hey vince, the reason your having a problem with that switch is because the nylon washer is missing between the clip and the arm that control the pressure switch your working with, replace this with a new washer and the issue will not return

Find a couple of washers to take up the slack on the shaft, then stick the retaining pin in. This shouldl keep the little leg straight making sure on it's way up it returns without getting stuck.

I agree a small washer under cotter pin should work.

This is the perfect description of craft mastery. It take a thousand projects to collect the techniques in order to solve and then effectively repair almost anything. Bravo!

Where the pin and crank are pivoted there is an indentation for the spring to sit in. The coil of the spring fit around the shaft pushes out the paper sensing lever. Looking back at 6:43 it looks like this is the spring.

Wow this is perfect. I was just looking for a My Mate VINCE video I hadn't seen to watch when my food gets her in a few minutes. Couldn't have come at a more perfect time. Thanks, Vince!

maybe that wasn't a staple and it was a return spring for the lever

I have used Wago connectors few years now and you are right they are amazing and very useful.

Put a thin washer between the pin and a lever on that switch mechanism, to keep the lever a bit more straight. I think it just getting stuck to the wall.

Looking at the plastic bump above the actuator it had a return spring, as other have said it could have been what you thought was a staple.

Nice job, Vince. You are correct in that the capacitors and inductors on that board are for keeping motor noise out of the AC lines. The thermal cutout switch is probably on the motor itself. They are commonly connected in series at the start of the windings, usually wrapped in heat-resistant fiberglass sheathing and/or kapton tape or similar tubing. Many newer fan motors have a thermal _fuse_ attached in this way, and when they overheat and fail (usually due to hair and dust accumulating around the motor shaft) they just stop working alltogether and get thrown out, as they can be difficult to uncover and replace without destroying the delicate enamel-coated wires used for the windings.

The two Inductors and the capacitor is forming a differential mode EMI filter to avoid the injection of any EMI noise to the line.

Great video 🤗 A small bit of info I learnt a long while ago is that shredder manufacturers say not to oil the cutters. Though they don't say why, I reckon this is because printer paper has a fine coating of clay for sharper prints. I suppose this clay could produce fine dust that would get trapped in the oil. That's why printer paper feels so smooth compared to regular paper.

vince maybe you could use a few small washers on the arm to push it in abit before you put the s clip on

Oh my. I had the same issue with my shredder last week and as it stopped half way through a load and overheated I though I should send it to you. After about 2 hours of it being switched off at the wall it then worked again though. It's funny to see this video now, nice one Vince.

It's a universal motor (can work on AC and DC). You can reverse the direction by turning around EITHER the windings on the stator OR the rotor. The bimetal is attached to the motor.

GG= German Greetings :D The reverse of the motor is pobably just a second spool in the motor. And the overheating is propably just a thermo switch hidden inside the motor..

Reverse is changing the polarity from the anchor windings. 4 wires going into the motor. 2 wires into winding outside, 2 wires into winding anchor.

Those blue "capacitors" a MOVs (Metal Oxide Varistor), typically used for power surges, so that circuit looks like it does some power smoothing and protection. The big yellow thing is a film capacitor (for smoothing) The motor probably has a thermistor inside so when it gets hot it shutdowns the motor.

The motor has an overtemp cutout switch on it that cuts it out if it gets too hot. Also a thin washer would keep the little plastic arm more in line with the groove and should stop it from getting stuck.

Nice fix Vince. Looks a little like the 'push lever (long arm)' could have the end shaved at an angle so it doesnt catch on the guard

We've got the same shredder, with the same problem. I've never got around to fixing it. I might take it apart soon now I remember about it.

Nice fix vince. I’ve binned 2 shredders in the past as well!

I think you were correct way back at the beginning, it is supposed to run on for a second or two so the paper is ejected from the mechanism, this is usually done with a cam on the cutter shaft so the switch would remain pressed in until the cutter had done at least one rotation. Keep on fixing.

After viewing your video, I attempted to fix my own shredder with the same problem and the same design. I'm not what you would call real handy, but I tore into it, cleaned up the mess inside, took some time to put it back together, but it worked like new! And I even had a part left over!!

Could there be a return mechanism on the lever for the button?

Maybe graphite powder as lubricant would work.

