Hi, I'm new here, but have read through a few of the threads.
My problem is that I got this baby bandsaw for free, the guy said it worked, but you have to start the wheel turning when you flip the switch, but it keeps going after that. I didn't get around to tinkering with it for most of the fall and winter, and tried it the other day and after opening the cabinet part that covers the blade and wheels, I flipped the switch and gave it a spin. It wanted to run, but the fuse, or whatever does this, shut it off and I had to push a reset button just at the top of the box. Several tries simply repeated the action.
Any clue how to fix it? I can't afford a "real" bandsaw just now, and would like to have this one work for little projects..

Seems like a bad accident waiting to happen.

I'd guess the fuse may be blowing because of the binding that's preventing the blade from spinning freely. Just a wild guess though. Good luck!

That kind of behavior is typical of an induction motor with a defective start capacitor or centrifugal switch. What kind of motor do you have?


Some photos of the bandsaw, inside and out, as well as the motor could be helpful.

i suspect a bad or dirty centrifugal switch. my bandsaw had the same problem, i had to smack the motor with a board to get the switch to close. smack your motor (power off) and listen for a faint click. pull the motor apart for a good cleaning/lube job

even with periodic compressor blow out, this pic is my table saw motor. for some reason the switch wouldn't close :redface:
cleaned up it works fine

Thanks, I have no clue what type of motor. I hesitated to open it so far because I didn't know what I'd be looking for. Now I'll take a look and see if I can do something about it.

YUCK! That table saw motor looks horrible--I really hope that if I find that in mine, cleaning it will solve everything!

Yeah, I wasn't too happy pushing that wheel, and almost relieved that I wasn't going to have to do it every time! I hope the suggestions here will solve the problem.

I didn't take pics of the saw blade area, its very clean, the wheels move smoothly and quietly--no clicking or grinding. I'm assuming the grey cylinder is the start capacitor.

yes, try replacing that first
also will the motor start up and run when it is laying out like that?

If you have an Ohmmeter or a continuity tester you can do a partial check of the centrifugal switch without opening the motor. When the motor is stopped the switch should be closed so you should read an Ohm or so between the Red wires. If you have sharp probes that will puncture the wire insulation you can do the test without removing the capacitor. Otherwise at least do the test before you attach the new capacitor if replacing it is the first thing you want to try.

Take the capacitor or the entire motor to a heating and cooling shop. There's not a furnace made that doesn't have a blower motor of some sort, so they will know what's wrong and they will also have a new start capacitor.

Great! I know a guy... :)

Would the fact that I plug the saw into a 100' heavy duty extension cord from the house have any relation to this issue?

I only plug one tool at a time and none of the others (table saw, drill, sawzall, etc) ever had an issue.

The socket in the house is on a circuit that only has my computer and router on, but not doing anything while I'm in the shed.

It's Alive!

I didn't try that yet, but I will. Thanks

I just tried to run it..successfully, laying loose on the workbench. A couple of times it wouldn't go, but I saw that the fan fins were touching the bench, when I moved it, it started and ran as long as I left it on. Here is a link to see it running:

Hmmm, watching it from behind the machine--which direction do the wheels go when turning to cut?

Goode News!

I managed to catch the electrical shop guy leaving early for Easter weekend, and he kindly went back in and got me a new capacitor for $10. I got home and put it all back together and it works like a champ!



It is still tough to start unless I spin the wheel a it, but it cut perfectly. I'm going to clean and lube it and see if that helps.



Once it's all set, I'll sell it, because I got a Craftsman 12" band saw yesterday that was my first choice in the search since it's the same one in my dad's workshop and I'm comfortable with it. It too needs a good cleaning, but it works right out of the gate. It came with a Porter Cable plunge router and a dovetail jig--like Christmas!



:smile2:Thanks for all your help guys!
