Possible Causes
Significant difference between lid and bottom temperature sensors, Poor thermal contact of one sensor, Faulty NTC sensor, Control board calibration error
How to Fix / Troubleshooting
Safety: Disconnect power and let the unit cool.
- Check for obvious overheating: Look for burnt food on the bottom of the pot or heating plate. Clean thoroughly.
- Inspect both sensors: Access the lid and bottom NTC sensors. Ensure they are firmly attached to their mounting points and have good thermal contact (no gaps or loose clips).
- Measure both sensors: At room temperature, measure resistance of lid and bottom NTCs. They should be similar (within a few kΩ). Replace any sensor that is significantly out of range or inconsistent.
- Check wiring harness: Ensure both sensor harnesses are intact and firmly connected to the PCB.
- If mismatch persists: The control board may be misinterpreting sensor values. Replace the main PCB if both sensors and wiring are confirmed good.
