How did you learn electronics? What was your job to learn so much? Did you go to university and what did you study? Loved your explanation. Very simple and easy to understand, actually made sense without a load of waffle like some KZbinrs.

[@BuyitFixit]

Thanks 👍A lot of stuff was just experimenting and messing about with stuff from when I was a kid. I used to apply voltages to things like capacitors (the wrong way round) and watch them go pop! When I was a little bit older I started messing about with some old PCB's that I found that were from old space invader types games and figured out how to wire them up in my bedroom, and then ended up working in amusement arcades fixing / rebuilding / converting arcade machines back in the late 80's and early 90's. Used to fix TV's for friends and family, and picked up tricks and tips from other techs. No formal training or anything, I just like to figure things out and always want to know how things work.. I've got an inquisitive mind!

[@FreeWhilly734]

@@BuyitFixit very cool thanks for the reply. I repair printers but have always pondered when looking at the circuit boards what's happening. Watching your videos has helped me massively fill in the blanks. I wish I did electronics much sooner as I'm the same as you if it breaks the first thing I do is try and work out why. Very entertaining videos 👍. It's a skill you need these days as half the stuff I buy from Lidl come with manufacturing faults 🤣.

[@서원파-v3w]

I watched your lengthy repairs with great interest. It was a lot of hard work and it was fun. If I have an electronic product, I watch disassembly and repair videos eagerly. It's a habit I have since I have free time after retirement. Because repair is a pleasure. It will last as long as my eyesight can handle it. In most cases, semiconductors and circuit patterns are barely understood. I replace that part, and I fix the rest myself. Your video will be helpful for my Dyson fan. thank you~

The nylon sprockets are suitably robust (probably), you can't design against every possible kind of abuse.

[@BM-jy6cb]

I have a 16 inch desk fan. It has no circuit board, a single shaded pole motor with a single coil. It has 3 speeds and oscillation control. It is over 10 years old, has been subject to all the usual knocks and bumps. It is usually on over 12 hours a day in the summer. It is whisper-quiet, works perfectly and the only maintenance I've had to do is give the cage and fan blades a wash every now and again. It cost £15 at Sainsbury's. The only thing it doesn't have is a Dyson £500 price tag dangling off it!

[@BuyitFixit]

Agree, a lot less complicated, more reliable, and cheaper too! One of the best engineered products I've worked on was the kitchen aid mixer I looked at (video on here) it's 36 years old and like brand new still inside. I serviced it all and I'm sure it will last another 36 years..

this is the most comprehensive repair video of the dyson fan ever! Question: Would removing c51 capacitor solve the oscillating issue? I was thinking if its possible to add a physical switch on the wires to the oscillating motor solve the issue too? Im terrible at soldering!

[@BuyitFixit]

Thanks Zal👍I'm not sure what you mean by R86 capacitor, as R would mean resistor C would be capacitor. You could add a switch if you desired but testing the capacitor I removed and if it's shorted, just removing it by cutting it in half or such would also work.

[@scaleartsg]

@@BuyitFixitsorry i meant the c51 capacitor. If that capacitor is the only one thats causing the problem, removing it wont be much of an issue! i hope my circuit board is the same as yours!

[@ToumalRakesh]

I got a xiaomi fan that has large sound-optimized fanblades which has more airflow than these things at a much lower noise level. Oh and the build quality is really fantastic, unlike the plastic tat that is Dyson. I wish they'd up their build quality but alas, nearly all of their products have either shoddy plastic cases that break in the worst ways (cordless vacuums have the power switch in the battery, and a long flimsy plastic piece goes from the trigger to the battery switch, their hairdrier is made of extremely cheap and brittle plastic, etc) or have weird circuitry that's prone to fail, as you showed.

[@BuyitFixit]

Thanks 👍 I might have a look at those fans you mentioned.

[@NicksStuff]

22:58 In the datasheet of the MOC3083M, I couldn't find a max current across the main terminals. The peak non-repetitive surge current in 1 A and the holding current 0.5 mA but I couldn't find the max continuous current . You say it's 100 mA, do you remember how they call it? Or if it was in a table or graph?

[@BuyitFixit]

I'm pretty sure I saw it in the datasheet, but there might be a few different sheets from different manufacturers. It was a while back, but I do remember it saying that it shouldn't be used to drive loads directly.

Heya,1 more great long vlog loved it

[@ralphj4012]

Well done. Personally, I would replace / refit the triac snubber capacitor (and check it's voltage rating).

[@BuyitFixit]

Thanks Ralph! I wasn't sure on the value of the capacitor as there's no schematic. I guess it would be a quite low capacity and voltage higher than mains voltage.

