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.
