Changed the cord on a Westinghouse fan and the motor just hums.  No obstructions.  What does this mean?  Thanks.

When you say you changed to cord, do you mean the head wire from the motor to the switch? If so, it is probably wired wrong.

What model of Westinghouse is it? There were lots of Westinghouse fans that had what was called a split phase capacitor motor (PSC also known as) and those fans won't run if the capacitor (which is the little sardine can looking assembly in the base of the fan) is bad, usually those capacitors have the value rubber stamped onto the top of the capacitor, I believe my fan that has such a motor in it has a 4.7 MFD 330 VAC Capacitor in it ususally they are non-polar capacitors and actually if you find a regular ceiling fan run capacitor of a similar MFD Value but higher voltage like 440 VAC then the fan should run again.
Hope this helps.

OK, yes you already posted about this fan in another thread on here and having similar issues, just as I said in the other thread concerning your fan, it has a shaded pole motor which usually if they aren't working, it means they're toast and need to be replaced or rewound, which with a cheapie fan like this (the Lively Aire Fans by Westinghouse were basically their dime store models) aren't worth rewinding the motors on as it would cost more than the fan's worth to rewind the motor so you'd be better off finding a good motor from a parts fan and repairing it that way.

When you turn it on & the motor just hums, can you turn the blade freely? If not, the rotor is being pulled against the stator. If that is the case, you either have bad bearings or the motor is not aligned correctly. Did you change the cord just going to the base, or the cord to the motor?

Yes, this is really likely!  Levi mentioned that he's pretty sure the motor is shaded-pole type. There is not much that goes wrong with those, other than shorted-out or open circuits.  If the motor still hums but not smokes or pops - probably the winding is OK; and you have a mechanical problem.


As Stan said above; the blade can turn perfectly freely with power off, then it magnetically locks up when the motor is turned on.  There is a lot of magnetism between the rotor and the motor stator (housing). If anything inside is loose, improperly shimmed, off position, or not fully tightened / overtightened - there will be problems. The rotor will magnetically cling to the side and bind up when power is turned on. This can also happen if the inside of the stator, or the outside of the rotor is coated in gum, grease, dirt or paint. These will fill up the air gap and cause drag.

Hope this helps!

did the fan run before you changed the cord? those have a unique mounting system & uneven pressure can bind up the rotor in those.  look for the mounting screws-- they split it into halves--- Lawrence
