How to Fix / Troubleshooting
Critical safety warning: The magnetron and high-voltage circuit are hazardous. Only qualified technicians should perform high-voltage tests.
- Basic checks: Unplug the microwave and inspect for obvious signs of overheating or burning around the magnetron and high-voltage area.
- Ventilation: Ensure vents are clear and the cooling fan operates properly. Overheating can affect magnetron current.
- Professional diagnosis: If E5 persists, the magnetron or inverter/transformer likely needs to be tested and replaced by an authorized Fisher & Paykel service technician.
