So I recently repainted and resoldered all the wiring on this GE fan. It ran before I took it apart, however even then it needed a push to get moving . When I flip the switch, I get the classic BRRRRRRRRRR noise. At first, it was able to spin up pretty good after a little nudge, and keep going. After a minute or two of trying things out it will now only spin up if its pointed at the ground, and will eventually come to a stop when upright. Its also getting pretty warm. The bottom label says to oil the bearings with automotive oil but I wouldnt have thought thatd be enough to stop it completely.

GE fans are known to have weak bearings. Does the rotor shaft have much play in the bearings? Will it run perfectly if held upside down. Both of those could indicate worn bearings. That said, I'd give it a good drink of oil first and see if that helps. 3 in 1 in the BLUE can or Zoom spout are the usual recommended brands. Never use detergent oil in a fan.