[@ralphj4012]

@@BuyitFixit Generally, yes, a low value. There's a ton of online info re selecting values, but you can waste the rest of your life trying to fully understand the maths.

[@pramodwick]

I think that snubber network is to relief the stress on the TRIAC. Without it that MOC may fail sooner or later.

[@BuyitFixit]

Yeah totally agree. I guess for how often you actually switch the oscillating on and off though it may well last as long as the rest of it.

[@pramodwick]

@@BuyitFixit I think it totally depends on AC mains frequency. If it is 60Hz, there are 120 zero crossings per second. So the snubber absorb 120 stress occasions per second. That is one of the reasons that cap to fail. As a suggestion you can replace one of that 0 ohm resistor with a 10 ohm one. So it smoothen the RC time constant.

[@gadgetmind]

It's a triac driver as it's a driver that contains a triac, as shown in schematic in datasheet. It's also got zero crossing detect, which is a nice touch.

[@BuyitFixit]

Yes, triac driver which does contain a small triac👍 One one of the datasheets (can't remember which manufacturer but same part number) it specifically stated that the device itself should not be used to drive a load directly and an external triac should be used.

[@gadgetmind]

@@BuyitFixit It depends on load as it doesn't have much grunt.

[@dan19evans]

Mine has an oscillation fault, but not quite the same. It doesn't permanently oscillate, but once you turn the oscillation on, you can't turn it off again. It'll also randomly start oscillating on its own while the fan isn't running. Which circuit component is the most likely cause of this?

[@BuyitFixit]

@@dan19evans I'd think the triac in the optocoupler had probably gone faulty and is latching on.

You know the sound when you first started and I kind of hear it when you are showing it at the end. Like the rubbing sound? I have that but on a higher level to the point where the motor cuts out because of the force against it. Can figure it out. Not sure if the fan is out of balance or something. Not sure.

[@BuyitFixit]

I'd check the fan blades for debris or damage, possibly bearings?

[@alexw6987]

@@BuyitFixit Can you pin this reply because I think it applies to everyone when taking apart their fan and I found my solution.

[@alexw6987]

When you are done cleaning and maintaining your fan, make sure all 4 torx bits that attaches to the fan housing are tight, not over tight but tight with a screwdriver or ratchet. If not the fan blades with rub with the fan housing causing friction and not great sounds and error codes. Also make sure the longer torx bits are tight as they also hold the fan housing in place also and I tightened them a bit at a time in a cross cross pattern to keep even distribution and balance. Hope this helped.

Hello, I'd really appreciate any guidance. I've got to the main PCB and when removed there is a burn mark on the bace from R66. checked F1 that's also gone. when would be your next more? thank you for your time and grate videos, I'm new to your channel, but have been working my way though your repairs. from Scott

[@thetraindriver01]

Really nice fix Mick, just 2 observations if I may... why did you not replace the shorted cap? Was it that you just couldn't find / have a repladement one as if it was a decoupling cap it would be needed, wouldn't it? and the second observation... that Andrex "Wind Sock" made me laugh out loud when I saw it fluttering away at the end there. Absolutely apt use of the toilet roll, very spot on and very funny too, it made me chuckle quite a bit 👍😂😂😂😂😂😂

[@BuyitFixit]

Thanks 😂😂😂😂 I was just thinking how can I show the audience it working. I was unsure on the cap as I think it needed to be an X rated one as it has mains supply across it. I didn't have any so I just thought I'd remove it. My thinking was it's not like you keep switching the oscillation motor on and off every few minutes. You probably just either have it on or off.

[@medifarahi6953]

Great work. My board appears to be slightly different. I can't find R86. I tried to remove the one next to the U1, which is R35, and it's still oscillating when plugged in. Thanks in advance for your reply

[@BuyitFixit]

It's not a resistor you should be removing it's a capacitor! Check the small capacitors around that are to see if any are shorted or have a very low reading

[@medifarahi6953]

@Buy it Fix it thank you The only capacitor near it is the big blue one, which is the v2. Could it be that?

OK, so I finally managed to find a circlip plier that would work, and also had family away so I got some time to work on it. It's a Dyson DP01 with the oscillating when plugged in issue. So I imagine it's also a failed capacitor for the same reason, and removing it and/or replacing it (with say 0.1 uF) should help. I've stripped down to the board, but am not sure which capacitors to replace. I don't see a C51. Is there a way I could post the images (e.g. to imgur or email etc.) and link them here so you might be able to take a quick look? Have front and back photos of the bare board.

[@mechanoid5739]

You can see why the oscillation motor got destroyed, If you look at the top left hand part of the fan body at timestamp 0:43, you can see where the body has been grinding against something while it was oscillating. Probably overloaded the gears and stripped them.

