My faithful oscillating fan has given up the ghost. I know I can
go buy a new one but I like tinkering and fixing things so I'm looking
for some help.
1) Its a three speed table fan with thermal protection that is about
20 years old.
2) There is no hum indicating its trying to spin and giving it a hand
3) I removed the capacitor and tested with a multi-meter on the ohm
range. The "resistance" increases steadily to a large number and then
goes to zero ( its a 4 uf 230V cap ). I think this means its OK??
4) There is a "device" in the circuit coming from the neutral to the
cap (ie . white---> "device" ---> cap ). Its tied with string on top
of the winding and inside a clear plastic sleeve, is cylindrical in
shape with one end pointed and coloured orange. There are some
markings on it but I can't read them without removing it first). The
AC voltage before the "device" is 115V. Voltage after the " device"
Is this the thermal-protection? If so does this indicate it's fired
and should be replaced? ( I haven't tried to bypass it because it
means snipping some more wires)
5) Near as I can tell there arre no "brush's " but I haven't fully
dissasembled ( because I don't figured how to get some of the parts
Most important: I'm reasonably handy but my electronics/motor
knowledge is basic high-school level( ie I know what a stator,
rotor,armature,commucator etc. are but not sure I can relaibly tell
you if its a split-phase, or induction etc type motor :) )
Any suggestions are appreciated
