Ooh! This will be interesting - we have one of these - maybe a handy future reference! (It's very good btw, much better imo than the more expensive premium brand we had that packed up on us 3 times). Paused, made a brew, now kicked back watching another epic Vince challenge. Did you know that due to popular demand, Vince is doing 365 fix-it videos, one each day - between now and Dec 2025? 😜
Oh for the days of Tandys and Maplins. We used to have a fantastic electronics shop locally called Garlands. People used to use them from far and wide. Farnells are great but everything has to be delivered and that takes time. Especially if you’re expecting deliveries via Royal Mail! Excellent watch yet again!
Another fantastic video Vince, thank you very much ❤️ Your hard work & dedication is so admirable & very much appreciated!! Best wishes to you & your family 🙏☺️
Love all of your videos. Not all things can be fixed with what you have on hand. It is the learning experience that really counts. Keep up the great work. Can’t wait for the next series. Maybe you can do a “Cheapest Bentley in the UK” video! Best wishes and a very Merry Christmas from the USA!
Don't worry about not being successful. It is like a Mythbuster once seid. Failure is always an option. So carry on with your videos. I alwasy look forward to the next one. Merry Xmas and a happy new year from Germany.
Great troubleshooting! I assume most of us would be happy to find the faulty triac and resistor, order and replace them and have the same issue again, really good work!
This one was most interesting. When mains blows stuff up it often isn't feasible to fix. Well impressed by your brain surgery soldering on the fine wire. Just FYI, triacs were big in the 70's and 80's as the usual way of switching mains power by low voltage electronics. One of the first things I built back then was a disco light unit (LOL!) that used a triac for each lamp. Now mosfets have taken over that role. Maybe some Chinese factory had a few million in stock they saw a use for!
Good attempt. Guesswork, everything that follows is a result of what I see here. Conventional 4 pole ac induction motor, requires a rotating field (at least two SCRs switched alternately on and off by a micro and possibly a motor controller). Winding resistances typically similar, what failed first difficult to tell. You can short circuit a thermal fuse for very short-term tests, but ideally only try with dim bulb protection etc.
I is a very happy bunny, go to collect my 3 wheel van tomorrow with its fuel system rebuilt and some remedial electrical work all motted up and taxed as of yesterday, the yeller peril rides again in these Dorset roads. The chandelier episode of Only Fools and Horses was actually filmed in this exact part of north Dorset, North Dorset district council were so fed up with fans stealing the opening shot road sign they put in a more modern one lol
Hey Vince you have diagnosed what is wrong, but when it comes to the windings etc then it is a bin job, Well done mate on doing what you can. Never mind next time.
Recently seen several short clips showing people with these finding out the filter was still covered in plastic after having run them for several months or even years. You're likely right on with your assumption of the reason for the failure.
Hi vince, loving the advent repairs, as others have commented I would agree that the manufacturer had installed a North American motor in a UK model, it wouldn't make sense to use l lower voltage motor and design a circuit to run it, triacs are used to control the speed of motors but in this there just beeing used to switch diffrent winding for different speeds thay are also used in dimmer light switches. 👍👍
Interesting, I have the exact same one in black. I’ve had it for quite a while and just changed the filter this morning. The top led turns red when it’s time to change the filter. Now on to watch the video. Good luck. Adding on: you mentioned about not taking the wrapping off of the filter when new. It’s VERY VERY easy to do that.
Intresting how after so many years of doing this we come across a new component again. Now I need to Google how a triak work when it is not blowing up for entertaining purposes 😅. Thank you just a few more days ❤
Stick a 12V fan in it and you have a pretty decent air filter, I have an almost identical one to this but with an external power supply and a 12v fan. Works extremely well although the essential oil feature is not very effective.
