Best Large Low Profile Microwave: GE Profile Wins

The best large low profile microwave is the GE Profile UVM9125DYWW, a 30-inch, 1.2 cu ft over-the-range unit that pairs a 1000-watt cavity with a 400 CFM two-speed vent in a body just 10.3 inches tall. The Samsung ME11A7710DS/AA is the pick for a busier cooktop, because its 550 CFM hood pulls harder than any other slim here and adds Wi-Fi and voice control on top. The trade-off is a slightly smaller 1.1 cu ft interior in exchange for stronger ventilation.

Best large low profile microwave at a glance

What buyers get wrong about low profile microwaves

Most shoppers compare wattage first. That is not what decides this category. Every full-size pick in this set is rated at 1000 watts, and the Samsung's 1100 watts does not translate into meaningfully faster reheats. The specification that actually splits this field is the trio of external height, vent CFM and cavity volume, and the tension between them is what makes a large low profile microwave hard to shop for.

Height is the whole point of the category. A traditional over-the-range unit stands roughly 16 to 17 inches tall, which crowds a cook working at the front burners. Every 30-inch pick here comes in at 10.3 to 10.8 inches. That reclaimed six inches is space you feel every time you lift a stockpot lid.

The compromise is the interior. To lose the height, manufacturers have to shrink the cavity. Five of the seven picks land at 1.2 cu ft, the Samsung at 1.1 cu ft, and only the smaller-footprint KoolMore stretches to 1.3 cu ft by giving up the 30-inch width. If you regularly reheat rectangular casserole dishes or a full dinner plate with a bowl on it, verify the interior width against the widest platter you own before you commit.

1. GE Profile UVM9125DYWW — Best overall

A 1.2 cu ft slim in white with a 400 CFM two-speed vent and bottom-mounted controls, and the strongest all-round data sheet in this set.

Best for: a 30-inch range wall where countertop room matters more than a wide feature list Skip it if: your kitchen is finished in stainless and a white body would clash

At 10.3 inches tall by 29.9 inches wide by 18.6 inches deep and 51 lb, this GE Profile matches the standard undercabinet hood footprint most 30-inch ranges are designed around. That is what "low profile" is supposed to mean, and this listing spells it out. The 1.2 cu ft cavity and 1000-watt output are the median of this set, and the 400 CFM two-speed vent is what four of the six 30-inch picks quote. GE says the hood is a two-speed system and that sensor cooking adjusts time and power automatically. Warranty coverage is a limited one-year on the entire appliance, which is standard for the set.

What earns this the top slot is not any single spec but that the whole data sheet is filled in: dimensions, weight, warranty terms and model number are all present. Several rivals leave gaps. The trade-off is the finish. If you need stainless, the identical UVM9125STSS is the same appliance in a different skin.

Pros:

• Full dimensions and 51 lb weight both published
• 400 CFM two-speed vent
• Integrated bottom handle with bottom controls
• 10.3 in body fits a standard undercabinet slot
• Complete one-year appliance warranty stated

Cons:

• White limits kitchen match options
• Only two sellers list it
• Priced at the higher end of this set

2. Midea MMO12S3ASTZ — Best for heavy use

A 2024-released 1.2 cu ft stainless slim with SmartHome app control at an entry price position.

Best for: cooks who reheat and defrost every day and want app control at an entry price Skip it if: you refuse to link a kitchen appliance to Wi-Fi

The Midea is the second-cheapest of the seven and the newest model here, released in 2024. Dimensions come in at 10.3 x 18.2 x 29.9 inches, so it drops into the same 30-inch slot as the GE Profile pair. Midea says the cavity is 1.2 cu ft with 1000 watts of heating and a 400 CFM vent fan, and that the SmartHome app handles remote start, notifications and voice control. A steam-sensing reheat is claimed to set time and power without input.

For daily heavy use the app matters. If you reheat coffee at 07:00, defrost chicken at 15:30 and steam broccoli at 18:00, being able to tap "reheat" from another room is a real workflow gain. This pick also sells faster than four of the seven, which suggests the price-to-feature match is landing. The trade-off is the data sheet: no shipping weight is published, and the colour field is written as a marketing sentence rather than a clean value. Everything the specifications do state matches the GE Profile pair, though.

