*I like how quiet it is, how well it works and **Fastly.Cool** , This was perfect to help air out a guest room and to use instead of AC when I only want one room kept cool. Works great!*
Great Vid, helped me Fix some old floor fans i was about to toss, now they are flowing like new.....I used some high quality silicon lubricating grease worked quite well....thanks a lot!
5 years and counting on helping people like me who knew NOTHING about floor fan fixing until watching this. Thanks for saving me $40 on a new one! I used WD 40 and it worked like a charm (in case anyone is wondering about grease type.)
Thanks for the tip going use it. Here is one in return the piece of plastic he's pointing to @2:00 broke on my unit in the shaft. You need that peice to get the fan to rotate properly. I found that the screw securing the fan to the stand fits the hole perfectly so screwed it in and now it works perfectly. Next problem is how to replace the screw I just found a wood dowl to stick in its place after drilling it out. This sucked wouldn't recommend did it cuz covid made imposable to go get new screw.
WD evaporates quickly so a non-detergent oil or 3-M Fan Oil is better. My electric motor/fan guy never uses grease. Also there is wicking material around the bushing shell that sometimes needs replacing and some amount of oiling to prolong the lubrication servicing.
3:34 See those little blobs in the bushing area? They need to be removed and something like oil lamp wick used to replace it by pushing it in around the bushing journal and adding a goodly amount of machine oil to soak it to improve lubrication and extend service intervals. The biggest problem is slow, stuck propeller shaft due to low lubrication and resulting dry bushing and shaft surfaces. I noticed those loose blobs many times while re-servicing all too often dry fan bearings in a hot dusty climate. That material is insufficient to work well to hold oil near the bushings, whereas the ones I replaced with oil lamp wick are still working fine. Don't forget, capacitors lose power over time and need replacing after a while. If lubrication doesn't restore fan speed replace the capacitor.
This video gave me almost all the intel I need to fix my high velocity floor (Chinese) fan. I took apart my 'pedestal' fan similar to the one in this video last year & cleaned it up & changed some grease but I missed something & it didn't oscillate correctly & made a noise on high. I opened it again today to realign it. A tiny plastic nub where the motor sits was not seated. It's not made like anything I've seen on RU-vid. (It's so well made it gives me confidence that I can't screw it up. if I pay attention) To be fair I should tell you more about it, it's very cute pink & white plastic with transparent pink blades & the front & back grills have a thick plastic coating so they won't corrode. One tiny pink lever in the trim opens the front grill to remove it for cleaning & a big fat knob turns counterclockwise to remove & wash the blade assembly (1 piece) The wires off the motor coil feed into a plastic grill assembly sitting fitted over the coil. All the connections are soldered into paddles fitted on the grill. The thermo-protection unit snaps onto the side of the grill. Did I mention this is the very first time my fan has needed attention? I bought it in Japan in early 1987. It's so well made it almost pisses me off.
I had an oscillating Westinghouse desk fan from around 1954 that was still working, that I bought at a garage sale back in the 1980s. I donated it to a museum three years ago. Along with the fan, I also donated an early ‘50’s “owl eyes” Zenith clock radio (also bought at a garage sale in 1980s), and a 1955 Sears Kenmore toaster that my dad bought new. Both of them also were working.
THANKS - YOUR video was very helpful IN REPAIRING a FLOOR FAN that is over 20-years old. the FAN belongs to my Son and - OBVIOUSLY - has MORE SENTIMENTAL VALUE than ACTUAL WORTH. For those that are CURIOUS the SHAFE of the MOTAR was VERY DIRTY. I cleaned the shaft as defined in the video and I removed the old grease - which after 20-years was still PLIABLE. I cleaned the parts and I install new GREASE. I do not remember the FAN working this WELL and being so QUIET. THANK YOU !