Hi Vince, A TRIAC (Triode for Alternating Current) is a three-terminal semiconductor device that can control the flow of electrical power in an alternating current (AC) circuit. It is widely used in applications such as light dimmers, motor speed controls, and heaters because it can switch and control AC signals effectively. so it is like a transistor but for AC ;-) Ignition! 🔥
6:07mins into video - the capacitor is the kick start on the first phase of the AC motor. If it was a DC motor this capacitor would probably be for noise suppression. 22:21 mins into video - the resistor could be smaller, it's only feeding the gate of the triac. The gate current would be no more than 1 amp at 5v giving 5 watts. So a 470 Ohm resistor at 5v gives a current of 10 mA which is 500 mWatts. If your smaller resistors are rated around 500mW they would be up to the job. The voltage and current determine the power and the resistance limits the current, the larger value in Ohms - the less current can flow, the lower the power requirement. 40:32 mins into video - yes you need all windings to work on an AC motor. There are many different types of single phase and split phase AC motors. Resistances of windings will vary on the rating and type of motor. If you have a starter winding and a main winding these will read differently. The best way to tell if your motor windings are right is to just strip down another working identical unit and read the motor windings.
Hey Vince , just wanted to wish you and all your family Merry Christmas and a happy new year. Have a good one bud 👍🏻. Ps don’t forget to show how long the hedge trimmer lasts 😂
Reminds me of those devices where people used them for a long time without realizing they came with the filters inside wrapped in plastic :D They only found out after someone told them on tiktok
Seeing that mess of copper strands has convinced me that I would never want one of these machines and I suspect a strand became touched to something and it backfed mains into the motor, very sloppy and corners cut when a section of fireproof sheath over the strands seems almost essential :( But hey, you now got a reserve of ultra fine enamelled wire so not all bad news. One thing I am doing now is when I can't fix something I harvest good components and with a bit of masking tape or a write on baggie I sort them for use down the line, even things like transformers are uber useful.
Wow. They started building motors similar to certain high end audio components. The PCB and the housing are a bit of a let down but we can still see the overall regress😂
I seem to remember they stay on when triggered until the AC wave reaches the next zero crossing point (twice the mains frequency). The power can be controlled by varying the delay before it turns on in each half wave cycle.
Do you have any idea how much your chanel influences the things I want to buy. I mean you are not the only one, but I just got a Bench PSU and Video Microscope (my second) for Xmas. I've also got Silicon Matts and USB Testers based off what I've seen you use. Anywho, in the vid you just opened your Ferrules and Crimper set which got me Typing. I bought my Set years ago when I got my 3D Printer and it looks identical, except your Crimper does 6 and mine only does 4.
Magnet wire (I call it PEI wire) of this size is a nightmare to work with. I know you can get types which you can solder directly to it ( the heat melts the insulation) otherwise you have to scrape away the enamel insulation.
They are 100% producing them for multiple voltages in the same factory and looks like this one ended up with the wrong motor. Must be that since there is nothing on the board that could step the voltage down.
@@seanwilson7740that thing is a capacitor for starting, you can find them in almost all larger table fans, only ones that dont have it are realy small models with shaded pole motors.
I wonder if the manufacturer installed the wrong motor in this unit, such as one meant for here in the states? That would explain why it instantly shorted out and blew the triac and resistor due to overvoltage of the motor. A bit more plausible than the bag getting through that grating and stopping the motor, especially since the same fault occurred with no bag in it.
I think maybe a test at the motor connector; figure out the common, then hit it with 110v(variac?), or just go for broke and hit it with 240v with jumper, no board, for either a run, or an epic POOF 🙂 I, like everyone, will be gutted when the marathon ends.
If you want to test a winding use your ESR meter it uses high frequency. So the ohms on a shorted coil reads low ohms but a good winding reads high or open. A triac is either on or off, if it is on it passes all current. until the frequency goes negative, if that does not happen the thing blows up. The thing is chances are your IC driver could be faulty
Nice welding sound effect when it went boom :D Seems my broadband modem power supply (separate unit) has gone faulty, intermittently doesn't start when it's connected to the modem, just blinking led lights in the psu and the modem. It stays on if I manage to "trick" the psu start so the led doesn't blink anymore, and then connect it to the modem. Visited the local dealer who sold it to me, asking if they have new power supply units as a spare part, but no they don't. As it's still under warranty, they'll replace the entire modem and power supply with new ones, even it looks like the modem is ok, only the psu is somehow faulty. This happened even before with my Sony boombox, only the cd player went faulty, but they didn't repair it, they just replaced the entire device with new one for warranty. Granted, replacing only the cd player might be not economically viable as there would be labour costs, but external power supply would be very easy to replace. A bit wasteful to probably destroy the modem, fully working, only about a year old, just because external power supply went faulty and warranty rules are what they are.
