I have a Kenmore Gas Dryer..unknown how old.

When setting it to dry it runs right up to the point of stop, but continues
to run (drum turns) and won't stop (The indicator on the dial stays in same
spot).

The other thing is that the dryer fails to heat up. When I start the dryer,
the drum turns, and I hear the clacking of the gas valves, but I don't see
the glow of the igniter. (Not set on fluff or air dry).

Are these problems related to one another?
Any help would be greatly appreciated..
TIA..
