James R Bucyrus , OH January 13, 2017 Appliance: Model HB-P100N30AL-S3 Missing part I bought a closeout display microwave and had already ordered a turntable roller through Appliance parts. I later realized there was a waveguide cover (shown on parts list) missing. I searched using the pictures provided and found one the exact height and width. The 1-inch squares used in parts descriptions are excellent for sizing what you need, particularly when them manufacturer is unknown. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
