    Re: How to oil electric fans

    Due to popular demand, one of our resident DIYers, Hot Daddiy, just wrote an article on Repairing Electric Fans.

    Thanks Hot Daddiy!

      Re: How to oil electric fans

      I finally had time to disassemble my electric fan (the blades are turning slowly like something's stuck up) following Hot Daddiy's article. Based on the symptoms, it appears like a dirty or bad bushing. When I got to the bushing itself, it is clean but is stuck very tightly to the shaft. Is this normal? No matter how hard I twist it, I can't get it loose. In this case, do I just need to oil the bushing directly or the felt washer? TIA.

        put some oil and let it settle muna, pag nag-loose na yung bushing sa shafting you can clean the felt cloth that absorbs the oil, check the bushing and shafting for scratches or any damages, you can clean the shafting by placing it to an ordinary drill, use no.240 or finer na sandpaper while spinning it sa drill, don't forget to put oil on sandpaper, and be carefull..

          electric fans and oil?
          i don't think it goes together (not 100% sure)

          normally you put grease in electric fans

          for the bushings (just replace it with new, it'll not cost much)

            Except for the box type square fans, which usually on some models-are a pain to oil the front bushing because of the oscillator motor blocking the path.

            I need to bend a length of G.I. wire in such a curve as to allow flow of droplets along the wire down into the shaft and bushing. Hard to see how much actually got into the bushing.

            BTW. also heard about greasing fan bushings, so which is the right way? Oil or grease? anyone?

                We usually use a - light machine oil. This is easily found in hardware stores, including those in malls, some popular brands are - Singer Oil (because its frequently used in sewing machines) 4 in 1, and 3 in 1, from different supplier/Manufacturers.

We just take it to the small electronic repair shops around town and they would usually charge Php150, good as new na pagbalik ng electric fan

                      hi! new here...
                      thick oil like motor oil is good... but you have to check first if the bushing or bearing is worn-out (or have play), then you have to replace it.
                      if the bushing/bearing is fine, you have to disassemble the fan motor (stator assy, rotor assy, & housing) just to properly oil the bushing and the shaft.
                      the rotor shaft may be corroded, so ready a fine-grit sandpaper to smoothen the shaft so as not to nick the inside periphery of the bushing (soft material).
                      then proceed in oiling the oil felt & bushing... wipe excess oil. you don't want oil to contaminate the windings.
                      then put it all back together again.
                      check for rotor shaft play... max is horizontal play of 2mm.
                      be very patient in aligning the motor shaft/rotor with that of the housing & the stator.

                      that's it!

                          This is very interesting. I have brought our fans many times before to a repair shop and its always the bushing that they replace daw..

                                Usually thermal fuse are inside a black tubing running along the wires in the vicinity of the motor winding and the capacitor. You can only distinguish it if you pinch the tubes and feel a little bulky inside compared to a joined wire connections. To check a thermal fuse you have to use a multimeter and check its continuity by setting the multimeter in X1 at around 5 o'clock position. The dial will move if its ok and defective if no movement if you connect it end to end.
