Possible Causes
How to Fix / Troubleshooting
Safety warning: Magnetron and high-voltage circuit repairs are hazardous and should be performed only by qualified technicians.
User checks:
- 1. Confirm symptom: Place a cup of water in the oven and run for 1–2 minutes. If the water remains cold and E9 appears, the magnetron is likely not producing RF energy.
- 2. Listen and smell: Note any unusual humming, arcing sounds, or burning smells. Report these details to the technician.
- 3. Power reset: Unplug for 10 minutes, then retry. If E9 returns consistently, internal diagnosis is required.
Technician outline: Check magnetron connectors, test HV components, and verify the current-sense circuitry on the control PCB. Replace the magnetron or PCB as needed with Morphy Richards-approved parts.
