How to fix an electric fan

I can feel that my electric fan has been struggling these past few weeks but kept on ignoring it.Then, just a couple of days ago, I woke up and found out that it already had enough. It won't turn and was just stressing its "engine" :) Fortunately, I have been tinkering and fixing electric fans at home since I was 13 so dealing with this one wouldn't be a problem.



Please watch the video to see exactly what's happening. (Apologies for the poor video quality and my horrible voice :))


As I've mentioned - as long as the motor still humms or you can still feel that it's still trying to turn the blade, then there's still hope! The problem with the fan lies on  two parts - the shaft (where the blade is attached) and the bushings. Dirt and dust accumulate on these moving parts over time leading to rust which gives your motor an extra load. Sometimes strands of hair also accumulate in the bushing and shaft (as in the case of my sisters' fan) and they have same effect as rust. If your fan's motor is stressed out long enough - it burns out and worst case is that you also burn your house :(

TIP: If the motor has already given up on you (no more humming or no more movement - NR na siya) then its already up to the professionals to fix this. Sure you can buy a new motor for around 200 to 300 pesos but wiring it and having to worry about the motor's alignment is just too much for first timers ( believe me - I've been there). As my mom usually says - its not worth the hassle.

To get access to the motor - we have to remove the blade and all the covers. (MAKE SURE THE FAN IS NOT PLUGGED IN)


Removed the blade cover - see how much dirt is in my blade - so that's why I've been having asthma attacks often.

Remove the screws here..

And here to remove the motor's cover..

This is why my motor's having such a hard time - there's dust everywhere! TIP: Don't be like me - clean your fan at least once a month by washing the blade and everything that you can remove with soap and water. Every two month, it is advisable to remove the motor's cover - and brush out the dust there. Remember - an ounce of prevention is worth more than a pound of cure!
Remove the screw which holds the oscillator (normally at the bottom) - some models have clips instead of screws.

 Remove the clip near the end of the shaft - this serves as a guide/stopper for your fan's blade.


Remove the  screws that secure your motor.


Pull it out carefully - be mindful of the wires connected to the motor as pulling out one of these wire will damage it.


The fan has one bushing in the front

and one at the back... both of these would have to be replaced.

In this model -you just pry it out with a flat head screw driver or a long nose pliers. Some models have clips that you need to pull out.

Here's what inside - the bushing, the foam pad and the lock/cover (you will buy a new set for around 25 pesos)


This is the fan's motor shaft - you need to have just the shaft replaced - the shop where you'll buy your parts will put in the new one - make sure you bring this with you. Save the spacers since you will need it when you put it back in. you could also replace this with new ones - just make sure you have the same height.

The new set and the old one.

Putting back the bushings may be a bit tricky and need's patience. I broke the cover the first time I did this - its a good thing they are cheap. Place the foam and the bushing where it belongs and place the cover on top. Push in the cover carefully using your screwdriver - you will end up with one side in and the other side still out - lightly tap it in using a small hammer (its a tight fit) and once it locks - your done!  (the same for the bushing at the back)

 See that the old shaft is already damaged and rusted.


Put it back together - make sure you check if the shaft is rotating freely before you put back the cover. What I do is to attach the blade and see if the fan works at all. If the blade is not turning freely - your alignment is off - you need to move the bushing a bit to align the shaft properly.

After everything checks out - put the fan back together.

Everythings now clean and it looks great!


YES! YOU CAN FIX YOUR FAN! :)

  2. hi xtian! Thanks for appreciating this post. You could usually buy replacement bushings at stores which sell electric fan blades and parts. If you are located near San Pedro Laguna, you could try out Ohms in front of Watsons. You could post where you live and some of the other readers might know a shop near you.

    1. Hi Arlevin, I'm not quite sure what happened to your fan and how it died.. but there might be a possibility that something might have tripped in the buttons or worse, the motor might have died on you completely... I will write about how motors are replaced soon :) We have several fans that need new motors and I'm thinking of doing it myself (I hope I get the time to do it hehe)

    1. Also i voltmetered the speed switch, when i switch to 1 speed position, all (1,2 and 3) position has 230v reading, is this normal or the capacitor is busted? same when i switch to speed 2 and 3.

  6. Hi tipidshop - I think you've burned out your motor - does it still hum when you turn it on? What you can do to test if your motor is still okay is to set your tester to continuity and check if the wires for 1,2,and 3 are still to the power lines (kind of hard to explain without pictures - I'll write an entry for it soon) - you could also bring it to a shop which sells fan motors and have them test it before you buy a new one. If you had a hard time turning the fan's blade - there's a good chance your bushings and shafting will also have to be replaced. It is normal for the switch to carry 230v reading - that the current running through it. Be careful when working on your fan while it is plugged in okay - you might electrocute yourself. Don't worry - fixing your fan won't cost you that much - the last time I checked a new motor costs around 150-250 pesos while bushings, shafting and other small parts will cost you another 50 pesos. The capacitor (though it is rarely the culprit) costs around 30 pesos. Thank you and hope I have somehow helped you.

