How to Fix / Troubleshooting
Safety Warning: Unplug the microwave before internal inspection.
User checks:
- 1. Dedicated circuit: Ensure the microwave is on a dedicated 15–20A circuit and not sharing with high-draw appliances.
- 2. Avoid extension cords: Plug directly into a properly grounded outlet.
If F7 continues, a technician should inspect the line filter, transformer, and motor circuits for shorts or overload conditions and replace any defective components.
