Ninja multicooker shows E05 and will not start or continue a program.

Safety first: Disconnect power before any inspection. Internal sensor testing requires electrical knowledge.

• Power reset: Unplug the unit for 10–15 minutes to allow the control board to fully discharge, then plug back in and test.
• Visual inspection: Remove the inner pot and inspect the center of the heating plate area for a visible sensor probe or thermistor mount. Check for physical damage, burnt marks, or loose parts.
• Check for moisture: If the unit was recently washed or exposed to heavy steam, allow it to dry for 24 hours and retry.
• Advanced testing: A technician can remove the bottom cover and measure the thermistor resistance at room temperature and when gently warmed to confirm operation.
• If E05 persists: The temperature sensor or main control board will likely need replacement.
