E14 error appears on some Ninja models with integrated probes or smart thermometers; cooking cannot start.

Safety first: Unplug the unit before inserting or removing any probe accessories.

• Step 1 – Remove probe: If a food probe is connected, unplug it from the jack and inspect the plug for grease or moisture. Wipe clean and dry thoroughly.
• Step 2 – Inspect cable: Check the probe cable for cuts, kinks, or melted sections. A damaged cable can short the sensor circuit.
• Step 3 – Try without probe: Some models allow operation without the probe. Remove the probe completely and attempt a standard air fry cycle. If E14 clears, the probe is likely faulty.
• Step 4 – Clean probe jack: Use a dry cotton swab to gently clean the probe jack on the unit. Do not use liquids inside the jack.
• Step 5 – Replacement: If E14 only appears when the probe is connected, replace the probe. If it appears even with no probe, the control board's probe circuit may be faulty.
