Multicooker heats too much; food burns at the bottom even on normal programs.

Safety first: Unplug and allow to cool before inspection.

• Check cooking habits: Ensure sufficient liquid is used and food is stirred when appropriate. If burning occurs even with adequate liquid, suspect hardware.
• Inspect sensor placement: Verify that the bottom sensor is firmly attached to the heating plate and not displaced.
• Test NTC: Measure the NTC resistance at room temperature and compare to specification or to a known-good sensor. Replace if out of range.
• Check thermostat: If a bimetal thermostat is present, ensure it opens at the correct temperature (requires heating and monitoring continuity). Replace if stuck closed.

If overheating persists after sensor and thermostat replacement, the control board may require replacement.
