8 Best 400 CFM Over the Range Microwaves for Venting (2026)

In October 2026, I compared 8 best 400 CFM over the range microwaves from BLACK+DECKER, GASLAND, Midea and more, weighing vent fan speed, cavity size, and cooktop lighting. The BLACK+DECKER Over the Range Microwave Oven takes the top spot, with the Midea 1.7 cu. ft. as the budget pick.

Published Oct 27, 2026 Updated Oct 28, 2026 4 min read

A wall of over-the-range microwaves looks identical in product photos: stainless box, black glass, a row of buttons. What separates them sits underneath, in the exhaust fan that has to do the job your range hood used to do. A 400 CFM rating is the middle ground most 30-inch units in this group share, and it is enough airflow for regular searing, boiling, and sheet-pan roasting without the roar of a dedicated high-output hood.

I compared 8 units on the details that decide daily use: stated vent airflow, cavity size, whether the fan runs at one speed or two, and how the keypad sits for someone holding a hot pan. Each pick earns a BHK Score from those specs rather than from a stovetop session.

My overall pick for best 400 CFM over the range microwaves is the BLACK+DECKER Over the Range Microwave Oven. The two-speed fan lets you leave it on low through a simmer and switch to high the moment a pan starts smoking, and the turntable can be switched off so a rectangular baking dish sits flat instead of fighting the rotation. My top picks are just below.

A Note on Ratings. Manufacturer specs aren't always independently verified, so results can vary with how a product is used and cared for. Every pick is compared on its stated specs, materials, and verified owner feedback before it makes this list. Still, check the manual and the current listing before you buy, especially for temperature limits, cooktop compatibility, and care instructions.

BLACK+DECKER Over the Range Microwave Oven

BLACK+DECKER
9.9 BHK Score
Excellent

This BLACK+DECKER over-the-range microwave offers 1000 watts and a 1.9 cubic foot capacity for typical household cooking needs.

Key Facts

Capacity
1.9 Cu.Ft
Power
1000 Watts
Venting Fan
Two-speed 400 CFM
Dimensions
29.9 x 16.4 x 13.9 inches

Pros

  • +1000 watts with ten power levels for precise cooking control
  • +1.9 cu.ft capacity balances space and cooking volume
  • +Two-speed venting fan with 400 CFM clears common kitchen fumes
  • +Cooktop LED lighting enhances stove top visibility

Cons

  • −Bulky dimensions may challenge installation in smaller kitchen spaces
  • −Limited color option restricts style matching to stainless steel kitchens
  • −Turntable diameter limits some extra-large dishware compatibility

Detailed Review

This BLACK+DECKER microwave features a 1.9 cubic foot capacity paired with 1000 watts of power and ten power levels which support a range of cooking tasks from reheating to defrosting. I see the two-speed 400-CFM venting fan as useful for kitchens needing moderate ventilation without a separate hood. The LED cooktop lighting is a practical addition that improves stove visibility during cooking. Worth knowing before you buy is the unit’s size of nearly 30 inches wide and over 16 inches tall which requires sufficient over-the-range clearance. I’d consider this model for households wanting a multi-function microwave with venting and lighting integrated but with enough space to accommodate typical dinnerware. The turntable on/off feature adds flexibility but may limit use with very large dishes.

9.9 BHK Score
Excellent

TOSHIBA’s over-the-range microwave offers 1.9 cu.ft capacity and 1000W power for family-size meal prep.

Key Facts

Capacity
1.9 Cu.Ft
Power Output
1000 Watts
External Dimensions
29.9 x 13.8 x 16.4 Inches (WxDxH)
Weight
54.7 Pounds

Pros

  • +Hydraulic damper enables quiet, gentle door closing
  • +Sensor cooking adjusts power using food moisture detection
  • +Two-speed 400 CFM fan handles ventilation needs
  • +Redesigned flip and lock bracket simplifies installation

Cons

  • −Depth of 13.8 inches may limit fit in tight spaces
  • −Weight near 55 pounds requires sturdy mounting support
  • −No dishwasher-safe parts specified for easier cleanup

Detailed Review

This TOSHIBA microwave features a 1.9 cu.ft capacity with a 13.5-inch turntable, suitable for warming several plates at once, which fits well for family-sized meal prep. The soft-close door uses a hydraulic damper to prevent slamming and reduce wear over time, adding convenience in a busy kitchen. Its 400 CFM two-speed exhaust fan provides ventilation strong enough for open-concept kitchens to clear cooking odors and steam.

