Possible Causes
How to Fix / Troubleshooting
SAFETY: Unplug the microwave before inspection. Do not touch high-voltage components.
E06 usually indicates the control board is not receiving stable low-voltage power.
- Step 1 – External power check:
- Plug the microwave directly into a known-good wall outlet (no extension cords or multi-plugs).
- Avoid sharing the circuit with heavy appliances (kettle, heater).
- Step 2 – Visual inspection (unplugged):
- Remove the outer cabinet.
- Inspect the mains input area and line filter board for burnt components or loose connectors.
- Check the control PCB for obvious burn marks or bulging capacitors.
- Step 3 – Connector reseat:
- Firmly reseat the mains connector and low-voltage harnesses going to the control PCB.
If E06 persists, the control PCB or line filter board is likely damaged and should be replaced by a professional technician.
