Possible Causes

User selected keep-warm instead of cook, Partial failure of heater drive circuit, Firmware limiting power due to previous overheat, Faulty mode selection button

How to Fix / Troubleshooting

Safety first: Unplug the unit before any internal checks.

  • Confirm mode: Cancel the program and reselect a full cooking mode (e.g., Rice, Soup, Pressure Cook) instead of Keep Warm.
  • Panel function test: Press each button to ensure they respond correctly. If some keys do not respond, the keypad or touch panel may be faulty.
  • Power reset: Unplug for 10 minutes to clear any temporary firmware limitation.
  • Heater test (advanced): If the unit never reaches full heat, test the heating element and control relay/triac on the PCB. Replace the main control board if the heater drive is defective.
