Air fryer occasionally sparks or pops near the heating element.

Safety first: Turn off and unplug the air fryer immediately if you see sparks. Allow it to cool before inspection.

Steps to address sparking:

• 1. Inspect heater area: Look for foil, metal skewers, or food debris touching the heating element. Remove any foreign objects.
• 2. Clean heater guard: If your Insignia model has a heater guard, remove and clean it thoroughly.
• 3. Check element surface: Inspect the element for cracks, pits, or burn marks that could indicate insulation breakdown.
• 4. Tighten connections: Ensure heater terminals are tight and not arcing at the connectors.
• 5. Replace heating element: If the element shows visible damage or continues to arc, replace it with a compatible Insignia heating element.

Warning: Do not use metal foil loosely in the air fryer; it can contact the heater and cause arcing or fire.
