How to Fix / Troubleshooting

Safety: Unplug the microwave before cleaning or inspecting rusted areas.

  • Clean and dry: Remove loose paint chips and clean the cavity with a mild detergent. Dry thoroughly.
  • Assess severity: Small, non-rusted chips can sometimes be touched up with microwave-safe cavity paint. Significant rust or large areas of missing coating can lead to arcing.
  • Do not use if arcing: If you see sparks or arcing from rusted areas, stop using the microwave.
  • Repair or replace: For serious cavity damage, professional repair or replacement of the microwave is recommended.
