It doesn't matter what color the wires are, but black, white and green are typical. If you cut the end off one of those power cords used on computers occasionally you'll find the European brown, blue and green.

You can't reuse crimp connectors but you can replace them with small wire nuts if you prefer.

yea USA colors are white for the return, black for the hot wire, and green for earth ground.

Hobbyist and a retired engineer and possibly a test equipment addict, though, searching for the equipment to test for that.

If you have a thrift store or computer recycler nearby you might pop in and see if they have any computer power cords, those tend to be cheap and plentiful since so much stuff uses them and you can cut the end off and get a universal replacement cord.

Hi again,
Got the replacement power cord and started to disconnect then noticed the black wire coming from power cord goes to the switch  (see photo).  Not sure how to disconnect and reconnect?? Help again appreciated :-)

hmm.. good question...

you could try and disassemble the switch and try to reconnect it the way the original or cut the wire and connect the new one in like the white wire is connected.
personally, i've not seen a switch exactly like that, so I have no idea what you're going to get into if you try opening it, or even if its some sealed unit.
So, if it were me, id just cut the wire with enough room to comfortably connect the new chord to it and connect the new one to it.

opinions anyone?

Sometimes there's a place you can poke a wire in and release the terminal, other times it's crimped to a contact inside the switch. Don't try to take the switch apart, it's likely to go BOING! and you'll never get it back together right again. Just cut the wire off far enough from the switch that you can splice it using the method of your choice. Crimp butt splice, crimp cap, wire nut, solder and heatshrink, just whatever you're comfortable with that will fit in the space.

I know this is an old topic but it was still relevant and useful in 2021.
My Holmes pedestal fan died after running slower and slower over a period of months.
I took it apart and found that the "bearings" had too much friction in them. Basically, I should have added some 3-in-1 oil lubricating oil to the shaft that was running dry in the sleeves. The back bearing is easy to access, the front one is hidden inside the metal front cap, I would have had to just spray and pray with some spray lubricant (not WD-40).

Anyway, the motor was dead and not turning even after the load had been removed.
I cut up all the wires and finally noticed the little AUPO A4-F thermal fuse buried in the resin in the windings. Its showing infinite resistance (open).

If I had discovered this post earlier, I might have been able to save the fan but unfortunately, the circuits and wires are in absolute shreds !

I wanted to add a delayed Thank You - the device is indeed an AUPO A4-F 130C 2A fuse in the Holmes pedestal fan.

Yes, running slower and slower should have told you that something was seriously wrong and needed attention. A little light machine oil in the bearings would have gotten it going again no problem. Better motors even have little tubes you are supposed to put a few drops of oil in yearly.

Not long ago my daughter complained that her little fan wouldn't run.  I found the bearings dry.  So I put some oil on them and it spun nicely.  Plugged it in, and it worked fine.  I gave it back to her and later asked if it's okay.

She said it's perfect, and no longer makes the loud noise it used to make before it quit.
