My dryer is a Kenmore model no. 110.96588210. It still works - but it
exhibits the following problem:

After one drying session, I need to wait for it to cool down before I
can restart it again.

This problem is very consistent: If the dryer is sufficiently cool, it
will start and run till completion or till.. it gets too hot and then
stop (before completing the session).

I did notice that starting it is not as easy as it used to be: It
seems that the drum has a hard time rotating (mechanically speaking) -
and the motor sounds some noise of trying to rotate something that is
mechanically stuck. However, if it is cool enough, it will start after
a 2-3 seconds.

I suspected the support rollers, but when I took the dryer apart, they
looked all even (as if they are new). Each of them rotates freely on
its shaft, and when the drum is mounted and rotating I verified that
all of them rotate. So, does that rule out the rollers?

Also, if the rollers are gone, why is it temperature dependent?

I could have bought new rollers and see if they solve the problem, but
it's a $50 expense which I would like to avoid if not necessary. It
could turn out to be the motor (?) or some thermostat... How do I know
which?

I did notice that one of the shafts (the rear right one) is worn
out... could this be the problem? How can I measure the "freedom" of
those support rollers rotation?

Thanks for any tip or idea you can offer!

P.S. I searched repairclinic.com for possible tips or advice on my
problem, but I couldn't find anything that addresses my particular
case.

Sounds like one of the overheat sensors is shutting it down. They are
located in the ductwork that's under the drum -- and eventually
channles the hot air outside. If lint has built up around the sensor,
it'll shut down. By the same token, go outside and see if your dryer
vent is clogged. That'll cause the machine to overheat as well.