Me watching after I gambled it yesterday just like in this video i knew nothing about fans but I did it just like this and it's blowing air on me right now 😂😂😂
Mine was a tab different in where the parts were. The hub bearing was actually out of the rear part of the motor. I must've tried to put it together like that and it wasn't until I watched three videos showcasing the same thing like no fan blade spin So thanks to your video I was able to figure out where I was going wrong. So in the rear I just had to lift up three tangs and put the hub bearing in there snug as a bug in a rug. LOL :)
Hmmm this is 2022. My fan stopped working... I was set to buy a new one tomorrow and something told me to check RU-vid and I found this. Save me some hundreds. Thank God
Any idea what's happening with my identical fan? It spins freely by hand, but there's no power. I checked all electrical ends and 120v goes all the way to the stator. No buzzing or any noise at all.
I used oil that came with my shaver, spent at least 2 hours on the whole project and did a great job in my own opinion ... but the fan has only been running smoothly for a couple of days after that ... now I still have to "start" it manually otherwise the blades won't rotate. >:-(
The spherical bushing in my fan came out of the housing when i was pulling apart the rotor and shaft. I tries hitting it with a hammer but it doesn't want to go back. Also how to remove the little metal stick on the shaft where the fan blades sits. That thing doest let me take apart the whole fan. Maybe i get the busing into the housing if i can take out the shaft.
Hello, turning very hard ? using motor with ball bearings, then will be working easily without this problem. This fans have very frequently problem with plain bearigs.
Nice video. Do you know where I can find a replacement fan motor for an older model Lasko Box Fan with the larger "deeper 20" box" ? I'm having trouble finding one. Thank you.
Even if its cheap and ugly, it can still blow air even not much, in my country, chinese made fan uses 1.2 uf capacitor, but this one uses 2.5 uf one, even if its blow no thing, it can still do the job to move air
About a teaspoon of oil, to saturate the felt around the bushings. 20 or 30 weight non detergent oil. Blue "3 in 1" oil, made for electric motors, seems good, (or equivalent). I use 30w non detergent oil. About $3 per quart at Walmart. Use a dropper to apply. I'm not an expert. This is the best info I've found. And it works for me.
I used baby oil to lubricate the shaft and bearings in my fan motor today and it works like new again. Is it okay to use baby oil for a job like this? It's the only type of oil I had on hand.
+Benjamin “Ozias” Esposti Right. Ball bearings are too expensive, so say the owners at the Foshan Guanmei Electrical Co., Ltd factory in Guangdong, China and feel they need to produce new throw-away items cheaper than the competition, never better or longer lasting.
Question: I took mine apart and cleaned everything with WD-40 and lubricated it with oil. Before it hummed a little, while not able to turn. Now I can turn it easily with my fingers, but there seems to be no power or hum. I reassembled it carefully, so the unit should be mechanically correct. Is there any issue with getting WD-40 or oil on the coil? Should I take it apart again and wipe it down good with paper towels? Any other ideas?
Wires in the motor coil are varnished, oil shouldn't affect those, otherwise a good idea to keep stuff clean. Hum & no turning: that's how a seized bearing burns down the motor. It may be dead.
Sir mera wall fan jam ho jata hai jaise hi on karta hun...aur vibration ka sound ata hai...jab main electricity band karta hun to shaft freely ghumta hai...please suggest ki on karne pe hi kyun jam hota hai...
How long was running with grease up before the next fix? My opinion this bushing called oil shintered or oil immersed self lublicating bush, with synthetic oil.
Thanks. I did clean the shaft. . But when I put the stator and rotor . Still it makes some noise without moving. .pls any tips. I don't know if it is the rotor or the stator. Pls pls .
@@theoverengineer thanks for replying. But is making sound. Like the rotor is too small to occupy the stator. But when u press the rotor. It start to rotate little by little
Ok so like- I have a kenmore fan, and now it's making a very loud grinding type noise, like if you put a plastic toy into the spinning blades (which are also plastic) how it'll make a thumping esc noise, but it's constantly doing it, for a few days now I've been holding my hand on it with pressure and it's been quieting, also something sounds like it's shaking around in the rotate button area, I don't know what's wrong even after watching this-
It's an out-of-balance issue. Any bolts could come loose, bearings could be worn out, blades weight could be uneven ... Not a diagnostic video, or all that can go wrong with fans.