[@jayfowler4747]

Why was the fan melted to the housing at the beginning.... and what was the white stripe on it... as you said someone had been in already and glued that fan that which eventually melted to the housing and hence you thought it was siezed...

I suspect the air intakes might have gotten blocked causing poor airflow and causing the motor to overheat and melt.

Hi, I still have a problem with this fan.The fan noise is very loud.Wondering can the noise be eliminated by changing a new motor?

[@BuyitFixit]

I'd first disassemble it and see if there is any debris clogging the motor or fan (you'd need to do this anyway to change the motor) if it's not that then the bearings in the motor could have failed which would also make it noisy. Hope that helps 👍

[@tanwilson1343]

One more question. You actually applied super glue on the contact between the nut and the fan top,is it really necessary?

[@BuyitFixit]

The original had some loctite on it and I didn't have any at the time so used what I had. The manufacturers thought it was needed so I just followed suit.

[@狂竹]

Just got F2 code of Am07 fan. There bottom motor seems ok , but the wind motor can not move. It is motor problem or pcb control problem? Thanks

Are you sure it's safe to just remove the capacitor for the oscillation motor? I have the same issue and will remove it as well but don't want it to become a fire hazard if I do? If not can you tell me what the capacitor is to replace it?

[@BuyitFixit]

It wouldn't cause a fire. I don't know the exact value as there are no schematics and no markings on it, although you might be able to work it out from similar applications. It is there to protect the triac driver from spikes, so worst that could happen is that IC could eventually fail and the motor would oscillate by itself like what it is doing now.

Unfortunately not. But I just did a quick search on the wattage on the AM07 and it's 65w. Assuming you are in the uk and we use 240v that would be 65/240=0.27Amps so I'd think a 1A fuse perhaps? I just checked in the video and on the schematic I drew on this fan, I wrote the value see 28:35 and it's 1.6A so I think it would be around the same. I would check for shorts before replacing the fuse as generally fuses blow for a reason.

Is there a specific fan motor to replace or can I replace with any Dyson motor ? Your reply is appreciated.

[@BuyitFixit]

It's a specific motor. Check the video description. I put all the information on the motor I bought in there :)

Dear sir I have the same one problem is cold fan works but the heat at does not please help

[@BuyitFixit]

What happens when you try the heat setting? an error? nothing? Does the fan still spin but blow cold?

[@robelemagnu5069]

thank you sir for replying back when on cold it works fine but when it goes from 0 to 1 as from cold to hot it osilates for a while without any air but then it stops and shows an error code displayed e8

[@BuyitFixit]

I've not had that fault before I did try a search on the internet but didn't find a lot. The fact that it works ok on cold, I'd think there's something possibly up with the temperature sensor, or it could be the small board that controls the heater or the heater itself. Might be worth cleaning it all out first, see if that makes and difference, and check the fan inside moves freely still just in case it's something to do with airflow.

[@robelemagnu5069]

⁠ok boss I have opened it movement is good but I don’t know about the temperature sensor or when you say the heater itself what do you mean sir sorry about my ignorance thanks

[@BuyitFixit]

Sorry for the late reply, I only just noticed it. There should be a little black thing on a wire (that's the temperature sensor). I'd just try cleaning everything first, and check that the motor spins freely.

[@heffasponge3656]

Wondering if anyone fixed a DP01 that oscillates when off using the same method? Perhaps identified the equivalent capacitor? Hoping someone has done it already before taking the plunge.

@@BuyitFixit i just now got it apart. no error or f code. it says number 6 as its the fan speed ive had it. 6 displays for a sec or 2 then shuts off. but if i hurry to hit the ocilate button before the 2 sec. it will start to oscilate then shuts down. (fan blade doesnt turn on tho). ive taken the pcb out but havent tested electrical. was also thinkin maybe the fan blade might be stuck? was thinkin if theres a sensor that might be blocked or playing up but i cant seem to google if it has one. am11 model. i literally just bought this fan used in working condition from a neighbor not even a week ago lol. to me $50 was a steal. maybe this is why he sold it. but if it is why, why isnt it working intermittently.

@@BuyitFixit thats what i was figuring. ok so ive found the issue. it isnt the pcb. gotten the motor out. fans free but was sticky. i kept the fan apart but plugged the connections in and tried it. turn fan on it shuts off again. i spun the blade while turning it on and it works again. turned off. it turns on now without my help to finger the fan blade to spin. i think ill dab some 3in1 oil on the bearings and blow some dust out. i dont think its that though, it might just be the motor having a bad rotor vane. so i guess if it does this again ill have to source a motor. that was a quick reply man

I’ve watched My Mate Vince try to fix his Dyson I don’t think it’s fixed “completely, it has recurring issues.” I like watching your videos and I’m a lady…I find electronic fixes interesting 😅. Although, I can’t do any fix’s 😂😂😂.

