Humming sound



○ Cause          

     Humming sound heard coming from the microwave oven.


○ Troubleshooting

     Humming noise can either be coming from the fan running or the Magnetron operating. The

    Magnetron will hum when in operation. Depending on the power level set, the Magnetron may

    not stay “on” the entire time. This is considered a normal operating sound.
