An over-the-range microwave does two jobs, and people shop for the wrong one. The microwave part hums for a few minutes at a time. The vent fan part runs for as long as you cook, sits at head height above the stove, and on high is the loudest thing in most kitchens. So we ranked these on the fan first.
The fan has a proper, independent rating. Range hoods, and the over-the-range microwaves that double as them, are certified for airflow in CFM and loudness in sones, at their highest speed and at a slower working speed. We read every over-the-range microwave in the Home Ventilating Institute directory, then went to the makers' spec sheets and manuals for the rest: beeps, the automatic fan, the turntable and the vent options.
Our picks are listed above, with full specifications for each.
How we ranked them
We kept three groups apart and never compared across them.
HVI-certified sones on high. This is the number for frying, searing and boiling. We read it at the high speed HVI tests, at the standard 0.1 inch of static pressure, and we quote the vertical duct figure in the specs, because a model can rate differently through a horizontal duct.
HVI-certified sones at working speed. HVI also lists a slower "working speed" for each model, usually around 100 CFM. For simmering, or for the fan you leave on after cooking, this is the figure that describes your kitchen.
Maker-published dBA. One of our picks has a decibel figure on its spec sheet. We list it on its own. It is in a different unit and does not say which fan speed or cooking setting it describes, so it cannot be ranked against sones or against anything else.
Sones are linear: 2 sones sounds twice as loud as 1. Decibels are logarithmic, where roughly every 10 dBA doubles how loud something seems. There is no reliable conversion between the two, so we never convert. Our sones vs decibels explainer goes into why.
GE, GE Profile, Café, Whirlpool, KitchenAid, LG and Samsung do not appear in the HVI directory. They certify their over-the-range fans through the Association of Home Appliance Manufacturers instead. We left them out of this ranking so that every sone figure here comes from one directory, and we cover their beeps below. Sharp and Panasonic are in the HVI directory, but none of their listed models beat our picks: Sharp's SMO1759JS is certified at 6 sones on high through a vertical duct, and Panasonic's NN-SU158S at 7.5.
High speed: the spread is small
On high, over-the-range microwaves are much alike. Almost every model in the directory is certified between 6 and 8 sones. The one clear outlier is the Frigidaire FFMV1645TS, and its sister models, at 4 sones.
That 4 sones comes from a smaller fan. It is certified at 170 CFM vertical and 160 CFM horizontal, against 230 to 310 CFM for most full-size models. Quiet costs airflow here, as it does with range hoods. If you cook on electric and mostly want steam gone, the trade is a good one. If you sear steaks on a big gas burner, it may not keep up, and you will be running a small fan at its limit rather than a bigger one partway.
Watch the marketed airflow too. Frigidaire markets the FGMV17WNV at "2-Speed 105 / 300" CFM, and HVI certifies it at 230 to 240 CFM on high. Bosch lists 385 CFM for the HMV8054U, and HVI certifies 270 to 280. The certified figure is the one measured at a stated pressure, so use it.
Working speed: where the real differences are
At working speed the gap widens. The Frigidaire Gallery FGMV17WNVF is certified at 1.2 sones at 100 CFM through a vertical duct, and the FFMV1645TS at 1.3. A handful of budget models from Magic Chef, Vissani and Seasons are certified at 1 sone, but at 90 CFM through a horizontal duct.
The Bosch HMV8054U takes the other route. It is certified at 2 sones on working speed, but at 140 CFM, the most working-speed airflow of any over-the-range microwave in the directory. If you want to clear a pan of onions without switching to high, a working speed that moves more air may be quieter in practice, because you reach for high less often.
Duct direction matters as well. The FGMV17WNVF is certified at 7 sones on high through a vertical duct and 6 through a horizontal one. The Bosch goes the other way, 7 vertical and 8 horizontal. If you already know which way your duct runs, read that line.
For the microwave itself, published figures are almost nonexistent. Frigidaire's spec sheet for the FMOS1846B lists "Sound Level 60 dBA" under General Specifications, and the Canadian spec sheet for the Electrolux EMOW1911A lists the same 60 dBA. Neither says whether that is the magnetron, the cooling fan or the vent, at what distance, or to what standard. Take it as a sign that the maker measured something, not as a number to rank on.
The hum has more than one source. Bosch's HMV8054U manual says the cooling fan "runs during all cooking modes" and can be heard. That cooling fan is separate from the vent fan, and it is why some over-the-range models keep whirring for a minute after the door opens. Our main guide to the quietest microwaves covers the hum, the door and countertop models in detail.
The fan that turns itself on
This is the noise owners do not expect. Every manual we read for these picks describes a heat sensor. If the cooktop below makes the microwave too hot, the vent fan starts on its own at low speed, and you cannot turn it off until the parts cool. Frigidaire's FMOS1846B and FFMV1645T manuals both say that "the vent cannot be turned off" when this happens. The FGMV17WNV manual adds that the fan "may stay on up to an hour to cool the oven."
