I had accumulated three floor standing fans which had stopped rotating. Had cleaned and oiled its shaft bearings and even changed the squarish capacitor but still not turning. Was about to throw them away when I thought "... what's the harm in dissecting them, I could learn something from it...!!"

I had asked a few servicemen and all I got was a short "...there's an internal thermal fuse...". I trawled the web for months but just could not find any info on where the fuse was and how to replace it. Finally I decided to sacrifice one of the fans and dissected all the wires going into the windings. 

From this came the schematics of the fan, but only up to the motor windings.

This instructable comes in 2 parts: (I)Troubleshooting and (II)Fuse replacement.

Step 1: Materials Required

Cross head screw driver
Flat tip screw driver
Scissors or Pen knife
Soldering Iron and some Solder
Some string about 0.5mm in diameter 
Spare wire, about 60cm long
Capacitor 1.4uF 450VAC (if required)
Thermal Fuse 130degree C, 1A, 250Vac
  (note: I could only find a 2A 130deg replacement @$1.50SGD a piece from the local electronic component shops. Sorry I don't have equivalent part number from Mouser, RS n Digikey)

<p>Can you help me??</p><p>how the table fan oscilate </p>
<p>Hi, i need help i have a problem fixing my fan, i cleaned &amp; oil it, but my fan doesn't work still vibrating, i tried trouble shoot it looks fine all in tack (i think). i check the capacitor still working. what seems the problem of my fan?</p><p> 1) I have a question how can you know if the therma fuses is not working. (if still vibrating does it means that the therma fuse still ok?) </p><p>2) Is your fun same problem mine. (only vibrates)</p>
<p>Hello</p><p>A simple question. On the schematic diagram shown on page 2 &quot;Troubleshooting&quot; point B of the capacitor is linked to neutral (blue wire) via the thermal fuse </p><p>BUT where does the C connection of the capacitor (white wire on the diagram) is linked to?</p><p>Thanks</p>
<p>I followed all the steps and was able to fix my fan though it's a little complicated but was very adventurous and this is actually my first time....and I kind of did something though not healthy but it worked as related to my &quot;terminal fuse&quot; I was able to get a new capacitor but couldn't get the terminal fuse so I short-circuit the fuse don't know if that's the right word &quot;short-circuit&quot; but it has a good ring to it. anyway this is what I did, I rowed the fuse with a very slim wire and solder but end and boom I have me a working terminal fuse....and I CAREFULLY followed the rest steps. I don't know how long it will live but it's working awesomely well. ONLY TRY THIS IF YOU CAN'T GET A NEW TERMINAL FUSE.</p>
What type of fan did you work on?
<p>where does one purchase a capacitor for stand up fans.</p>
<p>how do i disconnect the timer and still have my fan working</p>
<p>I have a panasonic table fan.i want to change the bearing of the motor but when i remove the motor i didnt realize there is a connector attached at the coil winding.the connector pulled off from the coil winding.Is there any way to solder them back or dispose the fan? </p>
I have problem, i had a bajaj table fan., fan wings are made of fibre those were broken last time because it fell down from a table, afer that i cuecked with the electrician he told also want to change the capacitor since it's not pushing to rotate, but my issue is wings are breaking all of a sudden during rotation., wat is the reason for this...?
<p>I have a weird problem with my fan. Its panasonic's . There are no problems with the 3A fuse, the capacitor nor the grease. So i thought that maybe the circuit is out so I decided to run this stupid test. I turned the fan on, and touched the fan directly( to check whether there is any flow of current) since i dont have a test pen thaha. So i got shocked by the current! The current is present! SO WHATS THE PROBLEM HERE??? PLEASE HELP!</p>
Any idea on standing fans, that is able to spin briefly for approximately 2 secs and just stops. I have accumulated 3 fans of different makes and brand. They have the same trouble too! Tried replacing the capacitor which doesn't see any improvement. Also tried to short the thermal fuse contact that don't help.
<p>The grease applied to the spindle gets hard by heat and time. Soften it by spraying anti rust oil, scape it, and replace it with soft heat resisting grease.</p><p>Good luck</p>
<p>see if the gear of the fan is not align</p>
<p>i have a problem with the speed of my fan, how can i increase its speed...?</p><p>tri-staterepairs</p>
<p>repalce its capacitor</p>
This instructables program help me so much. I don't have to go every now and then to repair shop.
