Possible Causes

Incorrect temperature calibration, Faulty bottom temperature sensor, Firmware bug in keep-warm control, Poor heat distribution due to warped pot

How to Fix / Troubleshooting

Safety first: Avoid leaving the cooker unattended for long periods if it is known to overheat on Keep Warm.

  • Reduce duration: Manually limit Keep Warm time and stir food occasionally to prevent sticking.
  • Use more liquid: For rice and grains, leave a bit more moisture to compensate for evaporation.
  • Test with water: Run Keep Warm with water only and measure temperature with a kitchen thermometer. If it boils, the control is faulty.
  • Service recommendation: Overheating on Keep Warm usually indicates sensor or firmware issues; contact an Oursson service center for diagnosis.
