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.
