Caple oven side rails or telescopic runners do not slide smoothly; shelves stick or tilt.

Safety first: Allow the oven to cool before removing shelves.

• Remove and clean: Take out all shelves and side rails. Soak in warm soapy water and scrub off grease and carbon deposits.
• Inspect for damage: Check rails and runners for bending or broken clips. Replace any damaged components.
• Reinstall correctly: Fit shelves and runners according to the Caple manual, ensuring they are fully engaged in the side supports.
• Lubrication: Do not use standard oils or greases inside the oven. If runners are worn, replace them rather than lubricating.
