Oven emits strong burning smell or smoke on use, especially first use or after long idle period

Safety: If smoke is heavy or smells electrical (acrid), switch off immediately and investigate. Ensure good ventilation.

• Initial burn-in: For new or recently repaired ovens, run empty at 220–250°C for 30–60 minutes with good ventilation to burn off residues.
• Clean cavity: Remove heavy grease and food deposits from the cavity and elements using an oven-safe cleaner (avoid spraying directly on elements).
• Inspect wiring: If the smell is electrical, remove the rear cover and check for discoloured or melted wires. Repair or replace damaged wiring and locate the overheating cause.
• Check door seal: Ensure smoke is not escaping excessively due to a failed seal.
