Richard T Minneapolis , MN June 24, 2014 Appliance: Model KHMC107YWH-0 Our microwave wave guide had disintegrated and when we contacted kitchen aid they said the part was no longer available We had a part number, found a compatible part on your website, ordered it and used it as a replacement. It was a very cheap part and a very easy fix for a couple of real amateurs! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
