Oscillating fan problem
Hello,
We have an oscillating fan that is one of the more heavy duty models; the base is a telescoping pole and all the electronics are within the upper portion that sits atop the base's pole. Exact model name: SMC "Stand Fan" made in China (of course) and it's 6 years old. It now hums but will not spin anymore. I would assume this is a typical way for these to die. Anyone hazard a guess what part is worn out and is it worth the effort to fix? Thanks! Be (in very hot Dallas, TX) |

Disassemble all of it, clean the 'goo' out and then saturate the oil pads around the self-aligning bushings with good oil, put a drop on each end of the shaft before re-assembling and you should be good to go for more years. I just did one last week and also found they didn't wire it correctly. HI and MEDIUM were swapped - not any more. Never did it before? If you have a digital camera, take lots of pictures so you can re-assemble it as it is (was). GG |

The solvents evaporate and leave the thick stuff, pretty much back where you started. If you were totally nuts, you'd use Nye Oil II - about the best synthetic light machine oil there is. The bad news is the Nye oil is about $5/oz. The latest version of 3-in-1 seems to be OK. You can get it at Home Depot. GG |

It will soften thick lubricants for a short time, but if all else fails, get a couple drops of oil from the dipstick in your car. -- Service to my country?

Be Well, all that work, then it ended up getting thrown into recycling anyway. There was no much that I could see; the interior was fairly clean; I put oil on the spindle and it seemed to turn better (not too freely though). Bottom line: when I reassembled it, there wasn't even a humming noise. This thing was dead. Nonetheless, it was some father and son time with my 10 year old son. Bought a smaller unit from Home Depot for $22. Be |
