Hi Coopah,
I sincerely doubt that the foot pedal itself is your issue.
I suspect, keep in mind, this is without seeing any photos or anything, that it's a bare / loose wire touching somewhere it shouldn't.
This wire -could- be in the pedal, but if it is, it's likely to be the cord that's the issue. The cord is very easily replaced, as in the articles that I posted above. (Sew-Classic)
Or it could be a heavily damaged connector, they often get broken putting the machine into the case.

-if- it's the cord set that has a broken wire, it's the easiest repair on the planet. Anyone can do it. It's not the delicate operation that someone on some site said it is. That's what I was saying by posting the links. It's a simple job, and as I talked about, AC current isn't concerned about which wire you put where in this cord, so if you can manage a screwdriver, and take it "slowly" the first time, your FW doesn't necessarily need to go on the shelf.
If you want a foot pedal that doesn't get warm when you use it, especially for slow sewing, then yes, change the pedal.
I think it's theoretically possible to have the pedal an issue IF the cushions on the bottom of the pedal are missing
and IF the cushion screws were sticking out and touching metal or the water that someone mentions in a tip of the month somewhere,
and IF there was something wrong inside the pedal causing that screw to be touching part of the mechanism that's carrying power. I really doubt that perfect storm is happening in your pedal. Again, assuming without pics.
I think it's far more likely that the thumbnuts where you connect the cord to the machine - the ones that you see when you turn the machine over to oil / grease the bottom - are hiding some bad wiring, or that the cord has cracks in it, and the wires are shorting.
My suspicion is that it's here, because usually it's got to be "touching" the item it's using for ground (in this case, the body of the machine), which is what's giving you the "buzz"
We've been looking at Alyce's pedal here:
http://www.quiltingboard.com/vintage...p-t223839.html
If you look at her excellent photo, you'll see the cordset at the top of the photo, attached to 2 screws. That's it. That's all that's required to change this cord. The hardest part is routing the new cord so it sits flat.
The cord can be had from Sew-Classic (
http://shop.sew-classic.com/Cord-Set...ers-SCE123.htm), or from Glenn Williams (I noticed you're in Florida, he is too -
http://pages.suddenlink.net/joyof301s/glenn.htm (Number 15) and his cord is less money than Jenny's (SC) and I've dealt with him. He's good stuff.)
I think best case scenario is that it's the cord. Then you have 2 options, in the short term, you can use the cord from MILs machine with yours, preserving her machine if you'd like (though I'd say run hers periodically anyway, or when you decide to use it down the road, it may want more TLC than just a light oiling), or you can replace the cord (an $8 - $10.29 item)
I suspect though that the issue is at the machine side. Here's why: The last machine I serviced for a cord / pedal issue, the symptom was "machine went berserk, I had to unplug it to stop it" - the same thing that Alyce complained of. Most often, a short between the machine and the pedal manifests this way. Yours could be the exception though.
I am going to make a suggestion - if this machine goes on the shelf, put a note with it, saying that it needs some electrical work. Better still if you know what it is, mention that too, or at least that it's a shocking little thing. This way, down the road, if the machine goes to someone else without being fixed, they don't have to relearn what you have here
Whew!! Another novel! Sorry about that. I should just write a book and have done with it.