Installation benefits from a redesigned flip and lock bracket aimed to shorten setup time, though the unit’s 13.8-inch depth requires checking for proper clearance above the stove. I see this microwave working best for households needing a mid-sized capacity and reliable ventilation without elaborate features. Worth knowing before buying is the lack of dishwasher-safe components, so cleaning will be manual.

9.8 BHK Score
Excellent

Midea’s over-the-range microwave offers 1.2 cu.ft capacity and 1000W power with a slim stainless steel body.

Key Facts

Capacity
1.2 Cu.Ft
Power
1000W
Vent Fan
400 CFM
Color
Stainless Steel

Pros

  • +Slim low profile saves cabinet space
  • +Sensor cook technology adjusts time for better results
  • +SmartHome compatibility enables remote control and monitoring

Cons

  • −Dimensions require sufficient overhead clearance, not for very low cabinets
  • −Limited color option only in stainless steel finish

Detailed Review

This Midea microwave stands out with its 1.2 cubic feet capacity and 1000W power, making it a practical choice for typical family cooking. Its slim stainless steel design is intended to free up overhead cabinet space, which is helpful in kitchens where maximizing room above the stove matters. The 400 CFM vent fan offers ventilation to reduce cooking odors and smoke, an important feature for over-the-range models.

I see this microwave working best in kitchens that can accommodate its specific dimensions of 18.2 by 29.9 by 10.3 inches, so low or shallow cabinets might pose an installation challenge. The voice control and SmartHome app integration allow for remote cooking and vent control, which adds convenience but requires compatible devices.

Worth knowing before you buy is the single finish option of stainless steel, which might limit aesthetic matching. For my money, this model suits households looking for a mid-capacity microwave with smart features and space-conscious design.

9.7 BHK Score
Excellent

Key Facts

Capacity

Power
1000W
Rating
UL Certified
Included
Glass turntable, removable rack, grease filters, mounting accessories

Pros

  • +Multiple cooking power levels including 2-stage automatic cooking
  • +Large interior capacity suitable for family-sized meals
  • +Quiet, powerful ventilation fan with two speeds
  • +Included accessories support installation and operation

Cons

  • −Relatively bulky size may challenge smaller kitchen spaces

Detailed Review

The GASLAND 30 Inch Over the Range Microwave features a 1.9 cubic feet interior allowing it to accommodate larger cookware such as 12-inch pizzas and casseroles. It delivers 1000 watts of cooking power with 11 power levels, including a 2-stage cooking function that adjusts power automatically during a cycle for better cooking results. The microwave includes a 400 CFM two-speed exhaust fan designed to remove kitchen smoke and odors and operates more quietly than many comparable models. I'd consider this microwave for kitchens needing a balance of strong ventilation and cooking capacity.

Installation fits standard 30-inch over-the-range spaces and comes with a removable rack and turntable on/off function, adding flexibility for larger dishes. Worth knowing before you buy is the microwave's dimensions which may be bulky for smaller kitchens and it only comes in silver, limiting aesthetic options.

Detailed Review

The GE Profile 30" Over-the-Range Microwave features a 1.2 cu. ft. capacity which fits mid-sized cooking tasks but may feel small for larger families. It delivers 1000 watts which balances power and energy use for typical reheating and cooking.

This model's 400 CFM two-speed venting system improves kitchen air quality by efficiently removing smoke and odors, a useful feature over standard microwaves. The low profile design saves valuable countertop space, making it suitable for smaller kitchens.

I see this microwave working best for cooks who want integrated venting and lighting with sensor cooking controls. Worth knowing before purchase is the stainless steel surface requires upkeep to maintain its appearance and there are no dishwasher-safe components listed for cleaning convenience.

9.5 BHK Score

Detailed Review

This GASLAND 30-inch over-the-range microwave offers a 1.9 cubic foot capacity which accommodates larger dishes, making it suitable for family-sized meals. The unit runs at 1000 watts with 11 power levels, allowing for more precise cooking control including gentle defrosting and stronger heating phases.

