Your model has thermostats, thermal cutoff and thermal fuse. Unplug the dryer and check each one for continuity. The one(s) that are open have to be replaced.

Note: If any of the above are open it is a sign there is inadequate airflow through your dryer. When you have it open be sure and get all of the lint and any other debris out of the vent system. Compressed air is good if you have it.

If you have continuity in all of the above, post and let us know. You probably have a gas burner issue then.

Good luck, and let us know how it turns out.

You should be able to access these parts by removing the rear panel.

You are going to need an electrical meter that measures continuity/ohms, and if you don't have one or are not familiar with checking continuity I suggest you get a friend over with his/her meter.

Good luck