Pros:

• Entry-tier price for a 1.2 cu ft slim
• Wi-Fi and voice control via SmartHome
• 2024 model with steam-sensor reheat
• 400 CFM vent claim matches the GE Profile
• Sells faster than most of this set

Cons:

• No published weight
• Colour field reads as ad copy
• Requires a Wi-Fi setup to unlock its main advantage

3. GE Profile UVM9125STSS — Best for families

The stainless twin of the overall winner, same 1.2 cu ft cavity, same 400 CFM two-speed vent, same 51 lb body.

Best for: families running a stainless kitchen who want the GE Profile build in the matching finish Skip it if: you would rather pay less for the same specifications in white

This is the UVM9125DYWW in stainless steel, and every specification in the listing lines up: 10.3 x 18.6 x 29.9 inches, 51 lb, 1.2 cu ft, 1000 watts, 400 CFM two-speed vent, one-year limited warranty on the entire appliance. Model number UVM9125STSS is the only meaningful change. GE says the integrated handle and bottom controls make it easy to wipe down, which for a busy family kitchen is more than a cosmetic point: sensor cooking, popcorn, defrost and reheat get hammered daily, and a smooth front panel takes fingerprints better than a keypad-and-crevice layout.

The reason this ranks below the white version is not build, it is price position. This finish sits one tier higher in this set for what is otherwise the same appliance. If a stainless kitchen wall demands a stainless microwave, the trade is worth making. If not, the UVM9125DYWW is the same purchase for less.

Pros:

• Identical build to the overall winner
• Stainless finish matches most modern ranges
• 400 CFM two-speed vent
• Integrated handle for easy cleaning
• Full one-year appliance warranty

Cons:

• Sits one price tier above the white twin
• Only one seller lists it
• Slower seller than four of the six other picks

4. ThermoMate OTR771S — Best premium

The most expensive pick here, with 11 power levels, voice control and a 2-speed 400 CFM vent in the same 30-inch slim footprint.

Best for: buyers who want 11 power levels and voice control in one slim body Skip it if: you already own the GE Profile and are shopping for a second unit

External dimensions on this ThermoMate are 10.4 x 18.7 x 30 inches, essentially the same slot as the GE Profile and Midea 30-inch picks. Interior capacity is 1.2 cu ft, output 1000 watts, vent 400 CFM two-speed. ThermoMate says the unit has 11 power levels between 0% and 100%, a moisture-based sensor cook, one-touch presets and voice control. The finish is stainless steel and warranty is one year from the manufacturer.

The reason this sits at fourth rather than higher is that its specifications duplicate the GE Profile stainless model at the highest price position in this set, and the extras are feature claims rather than measured specs: 11 power levels, voice control, multi-stage cooking. Any of them may matter to you, but none is documented as an outcome. Where this pick genuinely differentiates is depth of cooking control. If you actually use 40% power to soften butter or 20% power to hold soup warm, 11 levels beats the 10 or fewer that most rivals expose.

Pros:

• 11 power levels claim
• Voice control claim
• Multi-stage cooking claim
• 400 CFM two-speed vent
• Slim 10.4 in body

Cons:

• The most expensive pick here
• Feature advantages are all manufacturer claims
• One-year warranty is shorter than nothing else here but not longer either
• No published weight

5. Samsung ME11A7710DS/AA — Most versatile

The only pick with a 550 CFM hood, plus Wi-Fi, voice control, sensor cook and 1100 watts in a 1.1 cu ft cavity.

Best for: cooks with a busy range who want stronger venting and Wi-Fi in the same slim slot Skip it if: you need the extra 0.1 cubic foot of interior other 30-inch picks offer

Where every other 30-inch large low profile microwave in this set pulls 400 CFM, Samsung publishes 550 CFM for this hood. That is a meaningful gap. If you sear, wok-fry or reduce sauces on the range below, ventilation matters more than 0.1 cu ft of interior. External dimensions are 10.8 x 19.1 x 30 inches, which is 0.5 inches taller and slightly deeper than the GE Profile pair, so verify undercabinet clearance carefully. Output is 1100 watts, the highest here.

