Took rotor off the machine, noticed the plastic teeth were rounded. So ordered a new one and also ordered a new position sensor since I already had it apart and changed that. Very easy to do, took less than a half-hour. Everything works great again. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
