How to Fix / Troubleshooting
Safety warning: Treat E30 as a serious safety-related error. Do not continue to use the microwave until the cause is identified.
- Step 1 – Power reset: Unplug the microwave for 10 minutes, then reconnect. If E30 clears and does not return, monitor operation closely.
- Step 2 – Door system check: Inspect and test all door interlock switches and latch components as described for E01/E13.
- Step 3 – Overheat check: Ensure vents are clear and that cooling fans operate correctly. Check thermal cut-outs for proper function.
- Step 4 – Professional diagnosis: If E30 persists, have an AEG service technician run diagnostic mode to identify the underlying subsystem fault and replace the necessary parts.
