If the microwave turned off completely after you opened the door and you have already tried other outlets and circuit breakers, it could indicate a malfunction in the microwave's door sensor or control panel. It is advisable to have a professional technician inspect and repair the microwave. If it's only 3 years old, it might still be covered under warranty, so it's worth checking with the manufacturer.
