How to Fix / Troubleshooting

Safety first: Unplug the cooker and allow it to cool for at least 30 minutes.

  • Check placement: Ensure the cooker is not placed in a confined space or under low cabinets where heat accumulates.
  • Clean vents: Inspect and clean all side and bottom ventilation slots with a soft brush or vacuum.
  • Internal fan (if present): Some Hisense models have a small cooling fan. Remove the outer cover and verify the fan spins freely and is not obstructed. Replace if seized or noisy.
  • Ambient temperature: Avoid using the cooker in very hot rooms or near other heat sources.
  • Re-test: After cooling and cleaning, run a low-temperature program to confirm normal operation.
