A:AnswerHello Teddy! The NN-SD987SA microwave oven can be used only with the following trim kits: NN-TK922SS and NN-TK932SS, as these are the only ones compatible. -G
A:AnswerI believe your problem will be that the 30 inch trim kits are not available and no one knows when/if they will become available. I had to make my opening like a “shelf” leaving sufficient room for venting per the Panasonic instructions. The microwave works well, is convenient, and all required dimensions for “built in” installation can be found on line.
A:AnswerHi! It means that it has been designed with Inverter technology. Inverter Technology delivers a seamless stream of cooking power –– even at lower settings –– for precision cooking that preserves the flavor and texture of your favorite foods. -M
A:AnswerSorry, it was a Christmas gift for our daughters fsmily. She liked this one that she had before this one went out, so it must have been a good microwave. It's not light, so I would recommend another person help you.
