Was trying to repair a 5yo UK brand router for a friend, only one of the two parts needed available and that was over £100, he had to replace and bought a German router table as replacement parts available. Also had to try and get brushes for a 110V Kango not available..... Have to love the EU for making parts available for longer.......
I've taken to treating any caps working at mains voltage in appliances, tools and equipment as timed service replacement. Reason beimg that sooner or later they WILL fail, usually with results as seen here and worse. So replace them on a time basis before they have a chance to spoil your day. One of the worst offenders are start and run caps on air compressors. If these fail, or even change value, they can easily take the motor out, or even cause a fire! Equipment manufacturers select components on price, so it's a sound bet that the caps used will be cr4p quality. For start and run caps I use LCR, a British company, their stuff is excellent. Anything over 5 years old is imho, time for replacement in these applications. And yes, those bl00dy Rifa things are diabolical! Trickiest recent failure was a 3 terminal switch arc suppressor cap in a 30 year old boiler that went leaky. This was causing an earth leak fault which was tripping the main rcd breaker in the consumer unit. It only happened when the boiler had been running for 30 mins or so and I couldn't find any fault when testing! I didn't even know the cap was there until I saw it by chance when looking at something else, it was so deeply buried! Snipped the little horror out and all was good. The leak only showed up on a high voltage test, at low voltage it tested ok! So s0d the spark interference, it won't be replaced!
EU manufacturers do this most of the time, look at commercial catering equipment and full parts diagrams and schematics are openly available, in the UK it's a lot harder even though most are made from parts sourced in the EU!
@@timballam3675 Well I can imagine that easily for expensive professional stuff but hand tools are not the first thing I'd expect to be designed to last these days. I always try to repair everythinig if I can, often it's just made reaaaally hard by the manufacturers.
Bosch power tools always have the full diagram available and parts available for a long time. Robert Bosch foundation is worth supporting in my opinion over companies that just create profits for shareholders etc
@@sdgelectronics Yes Bosch does still have spares for almost all the products they ever made, though you will find some parts are now expensive as they run out of stocks. But still have a Bosch drill from the 1980's, and an angle grinder as well, and they are still in good order, and spares are still around for them. Other brands are not as easy, the spares might be there, but the price is equal to the price of a new machine, so they get scrapped.
Channeling your inner "The Post Apocalyptic Inventor" TPAI. It's funny, in the upper right hand of my CZcams webpage a TPAI Power Tool repair marathon video from 7 years ago is being recommended next. I have a Bosch demolition reciprocating saw that failed but not as spectacularly. Could be the same thing.
Maybe, but it might eat away at the other electronics quite quickly and then you end up with a bigger repair. It might not be just an interference standards thing.
Hello, does yours get hot? I bought a new one, and it gets hot after 10min of light sanding and smells plastiki? Alu body comes quite hot, never had a sander that got hot not even after 8 hours of sanding. Use sanders daily (mostly festo). For more than 450 euro i expected a much nicer machine. Has been in repair 2 times with Bosch and still gets hot and smells...
Any chance of you reviewing some microscope cameras that are currently available? I was in the market for one with a IMX290 sensor but the ones being sold now are all fake and terrible, so I'm looking for something with a good image / resolution that's still being sold.
They last out the warranty period, and allow it to pass EMC test, so that is all they care. They want you to have it fail just outside warranty so you now buy a new one.
Steve! fixes the power tool and quietly says off camera; Now who's the Bosh! 😂👍 Rifa and Tantalum caps shouldn't exist, made by the Devil. Thankfully a God created Tattoos to cover Scars.
Lol, as you were discussing the exploded parts diagram and the wiring I was thinking to myself maybe you shouldn't trust the diagram too much and go with what is actually wired in the device. Then the other thought occurred when you noticed the discrepancy in the drawing .... maybe the tool was assembled incorrectly from the get go hence the failure? Sorry to be a caster of uncertainty....
The diagram didn't quite make sense as it had all of the motor current going through one of the capacitors in the filter. The original wiring was definitely correct
Diagrams are often incorrect, simply because they are often taken from early versions of the assembly documentation, but are revised with either a different part in production or just because the drawing was done by a totally separate department with no actual tool, just lots of photos to work from, and not ever proofed. Especially electrical parts, where there might be 3 or 4 different suppliers of the part, all made slightly different, and only the one was included in the manual, with perhaps a note about alternates, but no other info. Electrically the same, but often different leadouts and colours, but the same electrically and in most physical dimensions, so it will fit.
It seems like the failure mode of these paper caps is to just explode, and they also seem have an inherently limited lifetime. If only there were another kind of capacitor that used a different material instead of paper that was more reliable and failed in a less violent way. Say, a polymer film. 🤔
3:13 - 'Exploded parts diagram'. Quite fitting. ;)
Love how you can order spare parts just like that for a sander from 2004. They even give you the exploded view of the unit.

Nice to see Czech part description, even though with diacritic error 🙂 Regards from Czech Republic 🙂
Just had this happen with a blender. That being said it was at least 40 years old :)

Thank you for the repair video! 👍
Wow, I did not expect to see proper pictures and parts for stuff like that in this day and age.

Fixed that... like a Bosch

If you are naughty and don't care about the line noise, could you simply leave them out (perhaps bridging some connections)?

I just received another from Eakins, will show it soon
one would think manufacturers learned their lesson about paper caps by at least the 70's
They last out the warranty period, and allow it to pass EMC test, so that is all they care. They want you to have it fail just outside warranty so you now buy a new one.

My first experience in such close contact with such a failure. Lost some arm hair in the process 😂
13A fuse? that seems a bit on the loud side.
Yep......340W!
@@IanScottJohnston 340W protected by a 3kW fuse. What's the starting current of that motor it must have a hell of a torque.
It's 3A or 13A for factory fitted fuses. I guess inrush was a concern enough to avoid the 3A. In Europe though it'd be connected to a 16A schucko
@@TheEmbeddedHobbyist 600W or 2.6A

The cost of the filter and capacitor is higher than the price of a new chinese tool. 🧐