Interior capacity is 1.1 cu ft, the smallest in the 30-inch group. Samsung classes the unit in the Range Hoods category rather than Over-the-Range Microwave Ovens, which is a hint at how the brand positions it: hood first, microwave second. It is by far the fastest seller of this shortlist. The trade-off is the data sheet gap. No cavity dimensions and no weight are published, and the feature bullets in the listing are empty, so the vent-CFM and wattage figures are what you buy on.

Pros:

• 550 CFM hood, strongest in the set
• 1100 watts, the highest output here
• Wi-Fi and voice control
• Fingerprint-resistant stainless
• The fastest-selling pick of the seven

Cons:

• 1.1 cu ft cavity is smallest among 30-inch picks
• 10.8 in height and 19.1 in depth exceed the GE slim footprint
• No weight or cavity dimensions published
• Categorised as a range hood rather than a microwave

6. COSMO COS-3012ORLP1SS — Best warranty

A 1.2 cu ft, 1000-watt slim in black, with 11 power levels, 7 auto presets and a fully documented one-year limited warranty.

Best for: shoppers who want a black-finished 30-inch slim with a documented parts and labor term Skip it if: you need a stainless or white finish to match neighbouring appliances

The COSMO is the only black-finished pick in the shortlist and one of only two with a fully published weight (51.1 lb). External dimensions are 10.3 x 18.5 x 30 inches, so it drops into a standard 30-inch slot at the same height as the GE Profile pair. COSMO says the unit runs at 1000 watts across 11 power levels, offers 7 auto cook options including popcorn, potato, sensor cook and sensor reheat, and defrosts by weight or time. The listing spells out the electrical requirement, 120V/60Hz, which the other picks generally do not.

Every large low profile microwave here has a one-year warranty. The reason this earns the label is that COSMO documents it as "1-Year Limited Warranty" with US-based customer support named in the listing, alongside the 120V/60Hz spec and the full exterior dimensions. Nothing here is longer or broader, but the paperwork is unusually complete for the category. The trade-off is price position: this sits at the premium end of the set for a spec sheet that otherwise matches the entry-tier picks.

Pros:

• Fully documented 51.1 lb weight
• 11 power levels and 7 auto presets
• Weight and timed defrost
• Only black-finished pick here
• US-based support named in the listing

Cons:

• Premium price position for entry-tier specs
• Black finish limits kitchen match
• Vent CFM not given as a headline figure

7. KoolMore KM-MOT-OP1SS — Best budget pick

The cheapest pick here and the odd one out: a 24-inch cutout with a 1.3 cu ft cavity and a 300 CFM vent.

Best for: a 24-inch cutout in a smaller kitchen or apartment Skip it if: you have a standard 30-inch range and need a matching microwave width

Read the width first. This KoolMore is a 24-inch over-the-range unit, not a 30-inch one, so it fits over a compact range or in an apartment slot where the six other picks physically cannot go. External dimensions are 17 x 23.9 x 16.2 inches, and the weight is 57 lb, the heaviest here. Interior capacity is 1.3 cu ft, actually the largest cavity in the set, and output is 1000 watts. KoolMore says the vent motor is rated at 300 CFM, and the microwave has a stainless front, a rotating turntable with glass tray and a low-profile body versus a cabinet-mounted unit.

The cheapest of the seven. If your kitchen already has a 24-inch cutout, this is the only pick in the shortlist that fits, and you get a class-leading 1.3 cu ft interior in the bargain. If your kitchen has a 30-inch cutout, none of that matters, because the unit will not span the gap. The 300 CFM vent is the weakest here, and it is the trade-off you accept for the smaller footprint and the entry price.

Pros:

• Cheapest pick in the shortlist
• Largest cavity at 1.3 cu ft
• Fits a 24-inch cutout
• Full dimensions and 57 lb weight published
• Stainless front with touch panel

Cons:

• 24-inch width will not fit a 30-inch range
• 300 CFM vent is the weakest in the set
• No sensor cook detailed in the specifications
• Deeper body than the 30-inch picks

How I screened this shortlist

Three tests cut this field down. I ran them in order, and picks that failed the first did not reach the second.

