Started testing continuity on all the thermostats. No problem there. Then I tried replacing the coils. Still had the same problem. I didn't realize that my igniter was bad until I tested its continuity. Ordered and installed the new igniter ... problem solved. Tip: Learn how to use a multi-meter. This is my go-to site for appliance repair. The web site, the install videos, the ability to chat with a technician are all great! I have repaired 2 dryers and an ice maker in a refrigerator using this site. Saved me lots of $$.
