Attempting to FIX - AIR FRYER NOISY FAN

In this Tea Break Fix I look at a CORSORI Air Fryer with a very noisy fan. I previously fixed this item as the door safety switch had broken, but viewers mentioned that the fan didn't sound right, so I decided to look at it again to see if we can find out what is causing the noise and if it is fixable.

Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.

[@GrimReaper190889]

Hey Vince, there is a second reason for the other fan: You want to remove the humid air from the inside, because otherwise you would be steaming the food instead of baking / air frying it

[@grahameaves3298]

This fix has the added benefit of "not covering your food with a light dusting of ground aluminium". From a general google search of shaded-pole motors it does look like they usually have a non-metallic spacer against each phosphor bronze bush.

[@kareno8634]

Thanks for name 'phrase', "shaded-pole motors". Added to vocabulary. Better than search via description.

[@wayne7521]

Well said , same motor you'd find in a electric can opener too.. nasty motors they are ... my friend electrocuted himself ... dozy sod ... held knife near the coil section.... Guess he didn't understand electro magnetism... blind for 3 days ... he was lucky .

[@vitor900000]

Aluminium is more expensive. Its most likely iron.

[@wayne7521]

@@vitor900000 er say what .... what's aluminium got to do ,with vinces fix... the o.p. was been ironic and sarcastic .look them words up first .

[@vitor900000]

@@wayne7521 "not covering your food with a light dusting of ground aluminium" I assume he is talking about food poisoning here so: As I said aluminium is more expensive so the correct is iron dust. The take away here is that aluminium is toxic while iron is not.

Vince, I've been watching your videos for about a year now and the number of videos I've seen of yours where you would have been able to do an easier and probably better fix (such as this fix) if you had a 3d printer. With this fix you would be able to simply print a new plastic washer to fit on the bottom to space it back out again. Also things like the RC car you did a couple of days ago, you would be able to 3d print a new cog out of Nylon filament. I've been 3d printing now for around 10 years and have used my printers for so many household repairs and made additional bits and pieces for my hobbies, I wouldn't be without one now! Don't get me wrong, your lateral thinking is awesome and some of the fixes you do are properly amazing. Keep up the great content. Best Wishes, Paul - Aspie_Geek_UK

[@Dumpflam]

agreed. but i dont think vince has the time to mess with a 3d printer. even if it is a plug and play one like bambu labs.

[@antonyfiori2931]

Maybe if someone sent him a broken one to fix haha

[@Aspie_Geek_UK]

@antonyfiori2931 now that's an awesome reply 🤣

[@devttyUSB0]

Oooooh! The come-back we've been waiting for! The fan sounds so much better and what an awesome inventive fix!! Great job Vince!

[@MrDjc44]

Fantastic fix vince,not many youtubers read the comments and do what the people ask for,it just goes to show how much you respect your subscribers and their views,keep up the great work my friend

[@Mymatevince]

Thank you. Nearly ALL my learning is from the KZbin comments section 😂 I'm lucky that I started so long ago that I gained viewers that really know their stuff and are willing to help me out. Amazing really😎

[@Ea-Nasir_Copper_Co]

One of the things I’ve learned in sixty years (!) of life is that nothing can enrage a man quite like an unexpected lefty-tighty righty-loosy bolt.

[@uselesseater5916]

You know you are right!

[@theatheisthammer]

It looks like the motor has shifted on the shaft . You could knock it back through a little as it's compression fitted on the shaft

[@Cha-chingWV]

I've been watching since the beginning.... you've come a long way in terms of expertise vince. You really can fix pretty much anything now given time and parts.

[@wisher21uk]

Nice fix and problem solving thanks Vince 😊

[@philclarke8080]

Hey Vince love your videos, discovered them a few weeks ago when I had Covid again. I now watch every new one! Really interesting stuff!

[@davearthur514]

I believe the washer on the fan is made of mica, they have high temp. resistance.

[@snafu2350]

It could be glass fibre board or any other similar fibre washer for hi-temp application; mica tends to be only used in electronics or similar 'cause they're expensive & relatively fragile

[@TerryLawrence001]

The extra fan cools the top of the metal shield around the heater. The cool shield then condenses the hot oil fumes and stops the oil from exiting the vent hole. Remember, there is a bunch of oil particles floating around in the hot oil.

[@nagisaian]

I love your problem solving its so therapeutic

[@Isoldael]

Excellent video, I love how you talk through your thought process instead of just showing us how to do it. I'm new to the channel, but have you heard of repair cafes? I think they match great with what you do!

[@MadManMcGirt]

you are correct. the plastic fan is simply a cheaper way to deal with the heat over insulation. Insulation would certainly do the job properly. the difference in price is very small

[@Eggit13]

Well done Vince!

