I originally posted this question a couple of years ago, but the dryer
was put in storage, and I never got to the repair. Now it's back again
(long story), but unfortunately, I've lost all the responses with
suggestions of what to check.

Anyway, I have an 18 year old Maytag gas dryer (model number DG 482 W)
that has suddenly started to cycle on and off in roughly 30 second
intervals. I don't think it's a heat buildup problem since it starts
cycling immediately after it's turned on. I've checked the ducting,
and everything is clear. The flame is a nice, bright blue.

Any/all suggestions are appreciated.

I hope http://www.repairclinic.com/0047_8.asp can be useful...

Good luck.
