Possible Causes

Missing or damaged internal thermal insulation wrap, Loose inner pot support allowing heat to escape, Overpowered heating element cycling incorrectly, Blocked ventilation slots

How to Fix / Troubleshooting

Safety first: Use caution when touching the cooker during operation. Unplug and cool before disassembly.

  • Check placement: Ensure the cooker is not placed in a confined space that traps heat.
  • Inspect ventilation: Clean any dust or grease from ventilation slots on the base or sides.
  • Internal insulation (advanced): Remove the outer shell to inspect any fiberglass or foil insulation around the inner pot housing. Replace or reposition if missing or displaced.
  • Check for gaps: Ensure the inner pot support ring and top cover fit snugly, minimizing direct heat paths to the exterior.
  • Monitor operation: After reassembly, run a short cycle and periodically check exterior temperature. Some warmth is normal, but it should not be scalding.

Warning: Damaged insulation can pose a burn risk and may affect internal component life; address promptly.