Yeah, i did this and now it doesnt work anymore. Before it was just spinning slowly, I followed your instructions and now the motor wont turn on at all.
I have same motor but shaft is moving back and forth instead spining in place.I opened it and found nothing unusual.I expected maybe some broken spacer but nope.Is there any fix to it?
Note: I know some of us may think, I'll use car transmission fluid or brake fluid as that's the only lubricate I have but 1) From the research I've made, they may be corrosive and mess up the metals in the fan 2) I already tried them but they work ONLY temporarily (after some minutes your fan will be slow again. I guess you need OIL not other fluids
Good one works for a few days and back to take it a part again till you brake the thin coil wire, and you done. so far none of the oil, grease idea worked for me. Oil dry and burns as in the frypan, make it sticky.
theoverengineer : I have a similar floor fan ... after cleaning the hub/bushing ... (I thought that might be the problem) ... when I turned on ... it buzzes and blocks the rotor very very hard ... you can't move the rotor by hand ... I pull the cap ... checked ... and it seems to be fine ... around 1.8 uF. When you turn off the fan ... you can move the rotor very easily ... what could be the problem? It does it at any speed. Thanks.
Yes ... the front bearing ... when you pull it out ... it's a pain in the neck to put it back ... but now that the part is free ... I noticed the bronze bearing on the back. It disappeared too ... and when you start the motor ... the coil pulls the rotor back ... if you push the rotor shaft forward with a flat blade screwdriver ... then it starts spinning ... like new. .. But here is the problem ... where will you get those bearing parts from? ... I'm thinking ... maybe ... I need to put a real ball bearing ... they are cheap and easy to find I know ... a lot of people are thinking ... why bother? ... just throw it away The mindset of throwing everything away ... does not allow your brain to think about problem solving ... I must say that better than that, is when you develop a mindset of being a person with a patience to study the situation that allows for planned solution including the throw it away!!!
Exactly the point of this channel. I often get `spare`parts from thrown away items. Never came across those bearings new. Sub in something that fits, shoot a video on how it worked out and post a link here.
I just got a fan that is super loud, any way to make it less loud? On level 1 it is just so loud i cant hear the TV, and on 3 even worse. Is that normal for new fans and it will go down, or can i lower the noise by screwing on something?
@@theoverengineer the fan actually works well, the issue is that on speed 1 it sounds like speed 3, and on speed 3 it sounds like speed 6 (even thought it only has 3 speeds). Is there a way to open up and lower the fan speed somehow? I have to take it in to the repair shop otherwise. Thank you for your help!
@@theoverengineer Is there any way to open it up and lower the voltage somehow? Or i have to take it in to a repair shop or similar? For the person without engineering skills i mean. ;)
Then why isn't the oil that came with my shaver doing the job? I cleaned the old stuff off first and everything. The question is not whether it worked initially, cause it sure did, but after just some days, the blades are almost too stuck for the fan to start rotating on its own... This has happened with both my floor fan and table fan.
@@theoverengineer yes my fan blade has a bit of a crack and just fell off last night. we bought a new fan, but i still want to fix the old one, i've been taping the blade up cause i coudn't find a replacement , it's a steel fan btw :) thank you so much for getting back to me.
Probably shorted everything. Check motor for continuity ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eOTTGYtwAdk.html, shown on this solenoid at 7:55 - on
The whole point of the video is to teach amateur to fix the fan but if you keep skipping the video and not showing the process it's self of how you open the motor how are we supposed to do it. It's quite ridiculous if u ask me more like a scam video
The whole point of the video is to share one way what I do with the problems I have. It is not a lesson, not trades training, not a tutorial, people go to school for that and learn from real instructors with a clue.
