My Repair & Advice
This is a Whirlpool WDG5700SWO Gas Dryer that is 7 years old. Fortunately, I have a Multimeter with a flex. temperature probe. Initially, I noticed the temperature would go up slowly reaching 212 degrees for about 5 minutes, then a loud click, go down to room temperature and stay there (not returning to heat). I suspected Cycling Thermostat issue. Ordered the Cycling Thermostat and Fuse as recommended by others. That did not fix the problem.
I then ordered the Hi - Limit cut off kit (Hi Limit Thermostat and the associated fuse) along with the set of coil solenoids and a new dryer belt. I was not looking forward to replacing the coils as it involved removing the drum. I regret that as I replaced Hi-Limit Thermostat with kit and it did not solve problem.
Finally, I got some help from my brother-in-law to remove the drum and replaced the coils along with replacing dryer belt. The idler arm bracket can be tricky. Take a picture before attempting to mess with it. It helps a great deal for reference. The coils apparently fixed the problem. If your symptoms are similar, don't hesitate to remove drum and replace the coil set which I understand over time need replacing anyways. AppliancePartsPro's saved me a technician call. Great Customer Support and the repair video's helped to make the job easier.
