Fixing an oscillating fan.. kind of.

- Trying to repair the oscillating feature on a Dowell floor fan. Learn a little about what makes your fan automatically turn left to right.
Although the repair was a failure, I've located the broken part and you might find it interesting to see how the fan works and what part broke.
This is a Dowell Philippines floor fan with 3 speed settings. The main function of the fan works as expected but the oscillating feature no longer works.
After taking the fan apart and getting access to the rear gearbox, I was able to find a nylon gear / shaft is broken. I tried to repair the part with super glue and a 2-part epoxy but neither were able to create a strong bond.
Ultimately, I need to find a replacement part instead of trying to fix the existing one. I've already reached out to Dowell to see if they can supply the part.
I also discovered another problem which is the rotary 3-speed control switch. Inside, the PCB has broken which causes reliability issues. A replacement rotary switch is a common part and sells for around P120 ($2.50)

YOUR VIDEO WAS GREATE.. ITS HONEST ACCURATE AND SHOWED EXACLTY HOW EVEN A GOOD TECHIE CAN BE OUT SMARTED BY A SEAMINGLY SIMPLE REPAIR 10/10
Excellent video explaining how the fan turns. Very well explained. Thank you very much for sharing you knowledge. Really enjoyed it.
Nice video.. After putting super glue, add a metal pin or small nail on the center or hollow part and fill it up with hot glue or epoxy to make it stronger.. I've made cheap repairs like this with broken fan parts bracing it with metal and hot glue ( quick repair) and it still works! :-)
Nice idea. I hadn't thought of filling the hollow section but of course there's no reason for it to be hollow so filling it should add some good strength. Thanks :)
Nice fan. metal blades! Very informative and succinct!
Thanks for the detailed explanation!
I've had good luck plastic welding some plastics that just will not glue up. Option 2, try the ABS "glue" for bonding water pipes together. That stuff more or less melts the plastic. In a way it's like the plastic welding with no heat involved.
Hmm maybe I'll try that ABS glue first since it's likely to be less destructive than a soldering iron or other plastic welding choice. Thanks for the tip!
Also, if you can, try drilling shallow, minute holes (1.5 - 2mm) on both pieces to be joined so that the adhesive will have recesses to seep into.
Good thinking. I'm glad I made this video, so many good suggestions from people :)
You might be able to use a soldering iron to melt the broken part back together.
Not a bad idea, worth a shot. Thanks :)
Learned about the wormgear part. What about drilling a small hole through the centre and use a toothpick (dowl) that way you are not relying on just the two surfaces to stick to each other.
you can also go to raon in quiapo, you can find lots of electric fan parts and other electronic stuffs there. keep it up bro, im a fan!
I wanted to learn how fan swing works. I understood that.. so thanks
We have that same problem but we fix it, and nice video! helps me a lot! thanks!
a 3d printer might help with those plastic parts.
It gave me an idea about my electric fan that has the same problem.
If I ever travel to the Phil., Your likely the kind of guy id want to be in contact with :)
Otherwise, I could see myself riding it out TopGear style :P
we had some awesome 2 part epoxy we used at the body shop I worked in but I'm not sure if you can find anything like it here
I tried a 2 part epoxy without any luck but I'm sure there's several types out there and maybe one would work better than the other for this type of material.
This is me fixing fans constantly because I'm tired of trying to come up with money to buy a quality fan but I don't like the fan spinning and I might look at somehow keeping the fan from moving, that's my problem. The bearings need oil the bushings on the fans that freeze up need replacing, I haven't done this yet and I'm not sure I have enough knowledge on how to remove and replace bushings also the capacitors failing #1 problem and the replacements are made in China, they last about a year if that.
Should I remove all the grease inside where that spindle is ??
Try to make this part with 3D printer if it is not available. Make it with POM (Polyoxymethylene), that is the strong plastic. One question; I have disassemble the same gearbox and when I pull the white plastic axle one ball ejected and jumped into the garden in grass, but some other part also jumped into the garden. The other ball and one spring is still in the shaft and I have it, but one ball jumped out and one part unidentified also. Do you have picture of inside the gearbox what else could be accept one spring and two balls?. My fan is Airmax 2000 and has the same motor and gearbox bought somewhere 20 years ago.
what you could have done, was to use a soldering iron and melt the two plastics together on all 4 sides, and that should hold really well ...............
Thank you for sharing your know how.
Something like that happened to me lately. I used a zip tie to tie up the plastic cylinder and the metal.
