John M New Orleans , LA August 15, 2015 Appliance: Model KITCHEN AID BLENDER PART # 9704230 (AP2930430) Drive coupler needed to be replaced Part(s) arrived in three days...we ordered two so we'd have a spare. Replacement was simple thanks to the repair video supplied by the Appliance Parts Pros. Entire replacement process took seconds. At first it seemed the coupler had not unscrewed - the shaft also moves clockwise...but indeed it had and threaded right off. I only wish the rest of life was so easy. Just needed a screwdriver and a hammer. Thank you. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
