After researching my dryer problem, I replaced the high limit thermostat and thermistor since they are the two most common issues with the "no heat" problem.
The first time, it lasted two loads of laundry, and I was right back to the same problem.
I called the tech support line and talked to Michael. APP replaced the high limit thermostat at no charge.
This time, the repairs lasted a few loads of laundry before quitting again.
My wife was ready to buy a new dryer, but i ordered all three thermostats - high limit, cycling, and the thermostat.
After what seems like 65 times taking my dryer apart, it works like it was new.
The parts are inexpensive, so I would recommend replacing all three thermostats with the thermistor the first time you take your dryer apart. Work on it one time. Replacing them all is cheap insurance. If something isn't right, APP is super easy to work with.
