Possible Causes

Weakening magnetron, Failing high-voltage capacitor, Low mains voltage, Turntable not rotating properly

How to Fix / Troubleshooting

User-level checks:

  • Confirm that the turntable is rotating smoothly and not slipping. Re-seat the glass tray and roller ring.
  • Test the outlet with another high-power appliance to ensure normal voltage and no dimming lights.
  • Try heating a standard cup of water for 2 minutes; if only lukewarm, output is low.

If low output persists:

  • The magnetron or HV capacitor may be failing. These require high-voltage testing and replacement by a technician.
