- Looking into another fan that didn't work. This one had a blown termal fuse. I also accidentally tore some of the wiring. Not worth
trying to fix this one. I find fans like this in the garbage not infrequently, so I'll wait for a less broken one.

I really appreciate that you published a video of something not working out and explaining why. Too many channels give the impression that everything always goes smoothly and it hard, as a beginner, to progress with that as a standard.
In Electronics School in the first few minutes of the first day my instructor told the class if you expect to troubleshoot and repair, you have to have the courage to open and inspect what ever it is you are trying to repair. You have that kind of gutz! Thankz
For blown thermal fuses:
You don't have to disassemble the motor wiring harness. The run cap is between the neutral/common wire and a split phase ending. One of the capacitor lead is the common after the thermal protection, if it's blown, there is open circuit between one of the cap lead and the common wire, thus any wire from the motor. Cut the common at the harness, install a new thermal fuse between it and the previously identified lead and you are done! Good Luck!
This is 2 years back but could you/someone do/point à video on this.
Posting this video even if the repair failed is super-honest....bravo and ma cha Allah for your nice mentality and your greatness of soul.
Firstly I hand it to you for making videos that people can learn from your mistakes instead of them diving into something that is over their heads lol. No but really, kudos to you for taking the time.
As for finding the thermal fuse, dont try assuming wiring will be certain colors. Companies use what's available. But the first thing I saw when you pulled the motor out was the thermal fuse. I'm not bragging by no means. I've always been mechanically inclined but I'm far from being an expert in electronics. Here's how I knew, I just recently opened up the same fan some days ago. I didn't even know what I was expecting or looking for so I searched online and found out about the thermal fuse. So there I went staring at the motor and its windings until I saw 1 wire that went into a white protective tape and another wire coming back out. That doesn't make sense UNLESS something is between the wires; yes, a thermal fuse. So I only had to cut 1 tie wrap. Also, it's never smart to yank or pull on wiring, especially wiring that thin. Just take your time and stare at it if you have to. Again, I'm not making fun. I've made so many mistakes by rushing in before investigating the situation or by losing my temper. Hey, I'm just keeping it real.
Lastly, you can order thermal fuses online. Don't bypass it by connecting the 2 wires. If the motor gets too hot it will start a fire.
What are the chances, I got home today and found my fan broken. I first thought it was that lube problem that you already made a video about it, but it wasn't. Than I opened my youtube home page and this video was in the 'Recommended' section (I wasn't a subscriber of this 2nd channel at that time). So I watched and tryied to fix mine. And guess what, it was exactly this problem, the termal fuse. I shorted it's two leads and reasselmbled the fan, now it's working fine. Thanks for the video, saved me some bucks. I didn't knew about those termal fuses, can't count how many ventilators thrown away probably because of that.
The only downside is if it overheats, It might cause a fire.
that fan was fixable, I just recently fixed one with exactly the same problem. You might just find a way out not to disasemble the motor wrap by identifying the capacitor cable and the power, then bridge those with a new fuse...or if you definetely decide to unwrap the motor PLEASE DO IT GEN TLY. with the help of a sharp blade, do not pull them apart.
Like any other handyman, we all experience failure. We learn because of it. Thank you for posting this video.
I used to work at a dumpstore here in the Netherlands, I wish I could have showed you the place, especially the garbage area behind the scenes.
It's a goldmine for someone like you.
Interesting in that my oscillating Northern Hydraulic “Hurricane fan” is identical to this fan. At least the motor is identical. The oscillation mechanism is aluminum in mine and since the Chinese don’t waste time with bronze oilite bushings, that’s what locked up. I just got mine apart and decided to look online for some pointers and now I know to look for that thermal fuse. So this video is a win for me. Thanks for posting it.
This is how my every attempt to fix anything always ends!
Roberto Galea same here..every time
agreed.lol
Roberto Galea I'm glad I'm not alone. Almost everything I fix ends up in the trash bin.
@@MrOner07 1123
Let's keep trying until there is nothing worth to fix (?
Love watching you take apart things while you explain it like this 👌🏻
this is exactly how all my fan repair attempts always ended...bout 4-5 fans have already been my victims
Do they use ac for the motor windings? My stupid brain is trying to figure out the schematic, but I keep thinking it's 3 phase ac because that's what I normally work with motor-wise.
@@burtmcgurt3584 it runs off of single phase ac
but will have a special shaped winding or special windings that are only used for a bit to get the motor spinning, matthias already had several videos on it
Wow! a fan serial killer!
Work on them slower and carefully and you shouldn't kill them usually not hard to replace broken components like thermal fuses and put everything back just don't get in a rush and pull on wires. If you need to you can cut wires and re attach them just to make it easier also solder and an iron (soldering iron that is) helps
Some cheaper fans are like this. Better ones have the windings soldered to a PCB and it makes the repair easier
Love it!
