Turntable turns when plug in. Cannot stop it with button or open door

I bought a Panasonic microwave NN-SU656 in 2017 and it works fine until this week. It triggered a circuit breaker and after that the turntable turns when we plugged in. No matter we hit "Stop/Reset" or open the door, it just keep turning. I would like to know what is suspected failure parts that can cause this issue and if I can fix it by myself. Thank you!
