes the most sense when a 24-inch opening is already in place and you want microwave convenience plus convection and broiling in one appliance. It should not be treated as a drop-in replacement for a 27-inch appliance without confirming the cabinet and installation requirements.
Pros:
- Combines microwave, convection, and broil functions
- Compact built-in format with a listed 1.5-cubic-foot capacity
- Touch controls and multiple cooking programs
- Double-layered glass door design
Cons:
- 24-inch width does not match a 27-inch opening without cabinet changes
- Requires a compatible 20-amp NEMA 5-20P outlet
Verdict: Consider the KoolMore if your kitchen is designed for a 24-inch unit and its outlet requirements are already met; skip it if you need an exact 27-inch replacement.
3. Frigidaire Professional 30-Inch Combo: More Room and Air Fry
This Frigidaire Professional is a 30-inch electric wall oven and microwave combination. It is wider than the target size, but it may suit a kitchen with a 30-inch cabinet opening and a need for more cooking space. The listing gives it a 7-cubic-foot capacity and calls out Total Convection and Air Fry.
The unit is listed for 240-volt power at 4,000 watts, so installation planning matters. Its product data also includes dimensions that appear unusually large for a built-in appliance. Confirm the manufacturer’s installation guide for the true cabinet cutout, required clearances, and exterior dimensions rather than relying on the supplied listing measurements.
Compared with the 27-inch Gallery, this model offers a larger stated capacity and an Air Fry feature, but it requires a wider opening. It is not a practical choice for a 27-inch cabinet unless you are prepared to change the cabinetry and confirm the installation details.
Pros:
- 7-cubic-foot capacity listed
- Total Convection and Air Fry features
- Stainless steel built-in design
- Electric 240-volt configuration
Cons:
- 30-inch width is not a direct fit for a 27-inch opening
- Exact installation dimensions should be confirmed with the manufacturer
Verdict: Pick this model only if your cabinet is built for a 30-inch unit and you value the larger stated capacity and Air Fry mode over a 27-inch fit.
4. GASLAND 24-Inch Built-In Microwave: Sensor Cooking in a Compact Size
The GASLAND is listed as a 24-inch built-in microwave with a 1.6-cubic-foot capacity, 1,000-watt microwave output, and 120-volt power. Its product description also promotes convection and broiling functions, along with sensor cooking, auto defrost, and preset programs. Because the listing title emphasizes a microwave rather than a full-size wall oven, treat it as a compact alternative—not a direct equivalent to the 27-inch Frigidaire.
The stainless steel finish and touch controls suit a built-in kitchen setup. The description mentions a multi-layer glass door and a soft-close feature, but shoppers should confirm the exact door operation and installation requirements with the manufacturer. At 24 inches wide, it will not directly fill a 27-inch cabinet opening.
This option may work for someone who wants a built-in microwave with extra cooking modes and a compact footprint. If you need a full-capacity wall oven beneath or above a microwave, compare the installation design and cooking capacity carefully; the listed 1.6-cubic-foot interior is much smaller than the Frigidaire Gallery’s stated oven capacity.
Pros:
- 1.6-cubic-foot capacity and 1,000-watt microwave output listed
- Sensor cooking, auto defrost, convection, and broil functions described
- Stainless steel finish with touch controls
- 120-volt power specification
Cons:
- 24-inch format is not a direct match for a 27-inch cabinet
- Its built-in microwave format may not replace a full-size wall oven combo
Verdict: Choose the GASLAND for a compact built-in microwave with additional cooking modes, not when a 27-inch full-size oven and microwave combination is essential.
5. ThermoMate 24-Inch Combo: Several Cooking Modes for Smaller Kitchens
The ThermoMate is a 24-inch built-in microwave and convection oven combination with a listed 1.6-cubic-foot capacity. Its described modes include microwave cooking, convection, broil, sensor cooking, reheating, defrosting, and rapid preheating. The product data lists 120-volt power, 1,000-watt microwave output, a 1,700-watt convection element, and a 1,750-watt broil element.
The included ceramic turntable and wire rack offer different ways to position food for microwave or convection use. However, the listing’s several wattage figures describe different functions, so check the installation guide for the appliance’s electrical requirements. The listed width is 24 inches, making this a compact alternative rather than a direct 27-inch replacement.
Some owners describe strong cooking results and helpful service, while one account raises a concern about metal contact and sparking around the turntable after extended use. That experience does not show how common the issue is, but it is worth following the manual’s instructions for rack and turntable placement and contacting the manufacturer if the turntable becomes damaged or begins to spark.
Pros:
- Multiple cooking modes, including microwave, convection, and broil
- 1.6-cubic-foot capacity listed
- Includes a ceramic turntable and wire rack
- Stainless steel finish with touch controls
Cons:
- 24-inch width will not directly fit a 27-inch opening
- A reported turntable concern makes careful setup and use important
Verdict: The ThermoMate is worth considering for a 24-inch space if you want several cooking modes, but check its installation instructions and handle the turntable and rack as directed.
