Using my trusting Ohm meter and the AppliancePartsPros.com video I discovered the dryer thermal fuse had blown. Since I had the dryer apart I replaced the thermal fuse and the thermistor. Altogether well under the price for a service call ($80). The website, access to manuals and IPBs make finding the right part easy. Oh, it does help to keep that exhaust clean. Found a bird nest in mine. Could have the reason I needed a part.....
