Possible Causes

Incorrect firmware calibration, NTC sensor misreading at low temperatures, Stuck relay cycling too slowly, Poor thermal contact between pot and sensor

How to Fix / Troubleshooting

Safety first: Unplug the cooker before internal inspection.

Steps to mitigate overheating on keep-warm:

  • 1. Add liquid: Ensure there is sufficient liquid in the pot before activating keep-warm.
  • 2. Stir before warming: Stir food to distribute heat and prevent localized burning.
  • 3. Check sensor and plate: Clean the heating plate and sensor, and verify good contact with the inner pot.
  • 4. Test with water: Run keep-warm with only water and measure temperature after 1–2 hours. If it is significantly above typical food-safe holding temperatures (around 60–75°C), the control system may be faulty.
  • 5. Replace NTC or PCB: If misregulation persists, replace the bottom NTC sensor. If that does not help, the main control board may require replacement.

As a workaround, limit keep-warm duration or use a lower-temperature manual mode if available.
