Vornado very slow
Copied this from someone else who fixed his fan. Tried it and it made a world of difference. Spins free and easy, no more noise."I have had the same model for almost ten years, and have had to lubricate it twice - both times when the fan stopped rotating. It's obvious that Vornado never intended the bearings to be serviced, but if you're patient, it can be done. You must remove the front louver section (press the three clips inward gently). Then firmly pull the fan toward the front, off the shaft. Then remove the four nuts on the front of the motor housing - you'll note that the bolts appear to be free-floating, but that allows re-assembly after the bearings are lubricated. When the nuts are removed, firmly pull the front of the motor housing toward you. This may require a firm pull or GENTLE prying, as the rear bearing sometimes doesn't want to let go. When you have the front portion of the housing and shaft out, hold the housing and pull the shaft out of the front bearing. Again, this may require a steady firm pull straight back. When the rotor & shaft are free, you'll need some very fine emery paper to remove the varnish that's built up on the shaft (it's unmistakable where to clean the shaft.) And I never attempt to do anything with the front and rear bearing themselves - too much work, and cleaning the shaft does the job for me. Then clean everything up carefully and lubricate the shaft where it enters the bearings (and maybe a drop in the rear bearing itself.) I use a very fine machine oil that I bought at Sears, but I think any good oil would work. Then, it's re-assembly time - shaft into front bearing, shaft into rear bearing as the motor housing is put back together (lining up the bolts), four nuts on the bolts & tighten (firmly, no gorilla), press fan back on shaft (don't force it too far on - it'll stop when it's in the right place), plug in and check, re-attach front louver (just press - the clips will snap easily into place.)"
