Wayne Y Scarsdale , NY March 11, 2016 Poor heating noisy operation Removed front panel of dryer(thanks to repair videos covering this model) Inspect igniter as it wasn't as bright as expected. observe left worn roller causing poor rpm of drum and venting. I figured I may as well change left roller with roller axle and also right roller. In addition , I replaced the belt and the Fire box high limit and dryer gas valve coil kit as this dryer is 8 years old. Unit is now operational. The repair videos show you how to replace components but don`t show you how to diagnose possible causes. Overall , I like buying the parts from app because of the how to vids and the reasonable parts prices. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