"Not worth repairing"
Now you're talking!
Thanks Matthias, you are an inspiration. Even though I haven't got any power tools, when I see your videos I get fired up to go and fix something -- or at least try.
Now this is how I like seeing a video to repair something. Fast speed while taking it apart.
Wish I had known about this separate channel sooner. I had a fan go out with probably the exact same motor. Talk about manufactured obsolescence if they just made those fuses a little more accessible they would be so much easier to repair.
I'm trying to speed up my little DC fan motor by rewinding it with thicker copper wire. Because it's super slow and weak (0.15 amperes), and increasing by 0.45 amperes will make a significant difference (the more current the more force against air resistence). Ok, to the point. I broke 3 fan already in the process. I gave up and now I just buy new one more powerful.
Appreciate the tinkering
I saw the thermostat as soon as you opened it. Sheesh man you have to be patient and observe things before going ape crazy pulling out wires like in Planet of the Apes.
Exactly 👍🏻
And have fixed many of these… this is a stupid ass video…
I always wanted to know where the thermal fuses are on those units. learnt something today.
Tomorrow you can investigate the word "learned"
Well, glad I'm not the only one this happens to. But thanks for letting us know what are the good parts to strip off.
Can the metal plates from the motor be used for anything?
I have never seen a Hewlett-Packard multimeter. Pretty cool.
Still made in China...
Honestly was having the worst day repairs and obstacles driving me insane this just made my day the honest uh oh reaction made me lol
Thanks for the video bro it really helped alot. I managed to fix two fans today
When you know to throw in the wastebasket!!!😁
Always love watching your videos!!!
Thanks
you also have a lovely chunk of copper there. Free money if you have a decent recycle place nearby
+verdatum That much copper isn't even worth the cost of gas driving to a recycling center.
Oh, agreed. But, if you throw it on a pile, it adds up.
+verdatum Yep, I do that with copper I get hold of, even short offcuts go in there. When it's a good few kilos, off to the scrap dealer I go
bonus if you separate the electrical copper and the plumbing copper. You get a premium for proper wire.
Actually some fan motor use aluminum instead of cooper, and I think that motor use aluminum too.
I had a small fan fail. It uses a shaded pole motor. I cut the tape open to expose the windings. Found the thermal fuse. It was tiny, and square. 115 C° . I cut stuff out of the way to get the fuse out. It was open. But I cut the other wires, so I can't fix it. I was just curious if the fuse failed.
The motor spun freely, it had no reason to overheat. It ran, i turned it off. And after doing that 100's of times, it was dead the last time I turned it on. Those fuses can fail spontaneously.
is there a way to know which tiny copper wires on the spools are supposed to go to their corresponding wires?
When he said "I dont have to worry about getting it right" i said he is going to Fu#% up that fan.
Not worth fixing but how about the induction motor without speed control, is that worth saving?
The copper coil is heavy & is worth a lot and should be recycled. Hopefully it will be! Is it ok to use a grease on those bushings? I have a ton of these motors in my household fan collection in India and they are always need lubrication!
Oh well . . . I have a good repair person to take it too.
My brand-new Caterpillar fan stopped working when i accidently unplugged it while it was running. any idea what causesd that? It was also plugged into my modified sine-way inverter if that matters
I can't find a thermal fuse. Can I connect it directly without the fuse???
Don't do it, thermal fuse is a safety device to prevent overheating and potentially a fire.
I used to be a fan, but now I'm an air conditioner
Pareces un cirujano 🧑🏻⚕️, felicitaciones 👌🏻 y saludos desde Cali, Colombia 🇨🇴
Hi Matthias, thanks again for an informative video. Even though the repair mat have been a fail, you and we still learn something from it, right?
Could you have replaced the thermal fuse? I have a ceiling fan that has a light fixture. The light fixture stopped working and found the thermal fuse failed. I would like to replace the fuse but don't know where to get one.
+LXGIK 80 Ebay, electronics suppliers, etc.
I have been searching all over the Internet for someone to get that close to a fan inside as I have. The fan i have is a floor fan more of a high powered one and on the inside the wiring is almost the same as the 1 you ripped into pieces. I was trying not to have them pull it apart as far as you did but I cannot find a fuse in this fan. My son left it running and it was just packed with dirt and when he went to touch it it literally burned him and quit running completely. So I have it all pulled apart in front of me for about a week now and don't want to throw it away. I don't know if there is a fuse inside where those wires are like the ones you pulled apart on your video. Should I pull all them apart or not because will I be able to put them back together? Of course the capacitor is in there that you saved but I don't not now if it needs replaced or not or how to tell. I do not have a electric tester like you have so I don't know if ì can't check anything else without it. I checked the fuse at the end of the plug but it was not clear, it was white with a red line around the center so you could not tell whether it was burnt or not. So right now I am at a stand still mostly because if you would have been able to go a little farther than when you ripped the wires all out I may have been able to see what was inside without ripping it apart. Lol. I guess I will just have to wing it but really don't know what else to do from this point on. Thank you for your video!
