Help, please...
Kenmore "Ultra Fabric Care" gas dryer,
"Heavy duty 80 series",
Model #97586210 75862...

Sometimes it works, sometimes it doesn't.

Push the Start button, and...

Sometimes you hear just a Click. Nothing more.

Sometimes you hear the Buzz for a second, then a Click, and it starts
and runs like normal.

Sometimes you hear a loud Buzz for as long as you hold the button
down.
It doesn't start.

Now, after it starts and is running normally,
it Stops all by itself after 5 minutes,
even though the timer is set at 60 minutes.

I removed the Front of the dryer, and unhooked the drive belt to see
what's happening...

The Click comes from the Solenoid in the Front/Left side where the gas
enters the burner.

The Buzz comes from near the motor, in the Rear/Right side.

What's happening here?
How to fix this thing?

Thanks in advance, people.
