Possible Causes

Blown cavity lamp, Shorted lamp holder, Faulty lamp relay on control PCB, Wiring short to chassis

How to Fix / Troubleshooting

Safety: Unplug the microwave before replacing the lamp.

  • Access lamp: On many Amica models, the lamp is accessible from the rear or side via a small cover. Remove the cover screws.
  • Inspect lamp: Check if the filament is broken or the bulb is darkened. Replace with the correct wattage and type specified by Amica.
  • Check lamp holder: Inspect the lamp holder for heat damage or signs of arcing. Replace if cracked or burnt.
  • Test operation: Reassemble, plug in, and open/close the door to verify correct lamp behavior.
  • Further diagnosis: If E14 persists or the lamp stays on, the control board relay may be stuck and the main PCB may need replacement.
