Food cooks unevenly; some areas are burnt while others are undercooked.

Safety first: Unplug and cool the unit before any internal inspection.

• Do not overload: Cook in smaller batches and avoid stacking food too high. Air must circulate around each piece.
• Shake or rotate: For fries and small items, shake the basket halfway through cooking. For larger items, flip or rotate them.
• Check tray alignment: Ensure the crisper tray sits flat and locked into the basket so air can flow underneath.
• Clean vents: Make sure rear and side vents are free of grease and dust.
• Sensor check: If temperature swings are extreme (very hot then cool), inspect and, if necessary, replace the NTC temperature sensor harness.