MMV, sorry, are in the UK or Australia? 🤔 Is that air purifier for a small area? Are the triacs of poor quality? The motor has US voltage specs? Huh?? Wonder if the motor is the incorrect type!!
There's a couple of fairly heavy duty resistors on that board. I suspect they're doing a bridge from 220 v to 110v. Unless you're using an iron core the difference between 60Hz and 50 Hz is negligible.
Resistors would get way too hot and it would be too ineficient, it makes sense in stuff like heaters that alredy pruduce heat but not in this. Must be the wrong motor from the factory, that is why it blew
@ No. They’re designed for power and to handle heat. They’re a cheap solution and often used. Look at them up close on the video. We call it a stiff voltage source.
Seems you’re right and the practice is now banned but it used to be quite common and I’m old. Can’t figure why they have such heavy duty resistors on the board.
@@taxidudeThese resistors look like maybe 3w resistors, not uncomon to see in stuff like this, if they were dropping resistors for that motor they would need to be large square creamic resistors. That motor is probably no less than 30w so resistors would also need to drop 30w to half the voltage.
Whilst I don't know about if this particular motor would need all 4 windings to work what I do know is that you should never ever short out a triac unless you want to create more problems! The fact that you have a 110v ac motor in there should tell you why you shouldnt do that and give some idea as to what the triac's are doing! I think more likely the Triac failed and put the full 240v into the motor which then blew the motor.
hey Vince. I have an idea, when you make your next Advent calendar video you can make it a premiere. That way, we can talk about what we think is wrong and talk throughout the process of the video. Plus, the duration of the video won't give it away. How does that sound?
That would increase audience engagement, which would please the algorithm monster. Plus, I could talk with people and pretend I have friends for 48.32 minutes. That'd be a win\win situation. PS: don't tell anyone that I have no friends. The only downside I can think of, is (with the troll-heavy climate of TH-cam) a moderator is generally desirable, to prevent scammers from trying to sell their stock photos of weird asses, and to prevent whatever else it is that trolls do. A moderator is probably very necessary, because as soon as channels get a certain size, then people with tiny weiners will come onto an open chat, and start being dick-ish.
I bet you they fitted the wrong motor in the factory, they fitted a 120v motor insted of 240v one, that is why it has burned out, It probably worked for a little bit until it heated up and melted all the wires creating a short.
I think its a 3 phase motor. You need all 3 triacs. The speed is controlled by the switching of the triacs in sequence. Have a look at RC motors that use ESC's to control them.
Still a satisfying video, even if the repair wasn't successful. Explosions are always acceptable. Does have me wondering though, if there was no step-down circuitry in that device, perhaps it was a manufacturing error, and the wrong motor was fitted to it?
That looks like the airflow was cut off to that fan...without it it draws more amps which makes more heat. The fan blades were fighting for air basically makes the motor work really hard... Therefore overheating.
FILTER MODIFICATION Instead of getting a new filter hoover out the old one then get the activated filter foam stuff used in cooker hoods and line the inside or outside of the old filter.The 2000 is a countdown timer and fitting a new filter will usually reset it. Some of these units spare filters were never available. I think one triac is shunting the capacitor which is in series with the motor for low speed. All motor coils wired in series for 240 two in parallel for 110 . The cap drops the speed. Put a computer fan in.
technically it is fixable, if you rewound that winding with new enamled wire, though you would need to remove it all and count the windings to get it somewhere near the corrrect turns
Love how Vince isn’t afraid of any repair. “Today, we have a Johnson-class Nuclear Submarine that’s showing no power. Let’s get it on the bench, and see if it’s a lack of plutonium or, something else”. ❤️❤️❤️
Think that would be one for the yellow mat, then.

In lack of fresh air in your environment, I guess there is some cleaning to be done.
