Microwave displays E-22 and may not start or may shut off quickly.

Critical Safety Warning: The inverter and magnetron operate at extremely high voltage and can be lethal even when unplugged. Do not attempt to service the inverter or magnetron unless you are trained and know how to safely discharge the high-voltage capacitor.

• Basic reset only: Unplug the microwave for 10–15 minutes, then plug back in and test. If E-22 returns, internal high-voltage service is required.
• Check external factors: Ensure proper ventilation and that the unit is not overloaded with extension cords or power strips.
• Professional service: E-22 typically indicates a failed inverter or magnetron. These parts require specialized tools and safety procedures to diagnose and replace.

For your safety, contact an authorized Kenmore service provider for E-22 faults.
