Display shows E14 and the unit will not enter certain modes (e.g., Air Crisp or Bake/Roast on combo models).

Safety first: Ensure the unit is unplugged before inspecting lid sensors or hinges.

• Confirm correct lid: For Ninja Foodi-style multicookers, use the pressure lid only for pressure/steam/slow cook and the crisping lid for air fry/bake/roast. E14 often appears when the wrong lid is detected.
• Open and close lid fully: On hinged crisping lids, open the lid fully until it locks, then close firmly to ensure the lid sensor engages.
• Inspect lid magnet/sensor: Look for a small magnet in the lid edge and a corresponding sensor area on the body. Clean any grease or debris that might interfere with detection.
• Test other modes: Try a function that uses the currently installed lid. If that works but others show E14, the lid detection circuit may be partially faulty.
