3 speed desk fan repair

[johndee]

Hello: I bypassed the broken switch and wire-nutted the white power
wire with the red wire. There are 4 wires total in the switch: white,
red, blue, and green. My first question regards when I wire-nutted all
4 wires together. I plugged in the fan, it ran, and then it smelled
like it was burning up. Sure enough, the multiple plates of metal
surrounding the shaft of the fan were hot, well, warm. So, I took that
apart and put only the white and red wires together. No smell after 15
minutes. Question: Why did it become hot? Second question: What is a
suitable lubricant for the fan shaft magnet that spins to stop the
chattering? This fan is 7 years old and I am curious to how long I can
keep it going. Thanks in advance of replies and for recommendations on
basic electronic books. John D

do not put all wires together, if your white wire
is the power, the other wires are the 3 speeds
only put one wire at one time to the white.

does it have a motor start cap on the motor?
there known to be faulty.

as for the oil
i have the same prob with mine
i use a friction proofing oil.
