Possible Causes

Failed inverter power module, Shorted magnetron drawing excessive current, Faulty current-sense circuit on control PCB, Loose high-current wiring connectors

How to Fix / Troubleshooting

Critical safety warning: Inverter-based microwaves contain high-frequency, high-voltage circuits that are extremely dangerous. Only trained technicians should service the inverter or magnetron.

User-level checks:

  • 1. Power reset: Unplug the microwave for 10 minutes, then plug back in and test. If E8 returns immediately, internal power electronics are likely faulty.
  • 2. Listen for abnormal sounds: A rapid clicking or harsh buzzing just before E8 appears suggests inverter or magnetron issues.
  • 3. Visual inspection (no touching): With the cover removed by a qualified person, inspect for burnt components or connectors on the inverter board and around the magnetron.

Recommendation: Due to the complexity and danger of inverter circuits, E8 faults should be handled by an authorized Logik service center. Component-level repair is not recommended for general users.
