How we chose built-in convection microwaves
The best built-in convection microwave should fit the cabinet, provide the cooking modes you need and match the kitchen's electrical setup. We compared the stated dimensions, capacity, cooking functions and power requirements for these six options.
We gave the highest score to the KoolMore Reserve because it combines convection, air fry and microwave cooking with sensor cook and a stated temperature range. Other picks earn their place through broiling, multiple cooking modes, a hood and exhaust setup, or a compact trim format.
Our score weighs specs and features against what you're shopping for. Before buying, confirm the current installation instructions and the cabinet measurements for your exact model.

Best built-in convection microwaves by use
The KoolMore Reserve is the most versatile pick here, while the other models suit specific cooking needs and installation layouts. Each unit combines microwave heating with convection, but the additional modes and dimensions differ.
KoolMore Reserve Built-in Microwave Convection Oven: Best for air frying and convection
- 1.6 cu. ft. capacity
- Convection, air fry and microwave cooking
- 175°F to 450°F range
- 20-amp NEMA 5-20P plug
A 3-in-1 unit combines microwave, convection and air fry modes, with a stated temperature range from 175°F to 450°F. Plan for a compatible 20-amp outlet.
Pros
- Convection and air fry modes
- Sensor cook
- Soft-close door
Cons
- Requires a compatible 20-amp outlet
- Confirm cabinet fit using the full depth and height
The KoolMore Reserve is the most flexible choice in this group if you want microwave, convection and air fry modes in one appliance. Its 1.6 cu. ft. capacity is paired with sensor cook and a listed temperature range of 175°F to 450°F.
The convection fan supports baking and roasting, and the appliance also has a preheat function. Air fry is built in, so you can use one cabinet unit for several kinds of cooking.
Plan around its electrical requirement before planning the cabinet. KoolMore specifies a compatible 20-amp NEMA 5-20P outlet, and the appliance measures 24.42 in deep, 23.4 in wide and 17.87 in high.
Choose it if the air fry mode and wider temperature range fit your routine. Confirm the outlet, opening and clearances before installation.
KoolMore 24 Inch Built-in Oven and Microwave: Best for broiling and baking
- 1.5 cu. ft. capacity
- Convection and broil
- 1000-watt microwave power
- 20-amp NEMA 5-20P plug
Top and bottom heating with fan heaters supports convection cooking, while the broil function adds another cooking option. Its plug needs a compatible 20-amp outlet.
Pros
- Convection and broil modes
- Double-layer glass door
- Door hinges support up to 66 lb
Cons
- Requires a compatible 20-amp outlet
- Verify the cabinet opening and clearance
The KoolMore 24 Inch Built-in Oven and Microwave suits cooks who want convection and broil without an air fry mode. Its 1.5 cu. ft. cavity pairs microwave cooking with top and bottom heating and fan heaters.
The double-layered glass door is described as cool door technology. KoolMore also says the reinforced hinges can support up to 66 lb, which may help when moving hot cookware.
Its dimensions are 22.3 in deep, 23.4 in wide and 17.8 in high. Like the Reserve, it requires a compatible 20-amp NEMA 5-20P outlet, so check that connection before selecting the unit.
Pick this model if broiling and convection are the key extra functions. Compare its cabinet depth and height with the opening, and leave room for the drop-down door.
Sharp R1874T 30 in. 1.1 cu. ft.: Best for an over-the-range installation
- 1.1 cu. ft. capacity
- 850-watt microwave power
- Convection cooking
- Built-in exhaust and hood light
This convection microwave combines cooking with an exhaust system, hood light and fan. Its 30-inch class width makes it a different fit from 24-inch built-in models.
Pros
- Convection, bake, broil, crisp and roast functions
- Exhaust system with low and high fan settings
- Sensor settings
Cons
- Smaller 1.1 cu. ft. capacity
- Designed for an over-the-range location
The Sharp R1874T fits a different kitchen plan: it is an over-the-range convection microwave with an exhaust system. It has a 1.1 cu. ft. capacity, 850-watt microwave power and a 13-inch turntable.
Its convection functions include browning, baking, broiling, crisping and roasting. Sensor settings and an interactive display handle everyday microwave tasks, while the built-in fan and hood light add ventilation and cooktop lighting.