I’d have to look at it to advise.
can one still save the motor if some wires have been pulled off?
very difficult, wasn’t worth it for such a cheap motor.
@@matthiasrandomstuff2221 I know but I want to learn. Any way you could instruct me? If it's not too much trouble for you of course.
Lol.... crack handed much! Serious face palm moment when you ripped the wires and then proceeded to rip out the thermal wire! Got a good chuckle out of this video.
Why you pull out the thin wires?
Good to see you also fail sometimes hahaha. I lost count of how many times I had more work to fix something than I would've originally if I wasn't so stupid!
hahaha i love how you broke everything and I still learning a bit
I don't know enough about it to grab hot wires and hope I don't get shocked.. Cool video!
Nice, your so smart you can explain things easily, nice videos. Im gona try your technicques out on my bathroom fan motor, hope I don't die ;-)
What? You mean rewinding a fan motor isn't your favorite past time??
I think I learn more from the repairs that don't work!
Can you test the run capacitor?
Hey Matthias, i have that same kind of electric motor for my homemade fan and the motor easily overheats. So, that maybe the cause of the broken motor
Interesting video, I actually leaned something. Appreciate the high speed too.
While cleaning.....
Fan run without blades for some time.
Now it doesn't work.....
What could be the reason, please help.
Shafting replace and bushing
A good technician is the one that breaks it and remakes it
I was shouting at my screen ! " the thermo fuse is right there ear your fingeer !"
Hi. If you replace the capacitor with the higher one, would the make the fan spin faster? Thank you. God bless, Proverbs 31
It will make the motor stronger. I've tried this experiment. One of my stand fans has a 2.5 uf capacitor, so I replaced it with a 4 uf cap. The motor ended up coming to full speed about 2 times faster.
Ternyata di luar negeri juga ada tukang servis kipas.👍
The motor looks clean like it never been used before probably the owner thought it had power but it didn't had power only low power that's why throw it away?
You broke it, now fix it. Jump out thermal overload and reconnect the wires you yanked apart. Fix it....
I'm getting interested in electrical work so this is very interesting.
watever dude so ther are thermal fuses in fans (i didnt know ) but ive fixed over 20 fans and it was never that fuse. its mostly gunked up or blown cap< and blown cap is very common on a lot of things. (also i just fixed 2 fans right now today ..out the trash ..
You sure have a lot of brawn. It's nice to do an autopsy on dead equipment hoping to bring it back alive. Most times it's a lack of bearing lubrication that is causing the overheating /burn out of the stator coils of the motor. Use the blue can of '3 in one' lubricating oil or any "non-detergent 20-w motor" oil to lubricate the shaft bearings and wadding cup,if any. Lithium grease works, but the oil is best. Some manufacturers use "security screws" to assemble the covers to avoid home repairs. Keep trying for the finesse touch.
I cringed watching this. Luckily all of the fans I find in the garbage have clear reasons why they were thrown out. Burnt motor, cracked plastic pieces, broken oscillator, overall flimsy construction, owner didn't want to clean the fan........yeah. I find lots of fans in the dumpster. I only have one fan that I bought brand new, and it is in my profile picture.
the only thing that makes sense here is the multimeter. idk if youre that nervous or youre new at electronics- small wires solders stuff
IT´S NOT CHOOCHIN'
CCR
when it overheated it probably let the magic smoke out
The fan looks brand new.
You had it all figured out though.
Yeah those windings are delicate I've did the same thing trying to fix my box fan.
That fan is still fixable here in Nigeria, u can't just dispose that new coil because of little mistake
Thank you for great video just found the problem with mine the thermal fuse is blown and is only 5 dollars online
NICE video, but,,, you don't have to disassemble the whole unit to check if motor is dead or broken,,,
you have your multi-tester,,, the easiest way to check the thermal fuse is to use your tester,,,set it on OHMS,,, one probe to #1,2 or 3 button terminal and the other probe to the wire that comes out from the motor connected to the plug,,,, if the reading of your tester is "0.0 or OL (open line)" from the three terminals,,,, then you have a BUSTED ThERMAL FUSE,,,,
right tool for the right use. you destroyed a perfectly good lemon! shame shame.
