I got online at AppliancePartsPros.com and found my make and model and low and behold, the main causes of dryer not heating were spelled out, and an explanation of each and how a bad thermistor can cause thermostat to fail, along with heaing element as a possibility. I decided to it, ordered all 3 on a Friday, and received them on Monday. The videos made the install very straightforward, and once everything buttoned up, the dryer worked perfectly. Many thanks to Appliance Parts Pros. You are indeed a great company.