  7. Hi, i am trying to fix our electric fan in house. It stop working due to overheating, what must be the cause of the overheating?
    Thanks

    1. Hi Haneef - oftentimes - overheating is caused by worn out shafts and bushing - the shaft gets stuck and the motor can't turn it. You can check this by trying to turn the blade - if it doesn't turn or rotate freely, you need to replace your shafts and bushings. Motors usually have a small thermal fuse - try replacing that too instead of replacing the whole motor.

  8. hi, i'm trying to fix my fan and had it cleaned blowing all the dust inside the motor enclosure, the problem is it needs to manually rotate the blade to work, speed adjustment is ok. what seems to be the problem?

    thanks,

  10. Hi Archie! Thank you for the very informative article. I wonder if you have any tips on how to troubleshoot the swivel of the fan. Thanks in advance.

    1. Hi Alex! Thank you for leaving a comment. When you say the swivel - is it the mechanism that allows it to oscillate (pane left and right) ?

  11. Hey Archie, thanks a lot for your instruction on how to fix an electric fan, I enjoyed it a lot.

    What is this you say "NR na siya" and about pesos, you are one Pinoy, here in the Philippines or where?

    This thing of being wanting to help others, that is indeed a proof that man is good, but atheists you know them, I seem to find them to be a very nasty lot when it comes to God and the things God made for us humans.

    Well, that is another story; I wished I could just avoid altogether discussing issues with them in web forums because they don't reason, they just keep dodging the issue and instead throw up foul language against God and Christians and anyone trying to reason with them about how they think -- they don't, they just emote and regurgitate stale slogans they read from their deceitful masters, like "If everything has a cause, what caused God (the real statement is "Everything with a beginning has a cause...)."

    Hope you are not a nasty atheist, some Filipinos here take to them US atheists also, imitating US atheists and behave like they are so smart, but it is all insults with them and dodging the issue and regurgitating (i.e. throwing up) rancid sour bad-smelling slogans from their deceitful masters.

    Okay, coming again to this contribution from you on how to fix an electric fan, it is really well-done, and as I said, that you took the time and trouble to put it in the web for everyone to read and benefit from it, that is the proof that man is good, and one of man's goodness is the desire to share useful knowledge, and information of facts and truths with other humans.

    Yesterday I went in the late afternoon to SM North Edsa to buy another floor fan because the one I am using is seemingly "NR na siya" (what is NR? Is it Near RIP?), and found out that the prices of electric fans are today some 6 times more costly than when I bought the one which is now what you call "NR na siya," so I said to myself better come back on July 19, 20, 21, 2013, Friday, Saturday, Sunday, big sale days with discount as much as 70%.

    Then suddenly I recall that I used to fix electric fans also, and the trouble could be the capacitor, because the rotating assembly is moving freely.

    To make a long story short, I decided to dismantle it this morning today, but first look up the web for people like you, who love to share useful information freely with other people.

    By the way, are you here in the Philippines or where are you living?

    And please, don't act stupid like atheists do, replying like "I live in a house," they usually resort to making out that they are so stupid in order to not know at all how mankind has reasoned to the existence of God from the facts of the universe existing and you and I exist and operate and yes produce babies whom we love to bring up to be also useful members of mankind.




    Thanks a lot.

  12. This is really a great attempt to make small repairs at our own end. But as suggested in your post, when the things are not supposed to be fixed by you, its highly recommended to hire any professionals rather than putting yourself in danger of electrical short circuits or blasts. Sometimes a little unprofessional touch may cause to tampering in the whole wiring system of the building.

    In India, for the same services there is Marammatwala.com where people can hire technicians as per their requirement,

  13. Wow great information. I wish I had looked for it a few days ago. I have a fan that sounds very similar to the one in your video. It would hum when I turned it on but i'd have to spin it to get it going. Last night I turned it on and it came right on and I was happy and surprised, but this morning I went to turn it back on and nothing. No hum at all. I had originally got this fan to use as a Halloween prop at a thrift store because it oscillates but now its not doing that any more either. Since it doesn't seem to have any juice left in it should I give up on it or do you think there is anything that can be done? Also even if I can't get the blades turning again is there a way I can at least get it to turn back and forth or is it all tied in together? Thank you so much for all the info.

  14. Thanks for sharing.

    I need to fix my stand fan. It doesn't swivel evenly and sometimes it gets stuck on one side as it tries to still turn but it can't anymore (there's a knocking sound). I feel there is problem in the oscillator. Any ideas?

    Thanks.
