Hello, I just found this forum searching the web. A couple weeks ago I pulled this Sanyo Superior desk fan out of a pile of trash. It was totally caked in cat fur and dust. Underneath all that was a really nice looking device. It really fits in with my decor and works almost perfectly.  Only problem is it intermittently makes this high pitched whining sound. I am wondering if anyone has an idea of what the issue could be. Here is a recording of the sound it makes. I removed the cage and the blade to eliminate possibility of rubbing. https://v3.fastupload.co/file/4455 The sound is coming from the motor part. Sometimes it seems to have to do with the position of the fan head but it also comes and goes without being manipulated. The sound is extremely annoying and drives me up the wall when it happens. I tried to open it up to see if I could clean more thoroughly, maybe oil something. I can't get it open past this  because a) both the screws are completely stripped, and b) the plastic retaining ring with English and Korean writing is really stuck. I even tried going at it with channel lock pliers. Since I don't really have a plan as to what I'll do once I'm in there I wasn't very aggressive resolving either of these. What should I do about this? Also, because I am always curious about this kind of thing, where is the model number on this? at the back of the base there's what looks like a serial number. There's also some discoloration from probably adhesive sticker now fallen off. Thanks in advance for any assistance.

First off I have no knowledge of that style fan. I am however very familiar with stripped screws .You need a screw extractor,works on a drill.Not an easy out,the same yet different.An easy out by name are easier to break (WONDER HOW I KNOW THAT?)and then it really becomes a mess.A screw extractor like the pic also has a drill bit the proper size for the extractor.They have gotten me out of many a pickle on fans,cars,etc.I have dulled the drll bit on hard bolts, so I just matched the bit size.

TRY DRIPPING SOME OIL RIGHT WHERE THE SHAFT GOES IN THE BEARING AND SEE IF THE NOISE GOES AWAY

Thanks for the info Paul. What I am wondering before I start going to such potentially destructive lengths, is whether there is any benefit to doing so. If it was easy and safe I'd open it just to see if there was anything obvious to be done. But this seems like a real can of worms. Assuming nothing breaks in the process I'll at minimum have to find replacement screws. I have oodles of wood screws and some machine screws but I doubt an exact or even approximate match for whatever is there. So without a better idea of what is the goal I will wait. :)

Tom Do you mean from the front? Like in the 2nd picture on the tube in the middle that the blades attach to? I was concerned about putting oil in it that it'll fling oil all around. I have made stupider messes in my life. But no? Thanks!

OK WHAT YOU CALL THE TUBE IS THE SHAFT AND YES WHERE THAT GOES IN TO THE ROUND BUSHING IN THE FRONT TRY PUTTING A COUPLE F DROPS OF OIL THERE AND SPINNING IT BY HAND TO WORK IT IN . THE REAR WONT BE AS EASY AS YOU HAVE TO GET THE OSCILLATOR KNOB OFF THEN ONCE YOU GET THE REAR MOTOR COVER OFF YOU CAN GREASE THE OSCILLATOR BOX . THAT GRILLE KNOB YOU SHOW AROUND THE CENTER OF THE FRONT SHOULD BE ABLE TO COME OFF COUNTER CLOCKWISE WITH CHANNEL LOCKS AT WORST... WHERE DO YOU LIVE ? I AM SURE ONE OF LOCAL FAN CLUB MEMBERS WOULD BE HAPPY TO HELP ...THEY ALWAYS STEP UP

If it comes to it,they should be modern style screws. Once out Ace hardware should have something to work.Ask them and they will size it . Hope the oil helps. Last edited on Thu Aug 26th, 2021 01:48 am by Paul Carmody |
