Rice or food is consistently overcooked, scorched at the bottom, or burns even when following Aroma recipes.

Possible Causes

Drifted bottom NTC sensor reading low, Poor thermal contact between sensor and plate, Control board calibration drift, Inner pot coating damaged causing sticking and hot spots

How to Fix / Troubleshooting

Safety first: Unplug and cool the unit before inspection.

  • Verify measurements: Confirm you are using the correct water-to-rice ratio recommended by Aroma and not exceeding the max fill line.
  • Inspect inner pot: Check for worn or scratched nonstick coating. Replace the inner pot if the coating is badly damaged.
  • Clean sensor area: Clean the heating plate and ensure no residue is insulating the sensor area.
  • Check sensor mounting: From the underside, verify that the bottom sensor is firmly attached to the plate. Reseat or reclip if loose.
  • Test different modes: Try a different cooking mode (e.g., White Rice vs. Brown Rice). If all modes overcook, the sensor or control board may be out of calibration and require replacement.