Heavy handed approach and purpose of this video
I was yelling at the screen telling you where termal fuse was and not to cut into coil . not sure why you couldnt hear me ! 😂😉
Save all the metal. Sort by type and grade, and when you have a sizable amount of each, turn it in for $$. Check the scrap market, so you can pounce on the good times and avoid the bad times.
Electric drivers are amazing for salvaging stuff. good job I didn't have 1 as a child. I would of taken the world apart.lol
the Thermo fuse is broken mathias
Umm, yes... that's what I said. Why repeat it in a comment?
Yes but the thermal fuse overheated at some point, so that was the end of that fan
I hear what you all are saying. However, the thermal fuse is blown.

I wonder what would happen if Matthias and AvE joined forces.
Why you didn't check the capacitor which's responsible for %90 of fan's failure!
Because I already knew it wasn't the cap based on the symptoms
idk anything about electronic work so i just learned something ....
Had to resub your channel. Guess UA-cam decided you didn't need me anymore, I guessed different.
I'm no electrician but whenever I'm measuring mains voltage I always hold both probes in one hand just in case
I can fix this crash without decoding one nail and one second
Anytime I feel down and think I'm not "good enough", I will watch 3:24 . And if that doesn't do the trick, I will watch 3:58.
This video is so painful to watch. Right after he yanked the wires apart I had to rewind to the beginning so it wouldn’t be so painful.
You anti-capitalist! Go buy a new one!
(kidding)
I love this kind of videos. Since i was a kid i disassembled my electric cars to see what's in them. Great video, a lot to learn, cheers!
5:06 'You see this kind of stuff in waste so often', so even if you see it so often does it make it right? Change your thinking man. If everyone is jumping off the cliff so does that mean you should too? Decrease your waste or the day is not far when environment will be lost.
The capacitor, that black thing is probably bad.
if you are in my country,"Philippines".. you can easily buy a replacement motor for that or let the electricians rewire the whole thing for around 200-220 pesos or 5 bucks or 5 US dollars,...then connect it to this thing and its as good as new...you can even earn something from the junk shop as you sell these busted copper coils....
but in our country, it's cheaper to buy a new fan than to hire a professional to spend half an hour on it.
@@matthiasrandomstuff2221 now that's too bad...how I wish i could import those busted fans and fix it and probably earn a lot from it...some people here prefer "imported stuff" regardless if its brand new or not...
If the engine got burned no way fixing❤
Your knowledge is disproportionate to your skill. Liked the video, though. Reminded me of the times I painfully realized there is no "undo" in hardware like in software.
How about a LAW banning companies from putting these stupid fuses in places that can't be fixed. I HATE this society of throwing all shit away into the trash.
It wouldn't help. If it was a replaceable fuse, the fan would still end up in the garbage. Cause first you'd have to figure out and fix why the fuse blew (likely from not spinning due to bearings siezed with old grease), then find a fuse and replace it. Things get thrown with far less things wrong with them. Thank Chinea for that - things are so cheap, it's not worth taking stuff to a repair man who would charge $50 to fix a $20 fan.
@@matthiasrandomstuff2221 It is very amazing how people in west can be so wasteful. That's why everyone should learn to repair basic household appliances so that less garbage is created and you won't end up spending 20 dollars as charges. "Things get thrown with far less things wrong with them", this is the mentality we have to change. Even though the motor may be recycled but it requires resources to recycle and if it ends up in land fill that will only increase the plastic pollution in nature as most of the parts are made up of plastic. No offence, but the attitude you have towards discarding things over repairing shows you are an American which btw is not appreciable.
"Cause first you'd have to figure out and fix why the fuse blew (likely from not spinning due to bearings siezed with old grease), then find a fuse and replace it", this was totally a low cost and effective solution, you knew about the solution and yet you decide to throw it away (I don't know why, may be you were lazy).
Well with that fan that he messup with ,the problem with it is the bushing,thats the cause for the thermol fese to blow ,so he have to know what he have to do
Matthias just man-handling those wires.
Awesome... I usually stop before getting into the motor... taking motors apart is unknown territory for me.
Man you should improve repair skills. I spotted the fuse when u opens the motor case. Just learnt about thermal fuse few minutes back in youtube.
Matthias, i suggested you to use the condensing unit fan assembly for your project because those fans are more powerful and will last longer like the 1996 and 1992 toshiba aircon fans i had
later you should be careful if you remove the fuse if you found a fan from junk
try to make a windmill with the fan blade
haha
thermal fuse in a fan? ?_?
Yes, most motors have thermal fuses.
The motor wire can make a crystal radio...
You touch the wire with live current from the socket wall and you not get shocked! ?
gets the wire strippers after he breaks it. lol
You were not careful at all, customers will be on your neck .