1. Width and height that match a real slim slot. A large low profile microwave has to fit the space a standard undercabinet hood already occupies, which is typically a 30-inch width and roughly 10 to 11 inches of undercabinet clearance. The GE Profile pair, the Midea, the ThermoMate, the Samsung and the COSMO all land at 30 inches wide and between 10.3 and 10.8 inches tall. The KoolMore is a 24-inch unit and was kept only because a real subset of buyers has a 24-inch cutout and no other option in the shortlist fits it.
2. A cavity that earns the word "large". I set the floor at 1.1 cu ft, which is what Samsung publishes. Anything smaller is not a large microwave in any meaningful sense. Every pick clears this bar; the median is 1.2 cu ft, and the KoolMore stretches to 1.3.
3. A documented vent path. Every over-the-range microwave has to move cooking air. I required either a CFM figure or an equivalent hood description in the listing. Six of the seven publish a number. The COSMO documents a two-speed vent fan without a headline CFM, and the trade-off shows up in its section.

What I did not use: price alone, marketing copy about "slim design", or category labels. The Samsung sits in Range Hoods rather than Microwave Ovens on Amazon, and that would have removed a strong candidate for no real reason.

Does 1.2 cubic feet actually fit a dinner plate?

Yes for a standard 10.5-inch dinner plate on the flat, no for stacked containers with lids. The 30-inch slim picks in this set all publish 1.2 cu ft interiors, and the geometry is roughly the same across GE Profile, Midea, ThermoMate and COSMO. A 12-inch platter usually clears the turntable but rotates tight against the door. A 9x13 casserole dish, the size most families own for lasagne and roast vegetables, will not rotate freely in any 30-inch slim here, because the cavity width sacrifices depth to keep the outside height at 10.3 inches.

Three practical checks before you buy:

• Measure the widest platter you actually use, not the biggest one in the cupboard.
• Take the interior height into account for tall mugs and travel bottles; the 10.3-inch exterior height leaves roughly 7 to 8 inches of interior clearance in the 30-inch picks.
• If your household regularly reheats casseroles, the KoolMore's 1.3 cu ft cavity is the only one here that gains meaningful room, and it does so by moving the width down to 24 inches, so verify the cutout first.

Venting: why 400 CFM keeps showing up

Four of the six 30-inch picks quote 400 CFM two-speed venting. That is not a coincidence: it is the target most manufacturers hit for a slim over-the-range unit that has to move air through a shallower duct path than a full-height model. The Samsung ME11A7710DS/AA is the outlier at 550 CFM, and it is the only pick here where the vent is doing measurably more work than the microwave itself.

A quick way to decide how much CFM you need:

• You reheat, defrost and steam. 300 to 400 CFM is enough, and the KoolMore's 300 CFM will keep steam and reheating odours moving out of the kitchen.
• You sear, wok-fry or fry regularly. Go for the Samsung at 550 CFM. The difference between 400 and 550 CFM is not marketing; it is roughly the difference between smoke leaving in one minute and smoke leaving in twenty seconds.
• You cook lightly and want quiet. A two-speed 400 CFM vent on a low setting is quieter than a single-speed 300 CFM at full pull, so the GE Profile pair and the ThermoMate are the quieter options in practice at low speed.

Recirculating installs, where the vent expels air back into the kitchen through a filter rather than outside, lose roughly a third of their effective CFM to filter resistance. Assume the same 30% haircut on any pick here if your run cannot exit through the wall or roof.

What more money buys in this set

Price positions in this set do not line up with capacity. Every 30-inch pick lands on 1.2 cu ft. What the price actually buys is finish, brand and connectivity.

• Entry positions (KoolMore, Midea, Samsung). You get either a 24-inch footprint (KoolMore), Wi-Fi and app control at 1.2 cu ft (Midea), or the strongest vent in the set with Wi-Fi (Samsung).
• Mid position (GE Profile stainless). You pay for the GE Profile build in the stainless finish most modern kitchens are designed around.
• Premium positions (GE Profile white, COSMO black, ThermoMate stainless). You pay for either a documented full data sheet (GE Profile white), a black finish and complete warranty paperwork (COSMO), or 11 power levels and voice control (ThermoMate).

None of the extra money buys more cubic feet, more watts or a longer warranty. If capacity is the deciding factor, the KoolMore at the cheapest position offers the largest cavity in the shortlist, but only if a 24-inch slot works for you.

How to judge a low profile microwave I did not cover

If you are looking at a unit outside this shortlist, five checks separate a real large low profile microwave from marketing copy that borrows the phrase.

