Oven enamel or liners flaking or discolouring prematurely.

Safety first: Allow oven to cool before inspection.

• 1. Stop abrasive cleaning: Use only non-scratch pads and approved oven cleaners.
• 2. Inspect for overheating signs: If multiple areas are heavily discoloured or warped, have the thermostat and overheat protection checked.
• 3. Replace liners: Many Rangemaster ovens have removable side or rear liners; replace these if the coating has failed.
• 4. Avoid direct flame contact (gas): Ensure flames do not impinge directly on enamel surfaces due to misaligned burners.
