Greta M San Pablo , CA September 25, 2015 The coupling needed to be replaced on a kichenaid blender This simple blender coupling repair took me two minutes to repair and it save me a trip to the repair shop. I watched the Appliance Part Pros video online, it was very helpful in doing the repairs to my blender. Thanks. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
