Lisa U Roseburg , OR April 23, 2016 Whirlpool duet dryer wouldn't start Replaced the thermal fuse and belt switch. Fairly easy fix, just annoying to get to the parts that needed replaced. I have no prior experience with dryer repair and am a 90lb girl.. So anyone can do this if they try. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
