Possible Causes
Incorrect temperature calibration on control board, Drifted bottom NTC sensor, Poor heat distribution due to warped pot, Firmware bug in specific model series
How to Fix / Troubleshooting
Safety first: Unplug before internal checks.
- Test with water: Measure water temperature during keep-warm with a kitchen thermometer. If significantly above typical 60–75°C, there is a control issue.
- Check pot and plate: Replace a warped inner pot that may cause localized overheating.
- Replace sensor: Install a new bottom NTC sensor if readings are suspect.
- Board/firmware: If the issue persists, the main control board may need replacement or firmware update via Polaris service.
