Air fryer emits a burning plastic or electrical smell during use.

Safety first: If you smell strong burning plastic or see smoke from the housing (not just food), unplug the air fryer immediately and do not continue using it until inspected.

Steps to investigate burning smell:

• 1. Differentiate food vs. electrical smell: A light odor is normal for new units or after heavy cooking. A sharp, chemical, or plastic smell suggests electrical issues.
• 2. Inspect the heater area: After cooling and unplugging, remove the basket and look at the heating element. Clean off any heavy grease or food residue that may be burning.
• 3. Open the housing: Remove the rear or bottom cover to inspect wiring around the heater, fan motor, and control board. Look for melted insulation, darkened connectors, or scorch marks.
• 4. Check heater terminals: Ensure the heater spade connectors are tight. Loose connections can arc and overheat, causing a burning smell.
• 5. Inspect the fan motor: Smell near the fan motor. If the odor is strongest there and the motor housing is discolored, the motor may be overheating and should be replaced.
• 6. Replace damaged parts: Replace any burnt wiring harnesses, connectors, or components. If the control board or heater area shows significant heat damage, replace the affected assemblies.

Warning: Do not continue using the air fryer if any internal wiring or plastic parts are visibly melted. This is a fire hazard.
