An air fryer making noise is usually just its fan. Philips says a sound like a fan rotating very fast is normal, and Swan says some noise from the fan and internal components is normal. Rattling, fluttering, or a noise louder than or different from the usual one is another matter: the makers say check for crumbs and loose items, then stop and contact them.
Below: what each maker calls normal, how to check a rattle, which beeps you can mute, and why some fans run on after switch-off.
Air Fryer Making Noise: What Each Maker Calls Normal
| Maker and source | What it calls normal | Figure it gives | What it says is wrong |
|---|---|---|---|
| Philips, support page | A fan rotating very fast; it keeps internal parts cool. | Up to 65 dB, likened to an average vacuum cleaner. | A louder or different noise, such as fluttering or shuffling: a part is loose inside. |
| Swan, support page | Some noise from the fan and internal components. | None given. | Rattling: check for loose parts, crumbs in the basket or items touching the fan. |
| Xiaomi, Smart Air Fryer 5.5L FAQ | Noise mainly from hot-air circulation. | About 50-60 dB(A) when in use. | No next step given. |
| COSORI, TurboBlaze manual and listing image | Fan speeds 1 to 5, set by the function; fan speed cannot be customized. | 27 dB on fan speed 1, 53 dB on fan speed 5. | Its blog lists unusual noises among signs to unplug it and let it cool. |
| Breville, countertop oven support page | Relatively loud fan on air fry; a low hum; occasional popping as it heats or cools. | None given. | Rattling rather than smooth airflow. |
The Breville page covers countertop ovens with air fry, not basket air fryers. None of these pages says how its figure was measured or from how far away, so the numbers do not rank brands; for a like-for-like comparison, see Consumer Reports’ lab ratings below.
Why It Is Louder on Some Settings
On the COSORI TurboBlaze, the cooking function sets the fan speed: Air Fry, Roast, Broil and Frozen use the highest speed (5), Preheat and Reheat use 4, Bake 3 and Dehydrate 1. So it is meant to be louder on Air Fry than on Bake. The COSORI TurboBlaze review covers what owners say about its noise.
A fan that cuts in and out after cooking may be keep-warm mode: Philips’ HD925x manual says the fan is on for three seconds every minute during keep warm.
Rattling, Fluttering or Something Loose Inside
The makers’ checks that need no tools:
- Unplug it and let it cool. COSORI’s blog says to do this if you notice unusual noises.
- Empty the basket and drawer. Swan lists crumbs in the basket and items touching the fan. Debris around the element is covered in how to clean an air fryer.
- Weigh down light food and liners. Ninja’s manuals say the fan occasionally blows lightweight foods around (the rattle link is my inference). Philips says lightweight baking paper can be lifted by the airflow and touch the heater.
- Check the crisper plate sits properly. COSORI says the Pro LE plate’s 4 rubber stoppers keep it fitted to the bottom of the basket, and Gourmia says the GAF858’s silicone bumpers must be left on during use. The noise link is mine, not theirs.
- Check the surface. COSORI’s Lite manual and Breville both ask for a flat, stable surface.
- If it still rattles, stop. Swan says to stop using the appliance and contact support if the noise is loud or unusual.
Humming, Buzzing, Ticking and Popping
Of the maker noise pages I read, Breville’s is the one that names these sounds. It says a low buzzing or humming sound is generally normal, and that occasional banging or popping during heating or cooling comes from metal parts expanding and contracting.
Ticking can be a mechanical timer: Consumer Reports notes that some air fryers use analog timers whose ticking can be a nuisance. Spitting during cooking is more likely the food. COSORI’s manuals say liquid-marinated foods create splatter and excess smoke, so pat them dry; the link to popping is mine. If there is smoke too, see why an air fryer smokes.
Clicking is the gap. None of the maker noise pages I read mentions it.
Why the Fan Keeps Running After You Switch It Off
GoWISE’s GW44803 and GW46690 oven manuals say that when the time runs out, cooking stops but the fan continues running for 20 seconds to cool down the unit. Instant’s Vortex Slim manual says that after Cancel, depending on the unit’s temperature, the internal fan may keep running to cool it, and the Vortex Plus 10-qt oven manual says the fan blows to cool the oven when a program ends. Breville says the same of its countertop ovens.
The COSORI, Ninja, Philips, Chefman and Dash manuals I read say nothing either way, so I cannot tell you whether those fans run on. If the air fryer switched itself off early, see why an air fryer turns off by itself.
Why Your Air Fryer Keeps Beeping, and How to Mute It
Most beeps are reminders: food done, time to shake, or food still waiting. Whether you can mute them depends on the model:
| Maker and model | When it beeps | Turning the sound off |
|---|---|---|
| Instant Vortex Slim, Vers Zone and Dual | At the end, then about once a minute as a reminder (for 10 minutes on the Slim and Vers Zone). | Hold two buttons for 5 seconds (Slim: Temp and Time). Safety or error alerts stay on. |
| Instant Vortex Plus 10-qt oven | Reminders 5, 30 and 60 minutes after the program ends. | In Standby, hold the Temp and Time minus signs for 3 seconds. |
| COSORI Lite, LI401S and Pro LE | 3 beeps at the end; a 5-beep Shake Reminder that repeats after 1 minute (LI401S, Pro LE). | No sound-off instruction in these manuals, or the TurboBlaze and SE601S manuals, but the Pro LE and SE601S let you switch the Shake Reminder off with its button. |
| COSORI Premium II Plus and Twinfry | Shake Reminder. | Premium II Plus: hold Bake and Shake for 3 seconds. Twinfry: hold TEMP and TIME for 3 seconds. |
| Gourmia GAF858 | Guided cooking prompts. | Hold STOP/CANCEL; it still beeps for guided cooking prompts. |
| Ninja AF100, AF160, DZ401C and EZView Max XL | Food done; on the DZ401C, also when the other zone starts cooking. | No sound-off instruction in these four documents or the AF100 support FAQ. |
| Philips (HD9285, HD986x, NA150 and other listed models) | A shaking reminder on presets and auto programs. | No sound-off instruction in the four Philips manuals I read; on the NA150, the shaking reminder button turns the shake alerts on or off. |
Ninja is unresolved: T3 reports that holding Time and Temperature for up to five seconds in standby shows “Sound Off” on Ninja and Instant Pot air fryers. The Ninja documents I read describe no mute, and in the Ninja DZ201 review one owner says Ninja told them the beeps cannot be silenced. Trying the button hold costs nothing; if your model ignores it, ask Ninja.
