I've got a Delta ShopMaster bandsaw that I've had for years and don't use very
often. I was cutting some plywood today and noticed a burning smell and some
smoke coming from the motor. I turned it off, let it cool down, started it
again for a few minutes and it seemed fine, then there was a loud, electric
pop, lots of smoke came out from the switch, so I turned it off. I unscrewed
the switch, looked inside and didn't see anything burned, hot, etc. so I put
the switch back in, tried turning it on again and it made noise like it was
trying to run, but didn't move. I was able to move the belt manually, but the
engine didn't turn.
Is this saw dead? Does it sound like this is something I can troubleshoot and
fix?
Thanks!

Some years ago my table saw motor died. I took it into the small motor
repair shop and they disassembled it. It was an older capacitor start
motor and there was wood chip in a switch inside of the motor. Since
the switch could not close it cut off the capacitor that was necessary
to turn the motor over.

He showed me how to disassemble the motor to clean that area if I ever
had the problem again. Also as I am cleaning up the saw at the end of
a project vacuum out the ports on each side of the motor. I also
periodically oil the motor bearings.

If the winding in the motor are intact it probably can be fixed, so if
you can not find the problem I would recommend taking it to a shop
before discarding it.

I'd first suspect loose wiring at the motor end of the switch's wiring. Probably need to replace the switch and its wiring to the motor end.

To me, that popping sound was caused by wires touching, somewhere, not the motor itself.

The capacitor may have simply failed (catastrophically). Replace that
first. It shouldn't be that difficult.

Unless you are confident soldering components in the motor, follow Keith's advice and take it to a place that rewinds motors and let them trouble shoot it for you. It is a lot simpler and could be less expensive than probing around in an area you are not comfortable with.

It's a $100 bandsaw with a cheap little 1/3hp motor. Probably
cost more to take it in for troubleshooting than to simply replace the
saw.

Thanks to everyone for the replies!! I opened the switch housing and found the
blown capacitor!! Hopefully I can just replace that and save $160. However, I
started looking around for it and can't find a replacement anywhere that looks

What about this:

https://www.ebay.com/p/5021294937

You can also 20UF caps with higher voltage ratings (e.g. 450V) that will
work just fine. Typically, you want to at least double the expected
voltage.

You don't give the dimensions.

Google "20 microfarad rectangular run capacitor" and see if you get
anything that is close. Note that in general you can substitute a
capacitor with a higher voltage rating for one with a lower.

As opposed to the $3.99 ebay link I offered?

or 12.50 on Amazon?

https://www.amazon.com/ITACO-Generat.../dp/B018G8ADN6

Your choice...

Probably is a source, but site doesn't seem very easy to search.

Search for CBB61 and you get "We weren't able to find any results based
on your search entry."

Search for 20uF, and you get 16,605 results categorized by component type,
which you then need to drill down into. You really need to know what you
are looking for, like what *type* of capacitor (Tantalum, Aluminum, Ceramic,
etc.) before you can get very far.

On the other hand, search Amazon or ebay for *either* CBB61 or 20uF, and
you'll find an exact match for *both*.

Just 2 examples...

Agree with the searching on Digikey, if you know what you want not
that much of a problem. More for a electronics person who knows what
they want.

Locally, the best source in town is the HVAC parts guys -- they've got
most all motor capacitors for small single-phase motors. The motor shop
folks have the big stuff mostly; don't get many small motors.

Exactly. It's the best electronics search tool for engineers. The
rest of the industry search tools aren't even close. I probably order
from them a couple of times a month (just got an $1,000 order but
haven't been able to open it - locked out due to a WuFlu exposure in
building). If it's not at Digikey, in my desk, or a manufacturer's
sample, the possibility of a design-in is about nil.
