Possible Causes

Disabled keep-warm setting, Faulty keep-warm relay on PCB, NTC sensor misreading temperature, Firmware glitch

How to Fix / Troubleshooting

Safety first: Unplug before internal checks.

  • Check settings: Confirm that the keep-warm function is enabled in the menu and not manually turned off at the end of cooking.
  • Reset cooker: Perform a power reset by unplugging for 5–10 minutes.
  • Test with short cycle: Run a quick cook program and observe whether the display switches to keep-warm afterward.
  • Inspect sensor and relay: From the bottom, check the NTC sensor and listen for a relay click when keep-warm should engage; absence may indicate a failed relay.

If keep-warm never engages despite correct settings, the main PCB or sensor may need replacement.
