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..
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
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.
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.
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.
YES! YOU CAN FIX YOUR FAN! :)