A triac can control speed by being switched on and off rapidly as the AC wave is rising
I seem to remember they stay on when triggered until the AC wave reaches the next zero crossing point (twice the mains frequency). The power can be controlled by varying the delay before it turns on in each half wave cycle.

@ No. They’re designed for power and to handle heat. They’re a cheap solution and often used. Look at them up close on the video. We call it a stiff voltage source.
Seems you’re right and the practice is now banned but it used to be quite common and I’m old. Can’t figure why they have such heavy duty resistors on the board.
@@taxidudeThese resistors look like maybe 3w resistors, not uncomon to see in stuff like this, if they were dropping resistors for that motor they would need to be large square creamic resistors.
That motor is probably no less than 30w so resistors would also need to drop 30w to half the voltage.
were blue leds either side of motor rotor a clue to power ?
Whilst I don't know about if this particular motor would need all 4 windings to work what I do know is that you should never ever short out a triac unless you want to create more problems! The fact that you have a 110v ac motor in there should tell you why you shouldnt do that and give some idea as to what the triac's are doing! I think more likely the Triac failed and put the full 240v into the motor which then blew the motor.
Thanks Simon👍
good try anyway. I'd be looking to see if the bearing from the motor would fit your motor from a few days ago
hey Vince. I have an idea, when you make your next Advent calendar video you can make it a premiere. That way, we can talk about what we think is wrong and talk throughout the process of the video. Plus, the duration of the video won't give it away. How does that sound?
That would increase audience engagement, which would please the algorithm monster.
Plus, I could talk with people and pretend I have friends for 48.32 minutes.
That'd be a win\win situation.
PS: don't tell anyone that I have no friends.
The only downside I can think of, is (with the troll-heavy climate of TH-cam) a moderator is generally desirable, to prevent scammers from trying to sell their stock photos of weird asses, and to prevent whatever else it is that trolls do.
A moderator is probably very necessary, because as soon as channels get a certain size, then people with tiny weiners will come onto an open chat, and start being dick-ish.
@@Boogie_the_cat oh I see it everyday, and you just got a friend (:
I bet you they fitted the wrong motor in the factory, they fitted a 120v motor insted of 240v one, that is why it has burned out, It probably worked for a little bit until it heated up and melted all the wires creating a short.
Thanks DIY👍👍👍👍
I think its a 3 phase motor. You need all 3 triacs. The speed is controlled by the switching of the triacs in sequence. Have a look at RC motors that use ESC's to control them.
Exactly
The only part of this series I don't like is that now we're spoiled and expect a daily video going forward.
Still a satisfying video, even if the repair wasn't successful. Explosions are always acceptable. Does have me wondering though, if there was no step-down circuitry in that device, perhaps it was a manufacturing error, and the wrong motor was fitted to it?
Would such an issue be out of the factory?
The sound of that component exploding... Waw... I guess I'm not used to hearing high voltage stuff breaking...
That looks like the airflow was cut off to that fan...without it it draws more amps which makes more heat. The fan blades were fighting for air basically makes the motor work really hard... Therefore overheating.
The plastic bag probably did not get sucked through the filter. It got left on though cutting off air flow.
I'm with you, I don't think anyone else has mentioned that yet. More realistic than sucking the bag up. Good call 💪💪💪😎
cant win them all, but we all learnt something
FILTER MODIFICATION Instead of getting a new filter hoover out the old one then get the activated filter foam stuff used in cooker hoods and line the inside or outside of the old filter.The 2000 is a countdown timer and fitting a new filter will usually reset it. Some of these units spare filters were never available. I think one triac is shunting the capacitor which is in series with the motor for low speed. All motor coils wired in series for 240 two in parallel for 110 . The cap drops the speed. Put a computer fan in.
technically it is fixable, if you rewound that winding with new enamled wire, though you would need to remove it all and count the windings to get it somewhere near the corrrect turns
We finally have a lil bang, yay,
Not reached that part yet 👍
What power is your eye loop please vince
Sorry Spike, I'm not sure. It came with a joblot of watches 👍
"It's going to be something simple" I see the video is 49 minutes. Hmm. Maybe not so simple :-)))) SCTV - They blowed up really good!
It gets complicated
What every happened to the silver shadow
So, the fanny is a no fix then?😢
