Possible Causes
Shorted high-voltage capacitor or diode, Failing magnetron drawing excessive current, Loose power cord connection, Weak internal line fuse, Control board power supply fault
How to Fix / Troubleshooting
Safety first: Unplug the microwave. High-voltage components are dangerous.
- Check outlet and cord: Ensure the plug fits tightly in the outlet and the cord is not damaged.
- Observe behavior: If the entire unit loses power and the clock resets, suspect a fuse or power interruption.
- Inspect fuse: Remove the outer cabinet and check the line fuse. If blown, do not simply replace it without identifying the cause.
- Professional diagnosis: Because this symptom often indicates a shorted magnetron, HV capacitor, or HV diode, have a technician test and replace the faulty component and fuse.