How to Choose a 27-Inch Wall Oven Microwave Combo
Measure the Cabinet Opening, Not Just the Appliance Width
A product labeled 27 inches may not have a 27-inch exterior width, and the cabinet cutout is a separate measurement. Check the installation guide for the required opening width, height, depth, clearances, and trim dimensions. Also measure the path into your kitchen, including doorways and turns, so the appliance can reach its final location.
Match the Appliance to Your Electrical Setup
The 27-inch Frigidaire Gallery and 30-inch Frigidaire Professional are listed as 240-volt models. The 24-inch KoolMore, GASLAND, and ThermoMate products are listed for 120 volts, though the KoolMore calls for a specific 20-amp NEMA 5-20P outlet. Confirm the circuit and receptacle requirements in the manufacturer’s instructions and consult a qualified electrician if you are unsure.
Decide How Much Oven Capacity You Need
Capacity affects the size of dishes you can cook and how much food you can prepare at once. The Frigidaire Gallery is listed at 5.5 cubic feet, and the 30-inch Professional at 7 cubic feet. The compact 24-inch models list capacities around 1.5 to 1.6 cubic feet, so consider whether they can handle your usual pans and meals before treating one as a replacement for a full-size wall oven.
Compare the Cooking Modes You Will Actually Use
Convection circulates heated air, while broil adds a high-heat cooking option. The Frigidaire Professional is the only product here whose title calls out Air Fry. The compact models add features such as sensor cooking, preset programs, or a turntable and rack. Focus on the modes that match your routine rather than choosing solely by the length of the feature list.
Check the Installation Style and Included Components
These products are described as built-in or wall-mounted appliances, but their formats and included parts differ. Read the manual to confirm the required cabinet design, mounting method, ventilation space, and any included rack or turntable. Do not assume that a 24-inch microwave-style unit can replace a stacked wall oven and microwave without changes to the cabinet.
Consider Finish, Cleaning, and Daily Access
Stainless steel gives these appliances a coordinated look, but the supplied details do not describe every model’s smudge resistance or cleaning needs. Check the care instructions and consider how the door opens in your kitchen. A clear view of the interior, easy-to-reach controls, and a door that suits your cabinet layout can make everyday use more comfortable.
Review Warranty and Local Service Options
The Frigidaire listings specify a one-year manufacturer warranty. For other models, check the product page and manufacturer documentation for warranty coverage. Before ordering a large built-in appliance, find out who handles installation and repairs in your area, and understand the return process if the unit arrives damaged or does not fit.
Frequently Asked Questions
Which option here is actually listed as 27 inches wide?
The Frigidaire Gallery electric built-in wall oven and microwave combination is the only product in this group listed as 27 inches. The KoolMore, GASLAND, and ThermoMate models are 24 inches, while the Frigidaire Professional is 30 inches.
Can I put a 24-inch combo in a 27-inch cabinet opening?
Do not assume it will fit securely or look finished. Built-in appliances require specific cutout dimensions and clearances. Check the manufacturer’s installation guide and ask a qualified installer whether your cabinet can safely accommodate the unit.
Are all five products full-size wall oven and microwave combinations?
No. The Frigidaire Gallery and Frigidaire Professional are described as wall oven and microwave combinations. The KoolMore and ThermoMate are compact 24-inch oven-and-microwave combinations, while the GASLAND is titled as a built-in microwave with additional cooking functions. Compare capacity and installation details before treating them as interchangeable.
What electrical connection does the 27-inch Frigidaire Gallery require?
The supplied product information lists the Gallery at 240 volts and 4,000 watts. Confirm the circuit requirements in the manufacturer’s installation documentation before purchase and have electrical work completed by a qualified professional.
Which model has the largest listed capacity?
The 30-inch Frigidaire Professional has the largest listed capacity at 7 cubic feet. The Frigidaire Gallery is listed at 5.5 cubic feet. The smaller 24-inch models have capacities around 1.5 to 1.6 cubic feet.
Does the 27-inch Frigidaire include Air Fry?
Air Fry is called out in the title for the 30-inch Frigidaire Professional. The supplied information for the 27-inch Frigidaire Gallery highlights Total Convection but does not list Air Fry as a feature.
Final Recommendation
For a stainless steel wall oven and microwave combo that matches a 27-inch search, the Frigidaire Gallery is the clearest fit in this selection. Its listed 5.5-cubic-foot capacity and Total Convection stand out, but confirm the cutout dimensions, 240-volt electrical requirements, and service coverage before ordering. If your cabinet opening is actually 24 or 30 inches, consider the appropriately sized alternatives—but do not choose one based on width alone.