Which Air Fryers Are Quietest
Consumer Reports puts each air fryer on the same surface in its lab and measures the sound several times during operation, noting the peaks. The models it lists as earning top ratings in its noise tests are the Chefman Accufry RJ38-SQPF-5T2P-W, Chefman RJ38-2T, Cosori Lite CAF-LI211, Dash Tasti-Crisp DCAF260 (see the Dash Tasti-Crisp review), Pioneer Woman PW6136170192004, Tabitha Brown for Target 8 Qt. Digital and Typhur Dome 2 AF03.
At the other end, Consumer Reports gives the Instant Vortex 4-in-1 it tested dismal scores partly for its loud operational noise, saying it sounds like three microwaves running at once, though that is not the model in the Instant Vortex Mini review.
Homes & Gardens and Real Homes both say the COSORI Pro LE’s AirWhisper technology keeps it under 55 dB; neither says how that figure was measured. For picks where noise is a criterion, see the best air fryers guide.
When to Stop Using It and Contact the Maker
Besides a persistent rattle, two signs mean stop. COSORI’s blog says unusual noises with electrical smells or sparks mean unplug it and let it cool (smells alone: why an air fryer smells like plastic). Ninja’s AF100 and DZ401C manuals say an “E” message means the unit is not functioning properly and to contact Customer Service.
Check recalls too. The US Consumer Product Safety Commission’s recall 23-130 covers COSORI air fryers whose wire connection can overheat, and recall 24-159 covers Insignia air fryers and ovens that can overheat. Neither notice mentions noise as a symptom, but both say to stop using a listed model immediately.
The Repair Debate: Open It or Call the Maker?
iFixit’s guide for a loud COSORI TurboBlaze says to tighten loose screws, check the fan and, failing that, replace the control panel, and its Ninja AF161 guide blames rattling on a loose basket sensor or debris in the fan. The makers point the other way: Philips says to contact it, and COSORI’s blog says not to repair electrical or heating components yourself. I would follow the makers, especially under warranty, and leave the casing closed.
How This Page Was Put Together
This page is based on maker manuals and support pages, not on testing; I do not own or test air fryers. The sources are manuals and support pages from eleven makers, plus Consumer Reports, T3, iFixit and the CPSC.
What I could not establish: whether COSORI, Ninja, Philips, Chefman or Dash fans run on after switch-off, whether Ninja basket air fryers can be muted, and what causes clicking. The Consumer Reports pages I read give ratings, not decibel figures.
The Verdict
Loud fan noise is what the makers call normal; Philips puts its own at up to 65 dB. A rattle, flutter or new sound gets the no-tools checks above, then a call to the maker, not a screwdriver. Beeps can be switched off on several Instant, COSORI and Gourmia models. Everything else on the appliance is in the air fryer hub.
Frequently Asked Questions
Is it normal for an air fryer to be loud?
Yes, within limits. Philips says a sound like a fan rotating very fast is normal and can reach 65 dB, about as loud as an average vacuum cleaner. Swan and Xiaomi also call fan and air-circulation noise normal. A rattle, flutter or sudden change in the sound needs checking.
Why is my air fryer rattling?
Swan lists loose parts, crumbs in the basket and items touching the fan. Unplug it, let it cool, empty the basket, check the crisper plate sits properly and weigh down light food or paper. If it still rattles, Swan and Breville say to contact customer support.
How do I turn off the beeping on my air fryer?
It depends on the model. Instant’s manuals give a button hold of 3 to 5 seconds that turns sound off but leaves safety or error alerts on. COSORI’s Premium II Plus and Twinfry and Gourmia’s GAF858 have one too. The Ninja documents I read describe no mute.
Why does my air fryer fan keep running after I turn it off?
Some are designed to cool down. GoWISE says its ovens run the fan for about 20 seconds after cooking, and Instant’s Vortex Slim and Breville’s ovens say the fan may keep running to cool the unit. On some Philips models, keep-warm mode also switches the fan on in bursts.
Why does my air fryer make a popping noise?
Breville says occasional popping while its ovens heat or cool is normal, from metal parts expanding and contracting. Spitting during cooking is often the food: COSORI says liquid-marinated foods create splatter, so pat them dry. COSORI says unplug it for smoke not clearly from food or a strong burning smell.
Which air fryer is the quietest?
Consumer Reports gives top noise ratings to seven models, including the Cosori Lite CAF-LI211, Dash Tasti-Crisp DCAF260 and two Chefman models. Makers’ own decibel claims, such as COSORI’s 27-53 dB for the TurboBlaze, are not measured the same way, so they cannot rank brands.