@eveangreen1871

Mobin92. Graphite in its make up is carbon which is conductive. That’s why some membrane pads have graphite pads. So it would constantly mess with the switch turning it on and off at random or even completely leaving it on.

The spring inside the switch has stretched. You could fix it by taking 1 winding of the string but you are right if you take to much off. It will no longer click down. The coils and the cap are a suppression filter. The JY472M from what I can find is a safety capacitor. Which is designed to reduce Electromagnetic interference(EMI) and radio frequency interference(RFI) caused by the motor. I can't tell you for sure but at a guess there will be the equivalent of a thermostat on the motor. Which will ping apart when it gets hot and when it cools down it pings back shut.

@zierlyn

Actually, since the spring passes through the contact arm, it pulls the arm down from underneath to make the switch close, and tightening it would make it pull down harder, not stop it from working.

"Across the line" (or X capacitor) means the capacitors can be connected between live and neutral

Jumper weather huh? It HAS been bloody cold recently! Keep up the good work fella!

Adding a small washer on either side of the lever arm, would hold the lever true. The spring is strong enough as long as there is not too much load. hence the 6 sheet maximum.

Hi Vince. Maybe motor got heat protection inside it? Also this white arm looks like it's need to be pushed away from that metal clip on the end. I repair same paper shredder in my company and 100% true about that grease - there is too much of it, everything was covered in paper dust even after one week of use. After couple of cleaning it's ok and amount of grease is perfect.

I have an older version and it is terrible with the paper getting built up between the plastic barriers in the center and it looks like they didn't improve the design at all. Frequently have to take it apart to clear it out.

Cheers for this video mate, I just fixed my shredder because of this and its was my sensor A quick clean and check of connections and now its great. 👌 🙂👍

Is the switch high resistance under load? Bad contacts?

If you haven’t tried baking soda and super glue, now is a good opportunity. You can build up the slot which the lever passes through so that it pushes the tip away from the hole it’s catching on the opposite side.

Hey vince. Would you like a fix a faulty ps3 controller?

Vince , i love these videos..They are oddly satisfying , and i like to do these things myself aswell... You are the proper repair man :)

Interesting. However I would not want to leave that connected for long periods with 240 volts going through a potentially faulty micro switch.

If you look in the paper feed slot, there is the rectangle slot that the arm slots into. The arm is catching on the edge. If you widen the slot, maybe the arm will return easier.

what a relief when finally solved the issue.

What about a small rubber band fixed to the lever on one side and on th other side to the holder of the micro switch?

To me the sound at the end before it quit sounded to me on my setup like Electrical Sparking where the current was jumping directly between contacts in the motor before it could turn again. Would also explain the burn smell.

Yes! A 55 minute video! Thanks!!!!

Vince, look at the end(tip/bottom) of that arm, it hangs up on the little step(groove for the paper)(min. 49). There is a groove in that frame for the arm to move freely. Since the arm is to sloppy, the end is getting stopped on that corner. Use a washer between the arm and cotter pin.

Look at when you poke in there with the exacto knife. minute 49.56.

You can see the thermal cut out on the motor @40:05 its tied to the field windings with black wires going to it also that is a universal motor wich can run on AC orDC and is reviersed by changeing over the output from the field windings to the brushes, there the same type of motors used in corded power tools. The small pcb is an EMI filter the inductors an capactor filter noise from the motor and the resistor across the capactor is to discharge it so you dont get a shock from the plug pins when you unplug it.

Great video Vince and it's lovely to see a everydayish item being fixed. Never had this problem myself but I am very surprised this happened to you.

Nice fix! would not two washers make it more stable and less likely to clogging up? Love your channel always entertaining!

Hi Vince have a Auroa shredder same problem not cutting off

Here in Canada I've seen that microswitch using a variety of applications even in dishwashers and what not. I remember having to replace one in a dishwasher and not really knowing how common they were I bought a replacement one from an appliance store and they way overcharged me. I was wondering if perhaps a homemade washer made of slippery plastic what type used in vinegar or cooking oil containers placed between the sensor arm and not retaining metal clip might have help with the alignment so that it wouldn't fetch upon adjoining protrusions of the actual case? Perhaps a little gooey Grease was also a culprit mixed in with paper fibres just wear that arm is catching up. Well Vince, as I was watching this I was wondering how the Crazy Russian Hacker would fare in this repair video. He's constantly slashing and cutting himself accidentally when he's testing kitchen gadgets. He probably get one of the plasters on his fingers stuck in the shredder, LOL. Or worse... Drop it into his lap while it's plugged in and get sack caught in it Bwahaha As usual I enjoyed this video as I enjoy taking apart stuff if I'm watching videos by myself or if I repair things that were given to me by friends. Have a great day Vince and don't drop that thing on your lap! Well at least don't if it's plugged into the mains

