Fan repair fail

- 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.
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.
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.
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
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.
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…
Pareces un cirujano 🧑🏻⚕️, felicitaciones 👌🏻 y saludos desde Cali, Colombia 🇨🇴
When he said "I dont have to worry about getting it right" i said he is going to Fu#% up that fan.
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.

Let's keep trying until there is nothing worth to fix (?
Like any other handyman, we all experience failure. We learn because of it. Thank you for posting this video.
You were not careful at all, customers will be on your neck .
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,,,,
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
I used to be a fan, but now I'm an air conditioner
Chinese crap motor
If the engine got burned no way fixing❤
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
You broke it, now fix it. Jump out thermal overload and reconnect the wires you yanked apart. Fix it....
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.
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 ;-)
Love watching you take apart things while you explain it like this 👌🏻
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!
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.
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.
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.
Ternyata di luar negeri juga ada tukang servis kipas.👍
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.
"Not worth fixing anymore". Because soldering irons haven't been discovered yet?
OK, soldering irons and profanity...
Once you get into windings, then it's iffy.
The most common cause of thermal fuse failures being lubrication failure, due to dust sucking up the lubrication in the bearings.
A lesson, folks! Keep plenty of lube on hand.
I'll just get my hat...
The capacitor, that black thing is probably bad.
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.
A good technician is the one that breaks it and remakes it
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?
I have never seen a Hewlett-Packard multimeter. Pretty cool.
Still made in China...
I always wanted to know where the thermal fuses are on those units. learnt something today.
Tomorrow you can investigate the word "learned"
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 you know to throw in the wastebasket!!!😁
Always love watching your videos!!!
Thanks
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.
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.
Thank you for great video just found the problem with mine the thermal fuse is blown and is only 5 dollars online
That fan is still fixable here in Nigeria, u can't just dispose that new coil because of little mistake
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.
U can bypass that fuse with a fluctuating dingleberry
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!
not going to lie, even if you managed to get it working. It prob won't do a lot
those blades look horrible
I'm a fan!
right tool for the right use. you destroyed a perfectly good lemon! shame shame.
Not worth fixing but how about the induction motor without speed control, is that worth saving?
It was an easy fix and you ruin it.you should be more gentle with the parts!!!
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.
IT´S NOT CHOOCHIN'
CCR
when it overheated it probably let the magic smoke out
Heavy handed approach and purpose of this video
You didn’t repair nothing. What the hell is this.
Couldnt it be the start run capacitor in the small black box....ooops never mind you just tore it in two. In the future before destroying the fan you might check your caps
Can you explain me what is the application of capacitor here?
@@sidd9248 depending on the motors design a capacitor may be required to "jump start" the initial spinning of the motor. Others are designed to "jumpstart" the initial spinning and to keep that motor running at the designed rpm under a load. Other motors dont require a start cap just a run cap to keep the motor running at its designed rpm under a load. I hope that helped a little bit. I find caps amazing. The fact that once a cap is energized that part can keep a virtually unlimited amount of energy depending on the cap for an indefinite amount of time. I used to install repair and even build refridgeration equipment. It took me 1000s of volts to make damn sure i insulated the caps id remove from motors and compressors before tossing them into a box or tool bag. They can be funny as hell or can ruin your day. Sometimes if your lucky itll ruin your helpers day but make your decade given the right situation. If you want to learn the hard way but laugh your arse off in doing so start with a disposable camera. Carefully disect the camera you want to isolate the flash components from the rest of the camera. Ill use national geographic as my inspiration for this negative reinforcement testing. I was a mechanic for years. I had a couple kids at a lube center my cousin ran in ft worth tx. The kids would get in my tool box from time to time wo my consent. Thats a no no. Ask any motor head. Id look for a tool that should be here and find it there,not at all,or greased up. After repeated conversations with these guys it still kept happening. Then i stepped it up a notch with verbal warnings then to a light punch in the shoulder. Im a little guy at 295 now but only 220 then so no permanent damage was done. Finally when that wasnt working i went Nat Geo on the little monkeys. I remember seeing an african in the jungle take some shiney marbles or something and making sure the monkeys saw the shine and the objects as he placed them in a mound of dirt with a hole just big enough for the monkey to get his hand in the hole. Once grabbing the items his fist clenched would keep the monkey from removing his hand and would be trapped for the man to catch the monkey. Using that idea i let Rusty see the shiney reflection from the chrome flash on the camera and i placed it in the top of my roll away box. Cap fully charged and bare terminals. I then left the area. When i returned i found Rusty sitting in a puddle of engine oil with a weird look on his face. I offered to help him up and asked what was wrong. He swore nothing. He was resting. I then started the investigation asking if hed been in my tool box. I said id know in just a sec when i reach up there and grab something i left. He then confessed he had been in the box and was sorry. Lesson learned. Good times. It was only around 370 volts.
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.
Can the metal plates from the motor be used for anything?
you should try to wind your own motor sometime.
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
I love your videos.
I was shouting at my screen ! " the thermo fuse is right there ear your fingeer !"
very unfortunate friend 😅
Why you pull out the thin wires?
Had to resub your channel. Guess UA-cam decided you didn't need me anymore, I guessed different.
What? You mean rewinding a fan motor isn't your favorite past time??
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.

Nice salvage though
Hey can you give me 20 kg tamba
Nice 👍🏻👍🏻 🇮🇳 Kuki 23|04|2022
great video
Very good skill
Its not built for repair
I don't know enough about it to grab hot wires and hope I don't get shocked.. Cool video!
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 ..
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?
gets the wire strippers after he breaks it. lol
Great job sir💎💎💎💎💎
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.
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.
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
Now this is how I like seeing a video to repair something. Fast speed while taking it apart.
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.
hahaha i love how you broke everything and I still learning a bit
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.
Testing and touching live components? surely not. Please make it clear that power is on or off for the monkey see monkey do viewers.
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.
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.
Thanks for the video bro it really helped alot. I managed to fix two fans today
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.
Very interesting
Love it!
"Not worth repairing"
Now you're talking!
thermal fuse in a fan? ?_?
Yes, most motors have thermal fuses.
you need pliers to cut the fuse. you need to remove the fuse careful Do not use force. it Will broke the winding
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
more disaster
the only thing that makes sense here is the multimeter. idk if youre that nervous or youre new at electronics- small wires solders stuff
Thank you very nice video
Appreciated
Interesting video, I actually leaned something. Appreciate the high speed too.
Oops, I've just yanked these wires out :)))
At least we try huh!? :)
Is it really worth all of the time and effort to retrieve something like that fan which someone obviously threw away for a good reason ?
By the look of it , it appears to be some, made in china piece of garbage, therefore it's not worth the time or effort to try and
repair it.
Here in Australia I could go to my local supermarket (a 5 minute walk from my house) and pay $16 and by a brand new fan virtually identical (also made in china) to the fan in your video.
If that fan was made in Japan for example *then* I would understand the reason for this video.
Sorry if this comment sounds arrogant I just don't understand the reason for it (the video).
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
