I have a Kenmore 300 series dryer, purchased on 10/1/07, and the dryer will work, but only blow cool air, and the timer doesn't not work, I was wondering if there was some sort of reset switch on the dryer, or is there a fuse that needs to be replaced?

If the timer is set to the Auto - More/Less Dry it will not advance if there is no heat.

Check to see if the igniter is glowing on startup.

Get back to me on it.
