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
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
Thank you. Nearly ALL my learning is from the UA-cam 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😎
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
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.
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 .
@@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.
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.
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
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!
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
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.
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.
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😊
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.
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
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.
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.
Mine was because the fans were scraping along the top, I thought it was the actual element it’s self but once I gave the fan blades a slight bend (away) from the top, she came right and has gone back to normal ever since 👌
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
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!
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.
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.
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.
That particular 3in1 oil you used isnt for high speed bearings but for hinges and stuff. You should use 3in1 quarter horse power oil. It comes in a blue and white bottle and is made for bearings.
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 😆
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
I have a Power XL Pro 8 qt air fryer that makes a soft reattle sound for a few minutes before the unit heats up. I wonder if the play in the motor is done on purpose to make up for metal expansion?
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
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.
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.
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.
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 ?
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 😆
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 🤔
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
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
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.
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?
Hi Vince, those small brass looking bearings that support the motor shaft are oil lite bearings they are made from sintered powder of different materials, copper making up most of the mass of the bearing material, here's a quote from a manufacturer of such bearings, 'using powder metallurgy so that tiny pores are present in the bearings. The pores are then vacuum impregnated with an oil to improve the material's bearing ability'
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.
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.
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 😂👍👍
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
Is the plastic fan not there to feed the larger fan? I can't imagine it being designed to draw 200+ degree (C) hot air over a plastic fan. But I've seen worse, so nothing would surprise me.
Also, should that white rubber bush maybe at the bottom of the motor? It's not actually doing anything at the top is it? The weight of the fan is going down not up. I think you're fix was the same as moving the bush to the bottom. Sounds much better now you've worked on it. Nice 🙂
Just curious, do you own a 3D printer ? I'd think a 3D printer could help you fix some items, like if a washer is missing someplace, or some other item.
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.
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.
ok one fan is to cool the motor the second one is to cook the food if they heat didnt leave the air fryer it would get trapped casuing the food to cook to fast and burn and casue damage to the air fryer its self just like a car gets hot in use it has fans to stop it from over heating and if its warm in the summer and you want to use the air fryer i dont see how its any different from useing a normal oven becasue that all so pushs hot air out the back to keep the oven ventilated just like the toaster and tumble dryer anything that gets hot will warm the air around it but simple job open the windows turn the fan on
I think the nylon rings have been installed on the wrong side of the motor. The motor wants to press down due to gravity, there isn't any force pushing it up. Even in operation the fan won't produce enough force to lift the rotor. Why didn't you just move the entire nylon ring assembly to the bottom? That would have packed it out sufficiently, right?

I assume he is talking about food poisoning here so:

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.
You know you are right!
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

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.
Nicely done vince !!
Good job there, mate.👍👍
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?
Fan ovens have a cooling fan as well as a heat circulating fan.
8:38 to stop heat from resistance to motor.
Love your video's the coffee machine one the other week was excellent 😅
Maybe you may use fibre washer and add more to reduce the stator coil clearance between Bush bearings.
The same type of motor used in old BSR decks. An induction motor.
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

You may of been able to slide one of Your spiral gears straight on if one is big enough ⚙️
In the states we call the grey plastic item you cut up to make a bushing, 'Plastic Anchors'.
that's the same motor as my space heater. makes sense, it's loud too.
Sounds like a brick in a tumble dryer 😂

Still not right, but much better.

We have a double Ninja airfryer, and the heat coming off it is minimal.
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.
ok one fan is to cool the motor the second one is to cook the food if they heat didnt leave the air fryer it would get trapped casuing the food to cook to fast and burn and casue damage to the air fryer its self just like a car gets hot in use it has fans to stop it from over heating and if its warm in the summer and you want to use the air fryer i dont see how its any different from useing a normal oven becasue that all so pushs hot air out the back to keep the oven ventilated just like the toaster and tumble dryer anything that gets hot will warm the air around it but simple job open the windows turn the fan on
I think the nylon rings have been installed on the wrong side of the motor. The motor wants to press down due to gravity, there isn't any force pushing it up. Even in operation the fan won't produce enough force to lift the rotor. Why didn't you just move the entire nylon ring assembly to the bottom? That would have packed it out sufficiently, right?
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,
Nice
I believe these bushings don't need oiling