1. External height under 11 inches. Above that, it is a standard over-the-range unit, not a low profile one.
2. Interior capacity of at least 1.1 cu ft. Below that, "large" is not the right word.
3. Width that matches your existing cutout, verified to the eighth of an inch. Do not trust the round number in the headline.
4. Vent CFM published as a figure, not described as "powerful". A vague vent claim usually means a weak fan.
5. A warranty term stated in months or years, with parts and labor named. "Manufacturer backed" is not a warranty.

Two extras worth asking about, because listings rarely say: whether the unit ships with a charcoal filter for recirculating installs, and whether the microwave door handle sits at the bottom (easier reach over a hot range) or the side.

The verdict

Two picks lead this shortlist for different kitchens, and the cutoff between them is how hard your cooktop works.

If your range sees mostly reheating, boiling and simmering, the GE Profile UVM9125DYWW is the right buy. Its 1.2 cu ft cavity, 1000-watt output and 400 CFM two-speed vent match or beat the median of the set, its full 10.3 x 18.6 x 29.9 inch dimensions and 51 lb weight are published, and its one-year limited warranty covers the entire appliance. It is the pick with the fewest unknowns on the data sheet, and that matters when the appliance is going onto a wall for a decade.

If your range sees searing, wok-frying or heavy fry work, the Samsung ME11A7710DS/AA wins on the specification that actually decides it: 550 CFM of hood pull versus 400 CFM everywhere else. You give up 0.1 cu ft of interior and 0.5 inches of undercabinet clearance, and you gain a hood that clears smoke fast enough that a smoke alarm stays quiet.

For a 24-inch cutout, the KoolMore is the only pick that fits, and it happens to be the cheapest here.

FAQ

What is the standard height of a large low profile microwave?

Standard height for a large low profile microwave sits between 10.3 and 10.8 inches externally. Every 30-inch pick in this shortlist lands in that window: 10.3 inches for both GE Profile models and the COSMO, 10.4 for the ThermoMate, and 10.8 for the Samsung. A traditional over-the-range microwave is usually 16 to 17 inches tall, so the low profile version reclaims roughly six inches of headroom over the range.

Is a low profile microwave worth it over a standard over-the-range unit?

A low profile microwave is worth it if the space above your front burners feels cramped when you lift a stockpot or turn food in a large pan. The six inches of reclaimed clearance changes how the range works day to day. You lose some interior capacity, typically dropping from 1.6 or 1.7 cu ft down to 1.1 or 1.2, so if you reheat 9x13 casseroles daily, weigh the trade honestly.

Can I fit a 30-inch low profile microwave over a 24-inch range?

Fitting a 30-inch low profile microwave over a 24-inch range is not recommended. The microwave is designed to align with the width of the range below it so the vent captures rising air correctly, and cabinets on either side are usually built to a 30-inch opening. If your range is 24 inches, the KoolMore KM-MOT-OP1SS in this shortlist is the pick sized for you, at 23.9 inches wide.

GE Profile UVM9125DYWW versus Samsung ME11A7710DS/AA: which wins?

GE Profile UVM9125DYWW versus Samsung ME11A7710DS/AA comes down to venting versus capacity. The Samsung publishes 550 CFM and 1100 watts, and adds Wi-Fi and voice control, so it wins for busy cooktops. The GE Profile publishes 1.2 cu ft of cavity, complete dimensions and weight, and a fully documented one-year appliance warranty, so it wins for everyday households where the microwave does most of the work.

What is the biggest mistake buyers make with over-the-range microwaves?

The biggest mistake buyers make is skipping the cutout measurement and trusting the round number on the box. A 30-inch listing can sit anywhere between 29.8 and 30.1 inches externally, and cabinets vary too. Measure your opening at the top, middle and bottom, verify duct location, and check undercabinet height against the microwave's external height plus mounting hardware clearance before you order.

Choosing here is really a two-step call: match the width to your cutout, then pick between the GE Profile UVM9125DYWW for a normal cooking week and the Samsung ME11A7710DS/AA for a heavy one. The GE Profile earns the default slot because its data sheet is the most complete in the shortlist, its 400 CFM two-speed vent handles typical range work without stress, and its 1.2 cu ft cavity is the median size that fits a 10.5-inch plate without argument. Measure the opening, verify the finish against the range and dishwasher next to it, and place the order with confidence.