So after a long simmer on a front burner, expect the fan to keep going through dinner. This is why the working-speed rating matters so much: the automatic fan runs at the low setting. GE also says its vent fans can change speed or get louder while running, which it describes as normal when the fan is working against back pressure in the duct or filter.
Ducted or recirculating
Most over-the-range microwaves can either vent outside or blow the air back into the room through a charcoal filter. Frigidaire's FGMV17WNV spec sheet says the ventilation system "is preset to recirculate air inside with no ducting system required", so check which way yours is set up at installation.
For noise, there is no rating to compare. Broan-NuTone, which makes range hoods and HVI-certifies them, says in its FAQ that "There is no national standard for the measurement of CFM or Sones on a non-ducted hood because the air is not exhausted, it is re-circulated." The HVI figures in this guide are for ducted installations. A recirculating setup also returns heat and moisture to the kitchen, as Broan-NuTone notes, and the Frigidaire manuals include a filter indicator that is on by default for recirculation.
Beeps and how to mute them
Over the range, the beeps are right at ear height. What the manuals and help pages say:
- Frigidaire. All three Frigidaire manuals we read have a sound setting with an off position: Low, Normal, High or Off on the FMOS1846B and FFMV1645T, and Low, Medium, High or Off on the FGMV17WNV.
- Bosch. The HMV8054U's basic settings let you turn key sounds on or off. The manual still says "4 beeps sound" at the end of cooking and when the kitchen timer ends, and we found no setting to silence those.
- GE, GE Profile and Café. GE says models with variable beeper volume use a Sound Level pad with 0 to 3, where 0 is off, or a Mute On/Off pad. Some GE models also sound a cooking complete reminder, a beep once a minute after cooking ends, until you touch Clear/Off or open the door.
- Whirlpool, and its sister brands. Whirlpool's help page for over-the-range models says alerts vary by model, "but most audible signals can't be turned off."
For LG, Samsung and KitchenAid, check the manual for your exact model before buying. Search it for "sound," "mute" or "beep."
Turntable and door
The turntable makes its own low rumble, and a worn or dirty roller ring makes it worse. Two of our picks let you stop it for flat dishes: the Frigidaire Gallery FGMV17WNVF lists Turntable On/Off, and the Bosch HMV8054U manual has a turntable on/off setting. Frigidaire's manual says the turntable is on whenever an auto cooking program is selected.
No over-the-range maker we checked publishes a door noise figure or makes a quiet-door claim. The only measured door we found in the category is on a countertop model, in our main microwave guide.
Should you swap it for a hood?
If the fan is what bothers you, a dedicated hood is the bigger fix. The quietest hood in our range hood guide is certified at 4 sones while moving 470 CFM, nearly three times the air of the quietest over-the-range microwave on high.
But a basic hood is not automatically quieter. Broan-NuTone pitches its AR130SS as giving "20% more coverage over the cooktop than the standard over-the-range microwave combination units", and its product page lists 2 sones. HVI certifies 2 sones at its working speed through a 7-inch round duct; on high it is certified at 7 to 7.5 sones, much like a microwave. If you do swap, compare the certified high-speed rating, and see range hoods for an open-plan kitchen for how to read the sones at the speed you actually cook on. If the hood will hang under the same cabinets, our guide to under-cabinet range hoods does that for each model; the Zephyr Valina 290 has the lowest certified high speed it found, 3.5 sones at 260 CFM, enough for a 30-inch cooktop.
What it sounds like in the kitchen
Broan-NuTone gives a rough scale for sones: 1 sone is "The refrigerator running in your kitchen", 3 sones is a face-to-face conversation, and 4 sones is "The level that most listen to the TV in their home." By that scale, the working speeds of our picks, 1.2 to 2.5 sones, sit between a fridge and a conversation, and every microwave on high is louder than the TV.
In a closed kitchen, that may be fine. In an open-plan room the fan competes with talk at the table, and our guide to planning a quiet open-plan kitchen shows how the hood fits with everything else that runs while you cook. Remember too that a spec-sheet figure from one maker cannot be lined up against another's; see why you cannot compare dB ratings across brands.
What quiet costs
Airflow. The quietest fan on high moves the least air. Price. The Bosch that moves the most air quietly costs the most of our picks. Choice. The quietest HVI-rated models are mostly Frigidaire, and we could not load Frigidaire's own site to confirm prices. Installation. Every certified figure assumes a proper duct; a long run with elbows, or a recirculating setup, changes what you hear.
How we chose
We downloaded the Home Ventilating Institute certified products directory, generated September 23, 2026, and read every listing in its microwave subcategory at both speeds and both duct directions. For each pick we read the maker's spec sheet and use and care manual for capacity, marketed airflow, sound settings, the automatic fan and ventilation options. Where a manual was only available as a retailer's copy of the maker's document, we say so in the sources. For GE and Whirlpool beeps we used the makers' own help pages.
We did not measure any of these microwaves ourselves. Every sone figure is HVI's certified rating, every other figure is quoted from the maker's own documents, and mute and fan behavior is paraphrased from the manuals, so check the manual for your exact model.
