Possible Causes
Failed magnetron, Open high-voltage diode, Defective high-voltage capacitor, Faulty door interlock preventing HV enable
How to Fix / Troubleshooting
Safety: High-voltage components are dangerous. Limit yourself to basic checks unless you are trained.
User checks:
- 1. Verify correct settings: Ensure you have selected a microwave power level (not just timer or clock) and that child lock is off.
- 2. Test with water: Place a large mug of water in the center and run for 2–3 minutes. If the water remains cold, there is no microwave output.
- 3. Listen for changes: Normally, you should hear a slight change in sound when the magnetron energizes. A very quiet operation may indicate no HV.
Technician actions:
- Test magnetron, HV diode, and capacitor for continuity and shorts.
- Verify door interlock switches are enabling the HV circuit.
Resolution: Replace the failed magnetron or HV components with IKEA-compatible parts.
