Your website had a video that was not for my model dryer. Fortunately I found another site with a video for my model. It turns out the appliance technician we paid over $100, made a repair that replaced the thermister with a thermal fuse. Turns out the thermal fuse was fine but the thermister had gone bad. I replaced the incorrect part with a new thermister. I also replaced the sensor bars. Your video shows only one sensor bar being replaced without indicating how to know which sensor bar was bad or if both should be replaced. I replaced both and the dryer is now working just fine.
By the way, I'm not criticizing your videos. The video on another site that showed how to replace the termister on my model dryer had you dismantling practically the whole dryer to replace the thermister. Your video showed a much simpler technique. It would be helpful if you mentioned the model in your videos.
