the list of serial numbers below when this change came into effect:
R22AT from s/n 07093XXXX.
R23AM from s/n 07093XXXX.
R24AT from s/n 07093XXXX.
We have changed the parts available for the model manufactured in 1998 and 1999.
The rib and boss of the doorframe were deleted, and holes on the door panel were
deleted. As a result, the old door frame cannot be fit to the new door panel.
If necessary, delete (cut) six pieces of rib and boss off the doorframe, so that the old
doorframe can be fit into new panel. Refer the attached drawings, page 2 and 3.
This change does not have influence on the product performance like microwave
output power and microwave leakage, etc.
