Why is there smoke and a strong smell coming from my air fryer during use?

Smoke and odour during cooking are likely caused by food residue on the heating element (2) burning when the device heats up. The troubleshooting guide also notes that the frying basket must not be filled beyond the MAX marking, as overfilling can contribute to this issue. During first-time use only, minor smoke and odour from assembly materials on the heating element is normal and not a product fault.
