David D Parker , CO June 02, 2016 Appliance: KitchenAid Microwave Hood Combination 1.8 Cu. Ft. KHMS1850SBL1 Kitchenaid Microwave Khms1850sbl1: Broken tabs on grill vent portion of microwave/cooktop hood. How to replace Grill-Vent. Part arrived sooner than I would have expected. Unfortunately, it was bent. Called customer service and they had a replacement out that same day. Part fit perfectly and color (black) was a perfect match. Installation of replacement part involved nothing more than two phillips screws. I'd order from these folks again. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
