Possible Causes

Aging magnetron with reduced emission,Low mains voltage,Door leakage causing power loss,Partially failing high-voltage components

How to Fix / Troubleshooting

Safety first: Unplug the microwave before internal inspection.

User-level checks:

  • 1. Compare heating times: Heat 1 liter of water for 5 minutes on full power. If temperature rise is significantly less than expected, output is low.
  • 2. Check power setting: Ensure the power level is set to 100% and not a lower setting.
  • 3. Verify mains voltage: Avoid long extension cords and overloaded circuits that can reduce voltage.

Technician-level checks:

  • Test the magnetron current draw and high-voltage circuit performance.
  • Inspect door seals and cavity for leakage issues.
  • Replace the magnetron or other HV components as needed.
