Oven racks are difficult to slide or bind during use.

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

• Step 1 – Clean racks and rails: Remove racks and clean both racks and side rails thoroughly with degreaser. Rinse and dry completely.
• Step 2 – Inspect for warping: Place racks on a flat surface to check for warping. Replace any that are bent.
• Step 3 – Check cavity rails: Inspect the oven’s side rails for chips or rough spots in the porcelain. Lightly smooth sharp edges with fine sandpaper (avoid exposing bare metal excessively).
• Step 4 – Use high-temp lubricant (optional): Apply a very thin layer of high-temperature food-safe lubricant to the rack contact points if recommended by Zline.

Note: Do not use regular oils or greases; they can smoke or burn in the oven.
