Important Safety Notes
Warning: Many microwave oven errors involve high-voltage components that can store dangerous electrical charges even when unplugged. Never attempt to repair internal components yourself unless you are a qualified technician. Microwaves contain capacitors that can deliver fatal shocks.
When to Call a Professional:
- Any error involving the magnetron, high-voltage transformer, or capacitor
- Persistent errors after basic troubleshooting
- Burning smells or sparking inside the unit
- Physical damage to internal components
- Multiple error codes appearing simultaneously
Basic Troubleshooting Steps:
- Unplug the microwave and wait 5-10 minutes
- Check power supply and circuit breaker
- Inspect door alignment and cleanliness
- Clean ventilation areas and filters
- Plug back in and test
Contact Information for Professional Service: If error codes persist after basic troubleshooting, contact a qualified appliance repair service specializing in microwave ovens. Always provide the exact error code, brand, and model number when calling for service.