[@tomharris1457]

Nice fix. Good detective work.

[@alfafan164]

Well done Vince ☺️

[@wayne7521]

Nicely done vince !!

[@clivewitney3557]

Hi Vince fascinating watching your videos.. All ovens will have an 'extract' vent of some sort as you need to get rid of moist air otherwise you will be steaming not baking the food😊

[@billyk5038]

Well done Vince. Good fix. I'm sure it will be a permanent fix.

[@bradmarthafocker4285]

[@LegendSpecialist]

Nice fix

[@tleonard410]

Definitley an improvement i wouldnt say its fixed but you know what the problem is now

[@599miata]

Good job there, mate.👍👍

[@rohan8611]

Hey Vince just did a similar repair for my microwave oven as the fan was making a racket, i just cleaned the assembly and added high temp grease/bearing grease and the noise vanished. In case you open it in the future you can add a dab of high temp grease instead of oil.

[@Woffy.]

Shaded pole motors generally have a lot of axial play and this is not a problem when they are running as the magnetic field in the stator aligns the rotor. If the motor is noisy on run down then this is because the rotor is dropping from the loss of magnetic field and then binding. Bent plastic fans, use a knife to cut some shallow slots on the high side and hot melt back together whilst flat. The shaft may have walked down the rotor when it was dropped, apply some kinetic therapy to moves shaft.

[@GGigabiteM]

The magnetic field in the rotor has nowhere near enough strength to keep it centered. Any axial load is going to push it to one side or the other, where it will cause friction, heat and wear. Even in horizontal operation, these things wear out quickly because manufacturers make them with no oil ports, and these motors burn oil by design with their nasty sleeve bearings. If they're in a dusty environment, they wear out even faster because the dust mixes with the oil and makes liquid abrasive.

[@Twintania]

I love the more mechanical fixes you were saying in the rc car video how you find fixing battery contacts to be boring. Myself I find fixes boring when it's mostly circuit boards and soldering it all just blends together for me

[@Birdie2360]

As much as I love your fixing videos I wish you would use correct tools to take things apart like stop using pliers to undo bolts please use a proper bolt bit as then stops damage to the bolt head

[@billbliss7407]

I really enjoy your videos, and really like that you encourage people to fix things rather than throw them out. Thanks for sharing all you do! From other videos, I know you usually have a boat-load of nylon gears -- I was wondering if one of those would have been a better spacer for both heat resistance and wear.

[@Mymatevince]

Why didn't I think of that!!!!!!!! Can't believe I didn't think to use a cut up gear. Embarrassed now🤣 Thanks for letting me know👍

[@zul_fix]

Hey Vince, i have a pellets insert fireplace that has an engine very similar to that one, they used bearings on it and instead of a spacer theres a small spring to avoid the motor to woble just like that one. Also the small fan is metal instead of plastic like that one. Tks for your vídeos!

[@davidstevens3355]

Can’t beat a few metal grindings on your chips 😂 Well done

[@wayne7521]

Mix with the iron in your blood ,and voila ...defo don't light them farts 😂😂😂😂😂

[@protox07]

I like your videos

[@Phiyedough]

Thanks, people keep talking about air fryers but I had no idea what they were. I don't think I would ever want one.

[@samuelfellows6923]

I refer to them as a “micro oven” [as that is what they really are], they are a current trend of being a “healthier” alternative to the [more traditional] deep fat/oil fryers

[@Frogdog69]

Great fix😅

[@rodevz7815]

Nice

[@markshellard5894]

Sounds like a brick in a tumble dryer 😂

[@TheStanHill]

I would just move the whole nylon washers assembly from the top to the bottom part. The rotor sits on the bottom “bearing” all the time and there will be the same play as before, so we will have like 4mm gap between the rotor and the top “bearing” - they will never touch.

[@paulstaf]

Those motors are usually mounted with the shaft horizontal for use in fan applications. I don't think it was designed to be used in the vertical shaft orientation and hence it doesn't have proper thrust washers/bushings.

[@devjon123]

I used to repair Electric Motors from several hundred Kw down to ones smaller than that shaded pole motor in the Air Fryer. I routinely used to repaair shaded pole units and have stripped hundreds of them down. It was often far more practical ( and cheaper ) to fit a new Motor. There is ( was? ) a UK company called REMCO who supplied all our shaded pole motors. The second ( smaller ) metal fan thats located on the shaft inboard of the main blower fan acts as a heatsink to stop the motor overheating ( the air being channeled over the metal fan blades draws the heat from the motor shaft ) there's quite a few with a similar design that are used in gas burners / industrial ovens etc. As the unit is vertically mounted it is possible ( though very unusual ) for the rotor to creep down the shaft. If you see it is out of alignment with the Iron core that it sits centrally in then it's possible to put some Loctite 638 on the shaft before tapping the core back into position.

