How to Fix / Troubleshooting
Steps:
- 1. Clear program: Press STOP/CANCEL and then try re-entering the cooking time and power level according to the user manual.
- 2. Power reset: Unplug the microwave for 5–10 minutes to reset the control board. Plug back in and set the clock if required.
- 3. Test basic function: Try a simple manual cook (e.g., 30 seconds on full power). If Err appears only on specific auto menus, the issue may be software-related.
- 4. Inspect control panel: Check for stuck keys or damaged keypad that might be sending invalid signals.
If Err appears on all functions after a reset, the control PCB may need replacement by an authorized service center.