At 29.93 in wide, this model is much wider than the 24-inch built-in options. Check the cabinet and cooktop arrangement before choosing it, especially if you are replacing a standard over-the-range unit.
Choose Sharp when you need the ventilation and light along with convection cooking. If you only need a cabinet microwave and don't need a hood, compare the other picks first.
AAOBOSI 24 Inch Built in Microwave Oven: Best for air fry presets
- 1.6 cu. ft. capacity
- 10 cooking types
- Sensor cook and reheat
- 20-amp plug required
Its cooking modes include air fry, convection, broil and sensor options. The drop-down door needs room to open outward and downward.
Pros
- Air fry and convection modes
- 10 cooking types
- Includes baking tray and grill rack
Cons
- Requires a 20-amp plug
- Plan for the drop-down door's swing
The AAOBOSI 24 Inch Built in Microwave Oven gives you 10 cooking types in a 1.6 cu. ft. cavity. Its modes include air fry, broil, convection, sensor cook and sensor reheat, along with everyday options such as popcorn and pizza.
The touch controls include an auto menu with six preset programs. A halogen light lets you see inside while food heats, and the included baking tray and grill rack support its varied cooking modes.
The stated dimensions are 23.82 in wide, 22.26 in deep and 19.49 in high. Its door opens outward and downward, so check that the front space is clear and that your cabinet depth and height work.
Pick it if you want air fry presets and several microwave and oven modes. Confirm the required 20-amp connection as part of your installation plan.
AAOBOSI 24 Inch Built-in Microwave Convection Oven: Best for a broad set of cooking modes
- 1.6 cu. ft. capacity
- 12 cooking functions
- 11 microwave power levels
- 20-amp plug required
This AAOBOSI combines convection, air fry, broil and sensor cooking with 12 stated functions. Its recommended cabinet opening is 560+8 mm wide, 450+2 mm high and at least 550 mm deep.
Pros
- 12 cooking functions
- Includes turntable, ceramic tray and racks
- Recommended cabinet opening is specified
Cons
- Requires a 20-amp plug
- Check the opening measurements and door clearance
This AAOBOSI offers 12 cooking functions and 11 microwave power levels, including sensor cooking, air fry, broil and convection. The 1.6 cu. ft. cavity and multiple included trays and racks give it a broad range of stated uses.
Its recommended cabinet opening is 560+8 mm wide, 450+2 mm high and at least 550 mm deep. The appliance itself measures 23.4 in wide, 22.4 in deep and 17.9 in high, so use the installation measurements rather than relying on the 24-inch label.
It requires a 20-amp plug. The drop-down door also needs room in front of the cabinet, so check nearby counters and handles.
Choose this model if the specified cabinet opening matches your kitchen and you want multiple cooking modes. Confirm the outlet and door clearance before ordering.
RecPro 1.1 Cu. Ft. RV Black Convection: Best for compact cabinet installations
- 1.1 cu. ft. capacity
- Convection cooking
- Compact trim dimensions
- 120V / 10-amp requirement
A compact cabinet microwave with convection presets and express cooking options. Its trim and cutout dimensions matter for a planned built-in fit.
Pros
- Compact cabinet format
- Child lock
- Nine express cook options
Cons
- Smaller 1.1 cu. ft. capacity
- Check cutout and ventilation clearances
The RecPro 1.1 Cu. Ft.
RV Black Convection is the compact option for a cabinet opening that suits its trim dimensions. It has nine express cook options, a child lock and convection presets.
Without trim, the exterior measures 20.5 in wide, 14.75 in high and 18.5 in deep. The trim measures 23.9 in wide by 16.75 in high, while the stated cutout is 22.5 in wide, 15.1 in high and 19.25 in deep.
RecPro's described installation also calls for at least 1 in of clearance on all sides for ventilation. That means a small exterior footprint alone is not enough to confirm fit.
Pick it when those dimensions and clearances match your cabinet. Its 1.1 cu. ft. capacity is smaller than the 1.5 and 1.6 cu. ft. options above.
What should you check before buying a built-in convection microwave?
