Excessive steam or smoke escapes from vents during normal cooking.

Safety first: Ensure good kitchen ventilation. If smoke is heavy or dark, unplug the fryer.

Steps:

• 1. Clean thoroughly: Remove grease from the basket, pan, heater guard, and interior surfaces.
• 2. Adjust cooking method: For very fatty foods, reduce temperature slightly and extend cooking time. Empty excess fat from the pan between batches.
• 3. Check vents: Ensure exhaust vents are clear and not blocked by walls or objects.
• 4. Use appropriate oils: Avoid adding oils with low smoke points (e.g., unrefined oils) at high temperatures.

Warning: Persistent heavy smoke can indicate overheating or grease ignition risk; inspect heater and wiring for damage.
