My circa mid-70's Craftsman TS will sometimes - very, very rarely - exhibit the same symptom. A long time ago I read something about dust getting into the internal start switch preventing it from making. Rapping it with a rubber mallet clears it and it starts right up.

I've probably only had to to do it half a dozen times in 20+ years, but it worked every time. Just do it safely, since you might not be concentrating on the blade at the time.

My 14" Delta bandsaw has the same issue, once a month or so. Dust collection is not hooked up to it. Sometimes tapping the motor will free up the (dust covered) contacts. Sometimes, blowing it out with the air hose, through the rear vents, works, when tapping alone doesn't. Half the time, I have to open the motor housing and blow the dust out.

If that doesn't work, it probably needs a new starting
capacitor.

But - before you do either of those things, unplug it and
make sure the blade can be turned by hand. If something
is jamming it, or the motor bearings have seized, no amount
rapping with mallets will help.

Your motor is a capacitance start motor

http://vintagemachinery.org/pubs/222/1561.pdf

Many years ago my craftsman capacitance start motor stopped working.
The man at the small engine repair service showed me how to disassemble
it and clean the inside.

I periodically take the motor apart and remove all of the small wood
chips in the started circuit for the motor. These wood chips were
preventing the motor from starting properly

Now in addition to the disassemble every 4 or 5 years, I carefully
vacuum the openings on the motor every time I use the saw.

Thanks I'll try hitting it. There is dust in the motor.

That is only temporary. Try clean it out as suggested.

Breaking the motor open is scarry but is quite simple. Just make sure
no parts are left over.

Cleaned the motor with shop vac motor is working again. Hopefully until I get a new table saw, thanks again.

It was about 15 years ago when I had the problem and was shown how to
disassemble the motor to do a deep clean. I have had no problems
since. As it was explained to me wood chip get into the contacts that
??open/close?? in the start circuit, preventing the motor to start.

As long as the contacts have not been damaged, you are good to go, until
the "new saw bug" bites you. At that time the only way to resolve the
problem is to buy a new saw.

[DerbyDad03]

Meanwhile, on the "alternative medicine" front...

Mentioning to SWMBO that you are planning to buy a new saw has been shown to be a cure for the infection caused by the "new saw bug".

[hubops]

My understanding of this condition is that the centrifugal switch
gets gummed up with sawdust - so the capacitor boost isn't
boosting when trying to start ..
Hitting it with a hammer wouldn't be my recommendation -
but a good vacuum job & shots of air will often do it.

I'm not sure anyone recommended a hammer, per se. I believe a "rubber mallet" was the suggestion. So much gentler...

[cl...@snyder.on.ca]

Had a similar situation when my trusty TomTom GPS died over the
holidays. I got a case of "new gps bug" and SWMBO said "can't you fix
it? you fix everything else". I was kinda jonesing for a voice command
unit with a 6 inch screen (they are pretty proud of those, judjing by
the price) - but I tore into the old one when we got home, and
wouldn't you know it - I fixed it.

Guess I'll need a worse case of the "bug" before I get a new one - - -

We had an old dryer, that after fixing it for the umpteenth time, I
decided that we should replace it. When it died, it told my wife we
were going to go get a new one. She said just take a minute to look at
it. After replacing the $2 resistor it worked fine for about 5 more years.

[DerbyDad03]

Have you added up the repair costs? Would a new dryer have been worth it?

In the past 8 years I've replaced the gas valve solenoids twice and just last weekend I replaced the thermal fuse (and the high limit thermostat as a safety measure).

Maybe $75 total in 8 years and the opportunity to clean and inspect the dryer inside and out.

It would take quite a few more repairs to even come close to the cost of new dryer. I will not be defeated! ;-)

Get one with a TEFC motor. Less likely to get junk in it. My five
major tools all have them. The belt sander I use for sharpening does
not, and I worry about it.

You may consider putting together some sort of dust shield. All it has to
do is direct the dust away from the motor while not cutting off air flow to
and around it. I have one on my little lathe, as the motor would be
covered in chips and dust in just a short time. All it is is a piece of
plexiglass in a wood frame.

If your motor has open vents for cooling, like mine does, you can slow
this down a lot my covering the vents with a piece of your wife's,
girlfriends, or your, panty hose/nylon stocking. It lets air circulate
and filters out the sawdust. Been working for me for many years.

The only question left which begs to be asked Jack, is what size panty hose
do you wear, which works on your motor?

I have a copy of the original documentation for the motor and can send a
copy.

If you have never done it you may have to do a little more that blow it
out. On the one end of the motor there is a metal cover. When you
remove this you can clear the switch that prevents the motor from
turning over.

You can CAREFULLY remove the bolts that hold the three parts of the
motor together and clean it thoroughly.

If you are new to the your house or have not checked your circuits, that
may be the cause of your problem. Per the original manual for the
motor it should be on a 20 amp circuit. While you may get it started on
a 15 amp circuit, you will periodically have the problem you are
experiencing.

In my 8 year old house the only 20 amp circuit in the garage (my shop)
is the one in the ceiling for the garage door opener.

Sorry about responding to this post, I did not read the date which is
nearly 3 years old.

[DerbyDad03]

No problem. Good advice is timeless.
