Oven produces excessive smoke or burning smell during normal baking (not self-clean).

Safety first: If smoke is heavy, turn off the oven, open windows, and avoid opening the door fully until smoke subsides to prevent flare-ups.

Steps to check and correct:

• Inspect interior: After cooling, remove racks and inspect the oven floor, walls, and elements for heavy grease or spills.
• Clean thoroughly: Use a non-caustic oven cleaner or a baking soda paste to clean affected areas. Avoid spraying directly on elements; wipe them with a damp cloth only when cool.
• Remove foil liners: Do not line the oven bottom or racks with foil; this can trap grease and block airflow.
• Burn-off cycle: For a new oven, run a 450°F cycle for 30–60 minutes with good ventilation to burn off manufacturing residues.

When to call a technician: If you see flames inside the oven or smell electrical burning (plastic or wiring), turn off power and call for service immediately.
