Strong burning or electrical smell when oven is in use, sometimes accompanied by smoke.

Safety First: If you smell burning plastic or see smoke from control areas, turn off the oven and breaker immediately.

• Initial burn-in: For new Café ovens, run an empty bake cycle at 400–450°F for 30–60 minutes with good ventilation to burn off manufacturing residues.
• Clean spills: Once cool, inspect elements and oven floor for spilled food or cleaner. Clean with a non-abrasive cleaner.
• Inspect wiring: Remove the rear panel and check the terminal block, element connections, and harnesses for signs of melting or charring. Repair or replace damaged parts.
• Do not ignore electrical smells: If wiring damage is found or smell persists from the control area, discontinue use until a qualified technician inspects the main control board and wiring.
