I watched the video, tested the part that I thought it may be, then ordered the part. The part was delivered and I re watched the video again. I unplugged the dryer then followed instructions from the video and was able to get to the thermal limiter to replace it. I put the dryer back together, plugged it in and it worked. I was very excited that I was able to fix the problem for less than $20.00. The videos are great to learn how to fix appliances My husband was surprised when he got home and pleased that he didn't have to buy a new dryer.
