Update on my GFI issue. Recap: Jointer kept popping GFI outlet. Got lots
of good advice here but life got in the way and I wasn't able to resolve t
he problem until after Christmas.
I pulled the motor out of the unit. I cleaned it but it actually had very
little dust buildup. I connected it (without the original switch) to a GFI
circuit and it ran without any problem.
I then took the switch apart. It was set up so it broke the connection of
both the black wire and white wire. I bought the jointer set up for 120 VA
C and ran it that way but I guess the switch was wired that way so you coul
d re-wire for 240 VAC. The switch had two contactors (one for each wire) t
hat looked like the points I used to have in my car back when I understood
how to work on my car. They were both in bad shape. I filed and sanded th
e contacts with the intention of reusing the switch but, when I attempted t
o reassemble the switch, I broke it enough to make repair impractical. Thu
s I replaced the original switch with this one (actually, the same switch m
After a little extra work (switch didn't fit in a standard electrical box j
ust as the reviews warned), I was back in business.
Bottom-line: The old switch caused the GFI outlet to pop.
Thanks again for all the input from the "rec",

ker? Also, what would I look for with respect to the cause. I bought the
jointer new 8 or 9 years ago and it has been lightly used.
