Possible Causes

Bottom or lid sensor reading too high, Poor contact between pot and heating plate, Pressure leaks reducing effective cooking temperature

How to Fix / Troubleshooting

Safety first: Unplug and cool before internal checks.

  • Check pot and plate: Ensure the inner pot bottom is clean and flat, and the heating plate is free of debris.
  • Inspect lid gasket and valves: For pressure programs, ensure no steam leaks and that the gasket and valves are in good condition.
  • Sensor check: If recently serviced, verify that correct Redmond sensors were installed. Replace any suspect NTC sensors.
  • Test with water: Run a test with a known amount of water and measure temperature during cooking (using an external thermometer) to confirm underheating.
