Dryer problems... Kenmore 90 Series

Dryer won’t start, then starts on it’s own

History:
*About two weeks ago, heating quit
-Reset the thermal fuse and started heating fine.

**Three days ago, tried to start the dryer and it would not start/run
I was getting online to do some trouble shooting and within about 5-10
minutes or so, it started going on it’s own.

*** I checked the dryer by stopping and restarting 2 or three times. It did
start each time, but seemed to be an abnormal noise when pushing the
start button like a buzzing sound just as it started, but then seemed to operate normally.

Today, it’s doing the same thing, not starting manually, but then starting
on it’s own within a few minutes, runs for 5 minutes or so & shuts off.

Thanks for your assistance.
