I found the exact symptoms listed here and bought the recommended replacement rotor position sensor. It took me longer to get the dryer taken down and the washer out than it took to actually replace the part. They even have a video on here showing me how to do it. It was a super easy $22 fix for a $700 machine. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
