How to Fix / Troubleshooting
Safety warning: Inverter-based microwaves use high-frequency high-voltage circuits that are extremely dangerous. Only trained personnel should service the inverter module.
User-level checks:
- Unplug the microwave for 5–10 minutes to allow the electronics to reset, then plug back in and test.
- Ensure the supply voltage is stable and within the range specified in the Teka manual.
- Verify that no other error codes appear and that the door closes properly.
Technician-level overview:
- Inspect the inverter PCB for burn marks, cracked solder joints, or swollen components.
- Check all harness connections between the main control board and inverter module.
- Measure input and output voltages according to Teka service documentation.
Recommendation: E05 generally requires replacement of the inverter module or main PCB and should be handled by an authorized service center.
