Cost Estimating Best Practices American Institute of Architects, Nov 2008, AIA East Bay Chapter Bathroom Fan Replacement - Average Cost Per FanTo lower Bathroom Fan Replacement costs: combine related projects, minimize options/extras and be flexible about project scheduling. I bought a new motor for my bathroom vent fan and it came with a ground wire. The old motor does not have a ground wire, or not that I can see. What should I do with the ground wire? As long as the motor is solidly mounted to a metal bracket and in turn solidly screwed to the fan housing then the ground wire may not be needed. The old fan may have gotten it's equipment ground from this method so the new one can also. It also possible that this replacement motor is also sold for appliances that have plastic housings so the ground tail is required. If there is no grounding means existing then the same really applies. There is nothing I can think of that says if you have to replace a small motor like this that you have to upgrade the circuit feeding it.

If your ceiling fan doesn’t work, you can save time and money by repairing it yourself.

- A ceiling fan can stop working properly for a variety of reasons, discussed here and on successive pages of this article. On this page, we show you how to deal with a fan that doesn’t work at all because it isn’t receiving electrical power.Consider the sound rating of your fan. - The next thing to consider is the sound rating of your new fan, which is measured in sones.New fans usually have a sound rating somewhere between 0.5 (very quiet) and 6 (very loud) sones.Some people prefer to have very quiet fans, while others value the privacy offered by louder fans, especially in public areas of the home.Like the CFM, the sone ratings of new fans will be printed on the box       Sources:How to Repair a Ceiling FanCooling and Ventilation Systems Category: Bathroom Exhaust FansFanMasterHow to Install a Bathroom FanWritten If the motor is not turning, then you probably hear a harmonic of the line frequency. 480 Hz is the 8’th harmonic of 60 Hz or the fourth harmonic of 120 Hz. My bet is on the latter.

You here that particular harmonic because it happens to be close to the natural mechanical resonant frequency. In any case, the motor is defective and should not be energized as it is a possible hazard.Written Let me try to answer this one. The fan is most likely an induction motor and either the bearing/s or the bushing/s of the rotor is stuck up due to dirt or its worn out. In any case, the rotor can't turn so the whole thing vibrates in resonance to the magnetic field being created by the AC flow in the stator wire and the rotor. Another case would be that the stator winding is shorted somewhere and because of this the magnetic flux being created is not enough to make the rotor turn and again just make the whole thing vibrate. And if you found out the frequency as 480 Hz, then that must me the resonance freq or it could be the harmonics of the whole thing. Hmmm. Written These motors often have sleeve bearings, whose lubrication deteriorates with age and stalls the motor. The motor may be “impedance protected” which limits the current in the winding to value low enough that it will not overheat the copper winding and burn the insulation.