I would use a washer between the arm and the switch

Nice Repair

The circuit with L1 L2 and the yellow capacitor is a mains filter (Seems to be a slight variation of a common-mode filter, which is to take switching noise out of the mains), then the switches are simply switching power to the AC motor, the two blue caps on the motor are just noise suppression capacitors on the motor. The motor will be a universal motor, and they can be quite noisy on the mains with the brushes/commutator. It'll also have a overheat switch, which I suspect might be a bi-metallic strip switch on top at the back of the motor (The black and metal thingy). Your switch is faulty, even though you tested with the meter, it doesn't test it under load. Also I think you may be missing a little spring on the plastic paper detect lever, and that's why the switch struggles to turn it off, probably the internal spring in the switch weakened, and it's not switching off cleanly, and possibly burning the contacts. The yellow and blue caps are special safety capacitors, commonly known as X capacitors and Y capacitors, they are designed to fail in a safe way across the mains, and not short out.

I've got a fellows paper shredder. It too has lost its ability to detect paper being put in it and is on auto all the time. Just took it apart whilst watching your video and thought I'll have a go! Couldn't find what makes it detect the paper going inside it but I regreased all of the gears and it runs smoother now lol

That was a pretty cool fix

Under appreciated video fix!

I have one the same..i bought a new micro switch..all the contacts inside the switch were burnt and it did not connect properly(when i took the switch apart) and it did not return to the off position weak return spring inside the micro switch..the new switch cured it straight away.The switches are real cheap quality on these.

Vince marvelous.

I would shave a chamfer on the lower end furthest away from the pivot where it appears in 2D to be visibly catching on the paper guide slot. Watch the end part of the video again, (when this reoccurs) where you realise the lever is sticking. Enjoy your videos mate!!

Tightening the spring inside the microswitch won't stop it from working. It pulls the contact arm up and down by passing through the middle of the arm from above to below.

A shim might have solved the issue. Or simply file a slight part of the piece that touches the paper. I was getting caught. If you looks back on the video you can see it getting caught

Capacitors are storing electricity, and charges out over time. (Essentially timing devices...) That could be used to keep the motor running for a while. But obviously at decreasing power. The duration is often determined by the amount of resistance in the circuit, that the capacitor has to discharge to... Unless there is some kind of setup to feed it directly from the source while the capacitor has over a certain amount of charge left. Which I don't think it is in this case, as it sounds like its slowing down gradually after the switch is no longer hit.

@Fifury161

That's not whats happening in this circuit - the capacitors in this circuit are there to suppress spikes (EMI) and in conjunction with the inductors to suppress line noise...

It looks the end of arm of the switch is sometimes touching the metal cutting disk or the plastic frame. Probably you can put a washer and the end of the axis near the clip to keep the arm closer to the switch. The arm looks like bent outwards.

Plastic washer on the shaft between the arm and cotter pin.

I would have cleaned up the points inside the switch while it was open, pitting and piling on the points can cause a delay when they get hot. Also agree with the other comments there should be a nylon washer on the lever arm to align it with the groove in the casing.

Have you used lubricant on it? I see it’s not a confetti shredder. I use WD40 on mine.

That motor is an ordinary little universal motor like you get in lots of appliances. They'll run off of AC or DC.

I wasn't happy when it was partially functional, but I am delighted that it's completely knackered - paraphrased.

There is very little electronics in this, there are 3 switches and 6 components. There is no timer circuit. The inductors & yellow capacitor are for line filtering, the blue discs that are across the motor are for noise suppression (to remove EMF spikes). The 3rd switch is the thermal cutout on the motor.

I started laughing so hard at 18:13!

i think regular cleaning of the grease will be better than not, even if that may foul up with paper dust eventually.