Check the cabinet opening, appliance depth, door swing and electrical requirement before comparing cooking features. A microwave can be labeled 24 in wide and still need a different opening or more front clearance than your kitchen allows.
Measure the opening at several points, then compare the manufacturer's installation dimensions. Include any trim kit, if used, and account for required ventilation space and nearby cabinet doors.
The door style affects how you use the appliance. A drop-down door needs clear space in front, while a model with a swing door needs side clearance and room to handle hot dishes.
For the electrical plan, check the exact plug and circuit needs. The KoolMore and AAOBOSI picks here call for a 20-amp connection, while the RecPro has a stated 10-amp requirement.
How much capacity do you need?
Capacity depends on the dishes you use and the number of portions you usually heat or cook. The picks here range from 1.1 cu. ft. to 1.6 cu. ft., so compare interior room with your largest regular dish.
A larger capacity can make it easier to fit bigger cookware, but it also takes up more cabinet space. If you mostly reheat plates and use small bakeware, a 1.1 cu. ft. model may be enough.
Think about cooking modes alongside capacity. A wider set of modes is useful only if you plan to use them and have the right accessories and clearances.
What does convection add to a built-in microwave?
Convection adds fan-assisted oven cooking to microwave heating, which lets a combination unit bake or roast as well as reheat. Some models also add broil or air fry modes, but those functions vary by appliance.
If you are comparing cabinet models with countertop designs, our best convection microwave countertop guide covers that alternative. A convection microwave drawer is another format to consider when cabinet placement and access matter.
A microwave and toaster oven combination may suit a different counter setup. See our best microwave toaster oven combo guide if you don't need a built-in unit.
Should you choose convection, broil or air fry?
Choose convection for fan-assisted oven cooking, broil for direct top heat and air fry when you want the appliance's dedicated air fry mode. Some models combine several of these features, while others focus on convection and broiling.
The KoolMore Reserve includes convection and air fry modes. The other KoolMore combines convection and broil, and both AAOBOSI models include air fry and broil among their stated functions.
A grill function is a separate feature to compare if browning is your priority. Our guide to the best microwave oven with grill explains that category.
For a vehicle installation, size and electrical needs can differ from a home kitchen. Compare the best convection microwave for RV options before choosing an RV model.
How do you clean a convection microwave?
Clean spills after the cavity cools, using a soft cloth and a cleaner that is suitable for the unit's interior surfaces. Check the manual for care directions before using a spray or abrasive pad.
Remove crumbs from racks and trays as they accumulate, and wipe the turntable and cavity without blocking vents. For product options, see our guide to the best microwave cleaner.
Which built-in convection microwave should you choose?
Choose the KoolMore Reserve if you want air fry, convection and sensor cooking in one 1.6 cu. ft. unit and can provide its required 20-amp outlet. Pick the other KoolMore for convection and broiling, or the Sharp if you also need an over-the-range exhaust system and hood light.
For a smaller cabinet plan, compare the RecPro's trim and cutout measurements with the opening. If you want 12 cooking functions and the specified opening fits, consider the second AAOBOSI.
Measure first, confirm the outlet, then choose the functions you will use most. That is the simplest way to narrow down the best built-in convection microwave for your kitchen.

Frequently asked questions
What is a built-in convection microwave?
A built-in convection microwave combines microwave heating with a fan-assisted oven mode and is designed for cabinet installation. Some models add broil or air fry functions.
Check the exact cabinet opening, depth, door swing and electrical requirements before choosing one.
Can a convection microwave replace a wall oven?
It can handle some oven tasks, such as baking or broiling, but capacity and cooking modes vary by model. These picks range from 1.1 to 1.6 cu. ft.
Compare the cavity size and modes with the dishes you cook most often before treating one as your only oven.
Do built-in convection microwaves need a special outlet?
Some do. The KoolMore models here require a compatible 20-amp NEMA 5-20P outlet, and both AAOBOSI models specify a 20-amp connection.
Check the exact model's electrical needs and have the kitchen circuit assessed before installation.
How do I check if a built-in microwave will fit?
Measure the cabinet opening's width, height and depth, then compare them with the appliance dimensions and its installation instructions. Also account for ventilation and the door's full swing.
A 24-inch label alone does not confirm that the cabinet opening or depth will work.
