Oven racks are difficult to slide or make scraping noises.

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

• 1. Clean guides: Remove racks and clean the side supports and rack surfaces with warm soapy water. Dry thoroughly.
• 2. Inspect racks: Check for warping or bent sections. Replace damaged racks.
• 3. Lubricate telescopic racks: If your La Cornue oven has telescopic racks, apply a small amount of high-temperature food-safe lubricant to the moving parts as recommended by the manufacturer.
• 4. Avoid overload: Do not exceed the weight rating of racks to prevent bending.