[@GertrudeFilthbasket]

18:49 when pressing in a round object in a vise, use a socket to distribute the force. 👍

[@bobmarley_1979]

I had the same problem . The tin blades would bend and scrap on the housing as it got hot . I ended up making the blades narrower about half the size . no issues since 😆

[@ralphj4012]

Good workaround. That motor was never intended to be mounted upside-down without requiring additional parts. Margot would be seeing pink (17:33).

[@howsthis4aname]

Large " convection " ranges (ovens) also expel their cooking heat to the atmosphere. This is just a tiny version of the same principle of removing moisture and excess heat along with circulating the heated air within the cooking space. It doesn't usually stop people from cooking in the summer months. It kind of baffled me, why you didn't safely plug it in and run it, when you initially took the top off? It may have pinpointed the area of grinding so much quicker. I do believe you are correct that a manufacturing error is the root cause with a missing washer of some sort on the downside of the motor /fan assembly and that noise is why it was returned. This type of appliance is classed as disposable for sure, so usually, if it breaks it gets binned. Entertaining repair, nonetheless.

[@quantumleap359]

Those cheap motors are also called "shadow pole" motors. Used in many applications. Not very efficient, but they are small and have enough power to run many gadgets. This one, unfortunately, was assembled incorrectly from the factory. Good repair Vince.

[@Mymatevince]

Thanks Quantum Leap 👍👍

[@andybrooks7228]

Fan ovens have a cooling fan as well as a heat circulating fan.

[@rf159a]

In the states we call the grey plastic item you cut up to make a bushing, 'Plastic Anchors'.

[@ickilla]

I just seen the last video and knew this one was coming

[@jca111]

I assumed the second fan was to remove steam. If you didn't the food would be soggy, particularly in such a small area.

[@electronash]

8:30 - Be a bit wary with some washers etc. that look like that. I know Asbestos is banned for most things now, at least in the UK. But it's possible that washer is made from some Beryllium alloy maybe, which is almost as bad. Then again, I guess the cooker would need to be "food safe", so maybe it is just some inert fibreglass or high-heat polymer stuff? Bascially, just don't crunch it up and breathe it in. lol

[@electronash]

They do still use beryllium spacers on the magnetron in many microwave ovens, AFAIK. But usually they colour them pink/red to make it more obvious.

[@ForDBssake]

that's the same motor as my space heater. makes sense, it's loud too.

[@GavinColbourne]

11:09 most compact air fryers like that I believe uses 2 fans to create a vortex effect for a more effective cooking and it is only waste heat the expels out of the back

[@chudsonpl]

Secondary fan is for cooling the case. Big kitchen ovens have them too ( all those mounted in the furniture or special pizza ovens like effeuno )

[@chudsonpl]

That fabricated plastic wahser you added might melt from temperature the shaft will transfer from the heating element. That's why original are nylon not plastic 🤔

[@cofreth]

Maybe you may use fibre washer and add more to reduce the stator coil clearance between Bush bearings.

[@matteo_z]

19:16 that type of rotor is called squirrel-cage (it's quite common in high voltage alternated current applications, even if I was expecting a universal motor), and it does not have coils inside. If it had coils in the inside, you would also have brushes at the top, that's the easiest way to tell.

[@savedaz]

I reckon there’s a Rolls-Royce video coming up! looking at your hands Vince ❤

[@GadgetUK164]

Brilliant job again! I would be tempted to get a nylon washer now you know that's the issue, and perhaps grease it with something that's safe regards food - maybe some kind of edible grease lol?

[@HHGTV]

Hey Vince, you are my go-to for tech advice. I recently bought a PSP Street (E1004) and my screen has some scratches and one tiny green dead pixel dot on the bottom left area. I was wondering if I could send you my console for you to replace or fix the screen. Perhaps even make it into a video for everyone. If you are unable to I understand, since you seem quite busy with many other fixes. Your videos are very calming to watch.

[@mitchd949]

I wanted to hear the spool down after you turn it off. Before the fix, you could literally hear grinding and metal-on-metal friction as it spooled down to a stop.

[@Jayandthegames]

Fun fact, the motor used for that fan is the same used in exhaust fans for bathrooms.

[@RoStepMusic]

New video already? Yesss ❤

[@oldbatwit5102]

Another good video. I don't suppose you have any experience in fixing worn hip joints?

[@Mymatevince]

😂

[@borisk6969]

Hi Vince, you've got all those nylon gears you could have made a nylon spacer from?

