Possible Causes
Drifted temperature sensor, Faulty thermostat or control board, Poor contact between inner pot and heating plate, Warped inner pot bottom
How to Fix / Troubleshooting
Safety first: Use caution when checking temperatures; surfaces may be hot.
- Ensure proper pot contact: Verify the inner pot sits flat on the heating plate with no wobble. Replace the pot if the base is warped.
- Avoid overfilling: Follow Ninja fill lines; overfilling can affect temperature sensing and cause uneven cooking.
- Test with water: Run a BOIL or SAUTÉ function with a measured amount of water and use a food thermometer to compare actual vs set temperature.
- Persistent inaccuracy: Indicates sensor or control board calibration issues. Professional recalibration or board replacement may be required.
