Is the door fully closed?
Remove all packing material from the Microwave.
Be sure no packing material is blocking the door lock system.
Place the microwave oven on a flat and level counter, table, shelf, or cart, that will not block the opening or closing of the microwave oven door.
Close the door firmly.
NOTE: To avoid unintentional operation of the microwave oven, a cooking function cannot be started if the microwave oven door has been closed for about 5 minutes. The word “door” will appear in the display until the door is opened and closed.