[@BuyitFixit]

It was actually Vince that inspired me to start doing fixes on KZbin. It was after watching him fix a Milwaukee radio about 2 years ago, and I thought I'd buy one to fix for myself.. Then thought.. Hmmm I could do a video on it too! I had already uploaded fixing a Samsung Eco-bubble a few years before that, and never really thought much more about it as I've always fixed stuff, just not done many videos on it 😂😂👍

[@norbertsmallegange6331]

Is that a silent fan??

[@BuyitFixit]

I guess it quieter than a regular fan, but I'd say it's far from silent.

[@Gengh13]

I would have replaced that capacitor with a 0.1-10nf one and replace the 0 ohm resistors with a low value 10-100 ohms so the snubber works to avoid spurious triggers of the optoTRIAC(with AC line spikes) and the resistors reduce stress on the capacitor so it doesn't fail again.

[@BuyitFixit]

Thanks for the advice 👍

[@heffasponge3656]

Would replacing the 0 ohm resistor with a 10-100 ohm resistor mean the fan will be consuming power when plugged into AC, but turned off?

[@TheDjProgress]

Dyson quoted me £100 to fix the oscillation issue, fair price?

[@BuyitFixit]

Depends of you're happy paying it. The cost of the replacement part (I just removed it) would be around 10p.

[@TheDjProgress]

@@BuyitFixit yikes! Best i get my screwdriver out then 😂 thanks for the reply

[@BuyitFixit]

No problem 🙂

[@TheDjProgress]

@@BuyitFixitis the shorted capacitor a process of elimination or would it be the same one as on your board? I’m guessing the boards are generic, my fan is the am06

[@BuyitFixit]

@@TheDjProgress I think the boards are slightly different but the capacitor it in roughly the same place. If you have a meter just measure it, if it's shorted then that's the one 👍

[@nathanw851]

If the opto-isolator can handle 100mA and the motor is pulling < 20mA I can't see the issue with using it like that. Nice fix... apart from using pliers to tighten a nut, you brute! :)

[@BuyitFixit]

Yes in theory it should handle it, but in the data sheet it says it should not be used to drive a load directly

[@Snooooozel]

Wow, its loud for a fan? 😮

[@BuyitFixit]

Yes, quite powerful when it's on full. We just normally run it at low speed.

[@Snooooozel]

@@BuyitFixit in my bedroom I use a completely silent ceiling fan with a DC motor, was a very good invest

[@mrv4757]

Not that it was the ultimate goal, but was the repair worth it financially? Is the cost of functional fan higher than the price of faulty fan + 2 new motors? Time not counting in as we consider it a pleasure 😊

[@BuyitFixit]

Been a while since I did this one, I think the motors were around £10 and £5, plus the price of the fan and postage works out around £94. I've just looked on Ebay and a used unit ranges from around that to £200 although the odd one has sold for slightly cheaper. My wife was after one and you don't know what parts it needs before it arrives. It may have just needed a small part. It was still fun to do, and hopefully will help others repair theirs.

[@elsaarmstrong-zp6ng]

These nylon gears are a pain in the ass! I have found them in copiers/printers, scanners etc! Some of the better makes have got solenoid clutches so if mechanical load goes over a certain boundary the clutch operates and slips saving the gears from damage! Apparently only silicone grease should lubricant the nylon gears as hydrocarbon

[@BuyitFixit]

Nylon gears seem to fail quite often as you say. Someone gave me a huge office laser printer which had some gears stripped, so I just stripped it for parts. It did have some solenoid clutches too! I know some especially on motor shafts split, or some also split as they age and they deteriorate.

[@markusallport1276]

What I find shocking is the rotating portion of the fan depends on that small pancake motor, almost like it was engineered to fail. No torque control at all, nothing but the tiny gearing inside that motor. It just doesn't make sense to me why they would do this, other than design. No thought of children playing with it, or getting banged around or falling over, animals. For the amount of money they charge for this fan, it's out of line with day to day use and potential abuse. Lets not forget the jet engine noise these generate.

[@BuyitFixit]

Yes, gears just strip as happened in this case 👍

Totally agree, but it gets worse! I also bought a hot and cold version which is a later model. It hasn't got a nice bearing for the swivel now and just a plastic bush and they are using a motor driver chip (which failed catastrophically) instead of the h-bridge and mosfets.