The integrated 400 CFM ventilation fan helps clear cooking odors and smoke efficiently, while two LED lights illuminate the stovetop for better visibility. I see this microwave working best in kitchens where counter space is limited but overhead space allows for its larger footprint.

Worth knowing before purchase is the product’s relatively large size and the lack of detailed material or coating information, which may concern those prioritizing specific interior finishes. Overall, I rate this a reasonable pick for households needing capacity and ventilation combined.

Detailed Review

This ThermoMate over-the-range microwave offers a 1.9 cubic foot capacity, which is sizeable enough to handle multiple dishes or larger meals simultaneously thanks to the included removable rack. Its 1000 watts of power across 11 levels provide flexibility for precise cooking needs, supported by sensor cooking that adjusts timing and power for optimal results. The microwave also integrates a 400 CFM ventilation system with two fan speeds designed to clear smoke, steam, and odors while cooking. The built-in LED lighting enhances visibility over the cooktop, a practical addition for monitoring food.

Worth knowing before you buy is that the microwave’s footprint is somewhat large, measuring nearly 30 inches wide and over 15 inches deep, which might challenge installation in kitchens with limited space. The stainless steel finish is the only color option, offering a modern look but little variety. I see this model working best in kitchens where ventilation and capacity matter most, especially for households needing to cook multiple items at once.

9.4 BHK Score

Detailed Review

This Midea over-the-range microwave features a 1.7 cu.ft capacity with a 12.4-inch turntable, which is large enough for items like a rotisserie chicken or 12-inch pizza. Its 1000W power output and 10 power levels allow for tailored cooking settings to meet various heating needs. The built-in 300 CFM ventilation system with adjustable fan speeds is designed to clear cooking odors effectively while the bright cooktop light helps monitor your food without opening the door. I see this microwave working best in kitchens where space is limited but a larger interior is still needed. Worth knowing before you buy is its weight of 52 pounds, which means installation should be done carefully to ensure proper support.

FAQs

What does 400 CFM mean on an over-the-range microwave?

It is the volume of air the exhaust fan moves on its highest setting, measured in cubic feet per minute. A 400 CFM fan clears everyday steam and light smoke from a 30-inch cooktop without the noise of a dedicated high-output hood. Grease filters still need regular washing for the fan to keep pulling air.

Do you need a 400 CFM microwave if you already have a hood?

An over-the-range microwave replaces the hood rather than supplementing it, so the fan rating becomes your only ventilation. Where an existing hood vents outdoors and works well, swapping it for a microwave trades hood performance for counter space. Confirm the duct path and cabinet opening before ordering.

Does the cooktop below change how much venting you need?

A 400 CFM fan handles most electric and mid-output gas burners for boiling and searing. High-BTU wok burners and long griddle sessions produce more smoke than that rating clears, so run the fan on high and crack a window. If the range itself is undecided, this comparison of induction ranges covers the other half of the equation, since the cooktop below decides how much steam the fan has to move.

Can a low-profile microwave still vent 400 CFM?

Slim bodies can reach the same airflow rating as full-size units, so ventilation is rarely the compromise. The trade is cavity capacity, since a low-profile unit fits under short cabinets but holds less, which may mean switching off the turntable or using a smaller dish. Clearance above the cooktop should follow the manual.

Final Thoughts

Vent capacity and cavity size are the two things you cannot fix after installation, so start there. Controls, lighting, and preset menus are conveniences you adapt to within a week; a fan that cannot keep up with your cooking, or a cavity too small for your baking dish, stays irritating for years.

For most kitchens the BLACK+DECKER Over the Range Microwave Oven is the safest call. It pairs the two-speed 400 CFM exhaust with a full-size cavity, and the turntable-off setting means a rectangular pan fits without forcing the rotation. Add cooktop LED lighting and one-touch menus and you have a unit built for weeknight reheating and weekend batch cooking alike.

If the budget sets the ceiling, the Midea Over the Range Microwave Oven, 1.7 Cu.Ft is the pick. It covers the basics: a 1.7 cu. ft. cavity that takes a 12-inch pizza, 18 auto menus, and 10 power levels. Its fan is rated below the 400 CFM headline, though, so it suits light everyday cooking better than heavy searing. Where cabinets sit low over the range, the GE Profile 30″ Over-the-Range Low Profile is built for that gap. Getting the vent rating and cavity size right is what removes the guesswork; the rest is preference.
