Picture of FAN repair
Dissected.PNG
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.

ThermalFuse.PNG
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)

 

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!

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.

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.

Good luck

see if the gear of the fan is not align

repalce its capacitor

This instructables program help me so much. I don't have to go every now and then to repair shop.