I stripped down my parents shredder and the grease that was in the gears was really sticky and taken ages to clean it out it still overheats but goes on longer now

The bottom of the pusher finger is definitely fouling on the case, but only when it moves more to the right (in your video) than it should be. You can see this very clearly as 43:30 ( kzread.info/dash/bejne/aqSmu7Cmebmamco.html ). I think it moves to the right (twists) because either the plastic spindle on which it rides, or the hole in the finger through which the spindle passes, is worn. As others have said, possibly a washer between the finger and the R clip would stop it. Or possibly drill out the hole and insert a plastic bush of the right size.

Excellent job =D I think replacing the microswitch would sort this without the adjustment of that plastic piece! It is not springing back outwards with the same force as a brand new switch! You can get replacement switches identical in size to the one in there btw! I have the exact same Shredder! And incidentally, I got a brand new one here to find a home for that is boxed never used (given to me recently).

I think you are right Chris, by trimming the pusher I have just taken up the weakness in the spring. I should have trimmed the switch plastic bit instead of the pusher which would have done the same thing. Then if the switch was replaced in the future it would be back to the original condition. Thank you :-)

One or more of those blue components attached to the motor may be a PTC resistor. These are components who's resistance varies according to temperature. As the motor heats up, the resistance of the PTC changes, until it reaches the point where the motor is effectively taken out of the circuit. Switching PTCs are highly non-linear, so their resistance suddenly ramp up above a given temperature threshold. If you want to find out more, TDK have some useful examples on their website here: product.tdk.com/info/en/products/protection/temperature/limt-sensor/technote/apn-limt-sensor.html

in fact, the motor has a 3 wires connection, 2 of them are used to receive the 2 wires that we use in 240 v, the capacitor replace the 3rd wire, and it is been feed from one of our 240 v wires, the reverse action happens when we change where the capacitor is connected to the motor

ac motor is reversible with the capacitors causing a phase shift

@jonnymorgan8385

Not that type of motor its a universal moter its is reversed by changing over the output from thr field windings to the brushes.

Vince, allow me to help you out mate. The problem is in the white push button switch box. The return strength of the button has worn away with use. Open the box and see if you can get a pair of needle nose pliers in enough to shorten the spring just a smidgen. This will allow your pusher to FULLy return to allow it to turn off. Moving to top switch helps because you are running it backwards causing the pusher to return to full return and so it is off. Again, the return throw of that button needs to be a tad stronger or/ "prouder". This should fix it next time - good till the motor burns out or you get a new shredder.

How much is the switch for it

Well done mate.

Vince, while you have the shredder working, as well as you can. The OCD in me tells me that shredder is only good for arts and crafts to make streamers or some pasta. What would be an ideal shredder, is a cross cut.

Looks like the lever is gagging up on the spindle because of the angle it’s sitting at, increasing the friction enough to hold it. Interesting. Thank you.

I also thank that yellow component next to the 2 inductors is a rectifier bridge to convert ac to dc which would make sense with the reverse but I could be wrong just my thoughts

This happens to mine, now I know how to fix it.

APU I dropped like even if-n it was some mechanical hiccup that caused the fault rather than some electronic or electrical one..

I have the exact same shredder with the same fault. I just assumed that a little bit of paper was caught in the trigger.

I never click so fast in all my life unless My Mate Vince is in the house. Let's go!

By looking at the footage this which is coming up very slowly end is slowly beginning to cut the connection off which is why the motor sounds like it's struggling is it getting is because it's getting less voltage this which is actually gummed up and it's actually disengaging very slowly

Haven't watched yet, so gonna guess paper sensor, something real simple wich is a shame cos I no you like a challenge...I'm gonna do this on all your great vids, I'm gonna write my guess first...now off to watch it.

Seems to me the pivot for that lever is too sloppy causing binding. I think some tiny washers might reduce the friction at the pivot and prevent it from binding.

Vince the way your motor works is it has phases each wire is one phase. You can switch ANY two wires and the motor goes the opposite way. but if you switch two wires then switch one of those with the third one that was left alone you are back to the same rotation.

normally the automatic setting usually runs the paper shredder for 2-5 seconds after paper has passed through the switch before the shredder switches itself off for the cutters to clear themselves (bad design floor, as the cutters never clean themselves out). I would much rather a near enough instant cutout, because doing a load of shredding will soon give a stinking headache especially if it is going for 2-5 seconds ontop of the paper passing through, and you got a lot to shred. so done yourself a favour by getting rid of that feature.
