I have a 2004 Sharp R-1214 1100 Watt Microwave and the card like removable 3 x 4 inch plate broke (almost like cardboard) and it covered the vented opening. I don't have a users manual so I don't know the part description or number. Are they replaceable?

I'm going to try one more time. It seems this stupid site has some problems sometimes and cuts off links. I don't know why. I've put in parts links like this dozens of times.

This is upsetting. I see now it's cutting off everything I enter after the ampersand. What a stupid thing. The Sharp part number is PCOVPB085MRP0. You can find it at www.encompassparts.com or www.partstore.com. I use Encompass for most parts. This is upsetting. I see now it's cutting off everything I enter after the ampersand.
