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.
