Otto B Bristol , VA January 21, 2017 Verry loud shrill coming from unit Did a google search and found problem most likely the chopper assembly and that is what it was. Easily repaired although you have to be somewhat of a contortionist. Ordering part AppliancePartsPros was easy and delivered as promised 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
