Possible Causes
How to Fix / Troubleshooting
Safety: Always unplug the microwave before inspecting the power cord or internal connections.
External checks:
- Plug the microwave directly into a wall outlet; avoid extension cords or multi-plug adapters.
- Test the outlet with another high-power appliance to confirm it delivers stable power.
- If lights dim significantly when the microwave starts, consult an electrician about the circuit capacity.
Internal checks (qualified):
- Inspect the power cord for cuts, burns, or kinks; replace if damaged.
- Check the mains terminal block and line filter board for loose screws or burned connectors.
- Measure the low-voltage outputs from the control board's power supply section; if unstable, the board may need replacement.
If E09 recurs despite a known-good outlet and cord, the internal power supply or control board should be serviced by a technician.