[@korgied]

Fans are almost always left-hand threaded.

[@PeterFalconII]

Metal fan in hot oven connected to metal shaft going into electrically powered fan motor thats going to heat up itself. The motor will need cooling fins without a hot oven below. So with a metl fan and shaft the fans going to burn out very quickly with no cooling. No amount of insulation will stop the heat going down the shaft.

[@adrianbestboy98]

as I said every single time when you film your doorbell rings😂

[@Mymatevince]

Guaranteed 😂

[@sambaker3233]

That washer is made of mica, which is a mineral. It has good electrical and heat insulation properties. Mica is used everywhere, from electrical to cosmetics. Formica is the synthetic version of Mica

[@CRAZYGTASA]

would it not be easier to put the top bigger white washer with the lip on the bottom as the motor is being pulled down cuz of gravity and the top can have a smaller one as it wouldn't be hitting the top ?

[@anthonydenn4345]

I was thinking the same thing. But I think you would also need something like a brass washer between the white washer and the bottom bushing to stop the plastic getting chewed up 😆

[@FrankJCarver]

The same type of motor used in old BSR decks. An induction motor.

[@CD_Player_91]

You may of been able to slide one of Your spiral gears straight on if one is big enough ⚙️

[@omnydrean]

I thought you might have used a nylon gear from you rc car video to use as a spacer.

[@greasemonkey5637]

Someone needs to shout Vince a socket set, so he doesnt use a pair of pliers to undo nuts.

[@65bug519]

the biggest problem is the shaft getting hot and usually they put a metal fan on the inside to dissipate heat so it does not damage the bearing,

[@vitor900000]

I would have placed the original spacer that was on top on the bottom since the fan naturally tends to slide down due to its orientation.

[@zynaps666]

What about all the nylon gears you used in the RC car video. Maybe repurpose one of the flat ones? Drill one out and cut it to size.

[@Mymatevince]

Yeah, that would have been much better, I just did not think of using them!!!! I was wracking my brains thinking of what to use and I had a whole box of nylon gears just under my right knee 😂👍👍

[@Lightshaft1]

Did you take account of the airflow pulling the fan shaft up or down, could that white thrust washer just have been on the wrong end of the shaft?

[@UgurOnderBozkurt]

11:49 to avoid overheating the motor! that plastic fan for "cooling" for motor. (oops you already say that :)

[@laurencebushby713]

every oven has a steam vent ! and you could have used a metal washer with the nylon bush next to bearing if you wanted

[@UgurOnderBozkurt]

8:38 to stop heat from resistance to motor.

[@foxdata]

You need a 3D printer, Vince!

[@dawn1berlitz]

i have this issue with a non corosori air fryer i plan to replace the fan blade at some point

[@dazer123]

You have plenty of nylon gears ?

[@radio-ged4626]

Well, it's better but it will never sound as silent as an AC motor with proper bearings. Maybe a bit of fine moly grease (not the sort you use on your Rolls 😃) on the shaft where it fits those cheap brass alloy bushes would make it slightly quieter and last longer.

[@Popeyes66]

I bet your Dad is thinking . . ." oh no,what rubbish is that boy dumping on me now " And . . " when will that Roller be gone from my yard "

[@jonathaningram4672]

I was thinking a couple of squirts of lithium soap grease would have improved it further and probably make it last longer, I used that on a catering fridge before and it's as quiet as a church mouse.

[@kareno8634]

7:32 Push Tabs. *Thank You!* never knew. 16:31 any chance what broke fell out when handle was fixed? missig [plastic] 'washer' or ... motor was *jolted* Out? Part of washer needs to extend so bearing Bracket can rest on it. .... *Very* much better! *Hail Vince!* Not just Skill, but Bravery & Brain Cell ideas applied, when wanting something back together, working. Oh the destruction i see in my future. lol

[@endisforever22]

No we have ninja double tray Airfryer that still exhausts to the outside i can only imgine its to do with the air flow part of air frying rather than heating that the hot air cooks the food by flowing all round it rather than just the heat like an oven would

[@TerryLawrence001]

That fan looks very similar to a bath fan. I think you will find these fans very inexpensive to replace as they are very common in every day life. there are even bushings and spacers available. I repair the bath fans in our buildings because they are discontinued and a retrofit requires an expensive renovation.

[@dDoOyYoOuUtTuUbBeE]

Yes and cooking ranges should be fully enclosed because they heat the kitchen, so inefficient, and people cooking should wear thermal sealed suits. The fiber washer is a thermal isolator between the cooking space and the motor.

[@TimBrownie]

Yep, That's what she said.

[@peekpt]

I believe these bushings don't need oiling
