Buy Panasonic microwave plates from Panasonic or Amazon.com. Panasonic has an online store with a microwave accessories page. The company sells plates for several models, roller rings and trim kits as well.
Panasonic microwave plates are compatible with specific microwave models. Panasonic doesn't specify which plates go with which microwaves on its website, so customers must know what codes apply to their machines before ordering. Amazon.com provides the option of emailing a customer service representative before placing an order for a Panasonic microwave plate so as to confirm which plate to purchase. This is helpful in cases where customers do not know which plate is compatible with their microwave.