+Chungchi Chiu interesting. Maybe I could try that :)
the screw its tightened or loosend oposite to normal to prevent it loosing
On the arm? Thanks for the info, I'll remember that for next time :)
Hi, I have an Arlec 75 cm Industrial fan that will not escalate. Can you please tell me how to fix it is it the capacitor?
Are you using 3sec elephant super glue?where is the hi lo speed button?
I know im watching this 4 years later but did you get it fixed, because mine is broken at the same place, do you know what the part is called? So i can buy it online. Im in Malaysia btw so at least i can get the name and buy it on line we are under EMCO so we can’t go out to the DIY shop to buy. Please help.
I have exactly the same problem. You would think that they would make parts that are more durable!!
manufacturers deliberately make DIY impossible so you have to buy twice. Don't give up you'll find the solution.
It's not really about manufacturers making DIY repairs "impossible" so that you're forced to buy again. On the contrary, it's mostly centred around the design stage so that the prohibitive costs of tooling to produce these intricate parts are reduced as much as possible. That's why plastics are used wherever possible, even though zinc alloy parts, or similar, would do a better job. The lower the cost, the more saleable the product, therefore the bigger the profit. That's business.
So I have one advise to your problem with your floor fan, change your fan motor to motor with two ball bearing motor and choose motor with electric oscilating , no have much problem your fan ;)
Fan: Hanabishi HVFF 16 (With Dowell Badge)
Wow very nice sir
Did you think to glue a metal rod inside the plastic to act as a splint
Havent seen a 3d printer vid in a while, is it still working?
Yeah I tried something like that with a slim bolt but didn't really help. 3D printer is still good, just feeling lazy to model the part because that would take some time to get right.
Wall fan isolates but tilts on one side and if adjusted with hand again it rotates again one time then again tilts other side pls guide the solution.
one reason to support 3d printing, its a waste somthing goes to junk because of a tiny bit of plastic, only plus is you can use the fan, just wont rotate. my 40 year old fan died this week, the back bearing had given out, nothing i could do
I have a fan that has this problem, I am not mechanically inclined at all, I am looking for someone who would be able to fix the fan...
The teeth on the oscillation mechanism are not gripping anymore any ideas what to do?
You can buy a replacement on eBay or similar sites. There's generic versions for most fans.
My one was stuck then i tried to unlock it by moving it manualy now its 360degress .... what did i destroyed
you can make a 3d print version of the whole thing :D
It's certainly a possibility. One downside with a 3d printed version is that I have to model the part first. Although it's not that complex a part. The other downside is that it wont be easy for someone else to replicate the repair in the future unless they also have access to a 3D printer. But regardless, it might be the perfect time for a new video using the 3d printer :)
just buy the replacement. its very cheap only 5pesos.
and its widely available in philippines.
Really? Where from? Junk shops?
there is a electricfan repair shop if you're near in pasig (simbahan) that sells all kinds of e. fan parts, had the same parts broken before that they have replacement parts available.
Ah, yes, fan parts/repair shops. Just brought one of our fans to a shop in Mandaluyong and they still have parts for it despite being 20+years old.
if its nikon or standards brands, you can get one easily on their service centers. else, there should be a electrifan repair shops in you area.
my standard fan (i mean standard which is the brand), still works fine until now for about 8-9years now, every 2 years or less, it needs replacement like the capacitor or need to replace the copper on the motor. which all of this cost less than 200 pesos, a huge savings if you compare it to a brand new unit.
I never had a issue against the turning functionality of my fan, it works just fine until now.
Not a waste of time Mate, not at all.
The only part you'll find is out of a new one if still on shelves...if you know what I mean. Companies make stuff to fail. They deserve a RTV return to vendor.
Yeah it's annoying. If you look at this fan, most of it is metal and fairly heavy duty. Then when you get to the gearbox it suddenly changes to plastic or nylon which is likely to break eventually. I have emailed Dowell PH to see if they can provide the replacement part. I also have the option of 3D printing the part but I'd have to model it first and since I'm not great at that, it would likely take a few revisions. If I had a lathe and all the tools, I could probably replicate it in metal :P
Just buy a new oscillator. It won't cost a lot.
Nice vidz 👍
Thanks :) Hopefully I'll have luck finding that spare part.
Good video brightness is good but Hindi mein Hindi mein
The gear box on mine is different.
+Seth Horst is yours also broken ?
The fan itself work but the oscillating function is broken.
Gadget Addict who will
Who will what?
Then who was phone?
wow
Weld it!
pro tip: super glue does not stick to most plastics..
It seems like super glue doesn't stick to much other than my fingers!
