Oven racks are difficult to slide or make scraping noises

Safety first: Ensure the oven is cool before handling racks.

• Clean racks and supports: Remove racks and clean them and the rack support rails with warm soapy water. Remove baked-on debris.
• Inspect for warping: Replace any racks that are bent or warped.
• Lubricate glide racks: For Monogram glide racks, apply a small amount of high-temperature food-safe lubricant to the glide surfaces if recommended by the manual.
