Possible Causes
Faulty temperature selector knob or encoder, Broken potentiometer on the control panel, Loose connection between the temperature control and the main board, Firmware error in the control board
How to Fix / Troubleshooting
Safety: Disconnect power.
Check Temperature Control:
- Remove the temperature knob and front panel to access the temperature selector (potentiometer or encoder).
- Inspect for physical damage or a broken shaft.
- Test the potentiometer with a multimeter for smooth resistance change when turned. Replace if readings jump or drop out.
- Ensure the connector from the selector to the main control board is firmly seated.
- If the hardware is fine, a main control board firmware or ADC fault may be present, and the board may need replacement.
