    6. Place door assembly on a soft cloth with latches facing
    up.
    Note: As the engaging part of choke cover and door frame
    are provided at 15 places, do not force any particular
    part.
    CHOKE COVER
    7. Insert a putty knife (thickness of about 0.5mm) into the
    gap A between the choke cover and door stopper and
    between the choke cover and the door frame as shown
    Figure C-3 to free engaging parts.
    8. Pry the principles of the lever and  lift up the choke cover
    by inserting a putty knife in order shown in Figure C-3.
    9. Now choke cover is free from door panel and door frame.
    DOOR FRAME
    10.Remove six (6) screws holding the door panel and the
    door handle to the door frame assembly.
    11.Release the door frame assembly from the door panel.
    NOTE: It is easier to release the engaging parts of the upper
    or lower door hinge pin side at first.
    12.Now, door frame assembly is free.of microwave energy from oven cavity during
    cook cycle. This function does not require that
    door be air-tight, moisture (condensation)-tight
    or light-tight. Therefore, occasional appearance
    of moisture, light or sensing of gentle warm air
    movement around oven door is not abnormal
    and do not of themselves indicate a leakage of
    microwave energy from oven cavity.
