The videos were awesome and specific to the model of dryer I have. My dryer is ~14 years old with heavy use. We are the crazy cat people. I found two parts without continuity, one roller frozen and worn flat and the bulb was out. My wife had been complaining about the auto dry not working so I replaced those sensors too. In the end, I replaced everything that I thought could give me issues to include the belt. Getting to these parts is a chore and I only spent ~$70 more for the repairs. Now I have the used parts as spares in an emergency. The overnight delivery was spot on and a good value. To date the repair is holding and the dryer actually performs like it’s brand new. I did a deep cleaning too. Make sure you keep them clean and they last. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
