How to Fix / Troubleshooting

Safety first: Immediately unplug the air fryer if you smell burning plastic or electrical odor. Do not continue using it until the source is identified.

Step 1 – Visual inspection of cooking chamber

  • After cooling, remove basket and pan.
  • Inspect the heating element area for melted plastic, foil, or food packaging that may have contacted the element.
  • Clean off any residue with a non-abrasive sponge and mild cleaner.

Step 2 – Check exterior and cord

  • Inspect the power cord and plug for melting or discoloration.
  • If damaged, replace the cord assembly.

Step 3 – Internal inspection (advanced)

  • Open the housing (unplugged).
  • Look for browned or melted insulation on wires, especially near the heater and control board.
  • Check connectors for signs of overheating (darkened plastic, brittle metal).
  • Inspect the control board for burned components.

Step 4 – Replace damaged parts

  • Replace any burned wiring harnesses or connectors.
  • If the control board shows burn marks or a strong electrical smell, replace the board.
  • Do not operate the unit until all damaged parts are replaced and wiring is secure.
