Inverter Technology

Panasonic Inverter Technology perfects the art of cooking with microwave ovens, delivering delicious flavor, excellent color, and superb shape and texture in the foods you cook. The consistent delivery of microwave energy means delicate foods can simmer without the edges and surfaces overcooking. Foods have the look and taste you expect without the wait!

Inverter Turbo Defrost Adds a Little Cooking Boost

Panasonic has succeeded in evolving Turbo Defrost, which allows you to defrost foods even faster than previous Panasonic Auto Defrost. Panasonic Inverter Turbo Defrost technology is an advanced microwave sequencing system using the Inverter low-power delivery feature.

Keep Food Warm Until You're Ready to Eat

A pulsing delivery of very low microwave power keeps the temperature of your food at a constant level without overcooking. Our improved keep-warm menu now includes five items, so food like stew, gravy and desserts can stay warm in the oven until you are ready to serve.

Reheating and Cooking Made Simple

One-Touch Genius Sensor Cook and Reheat adjusts power levels and calculates cooking times automatically, making reheating and cooking a variety of foods easier than ever.

Multi-Lingual Menu Action Screen with Function Key

The Menu Action Screen is like having a gourmet chef to assist you in the kitchen. It scrolls step-by-step cooking instructions across the display in a choice of English, Spanish, or French. Our Function Key simplifies the programming of 10 useful, non-cooking functions. Just press the Function Key and the Menu Action Screen will display easy-to-follow steps to complete the desired function.

Clean and Smudge-Free Cabinet Finish

The Stainless Fingerprint Resistant finish on the front of our Genius Prestige Microwave ovens helps reduce the amount of unsightly smudging normally found on stainless appliances. So your microwave will look its best even when you are preparing some of your messiest recipes.

Sleek Control Panel with Blue LED Display

The silver button control panel, illuminated neon blue spin dial and generous 6-digit expanded LED display provide a high-end look and an effortless navigation experience in the kitchen.

Make More Room on Your Countertop

The Prestige Countertop Microwave Oven can also be installed in the wall using an optional matching trim kit accessory.

Rated 3.3 out of 5 by 22 reviewers.
Rated 4 out of 5 Great oven, but magnetrons fail I have had this oven for 5 years, but I had it replaced once for the H98 code. After 2 more years, I got another H98 code. It could be the magnetron, but it's just easier to order a new one with ext wty. Overall, it's a fantastic product for reheating and clean appearance. September 9, 2015
Rated 5 out of 5 Had one before needed a new one this the one I wanted July 24, 2015
Rated 1 out of 5 by 2 failures Bought 1st one and it quit working after 18 months. Since I had purchased trim kit, bought another and it died after 3 months. Fortunately under warranty but have to ship it back as there are no factory dealers here. If it weren't for the expensive trim kit, I would switch to another brand! July 21, 2015
Rated 5 out of 5 by This is my second one. The first on got hit by lighting and my wife would not settle for any other. Must keep the cook happy. June 20, 2015
Rated 5 out of 5 by Good large microwave We've had it almost two years without problems. It is large, which we wanted, but it does take up more counter space. We dropped/broke the original microwave turntable glass tray and just ordered the replacement for a decent price from Panasonic. April 30, 2015
Rated 4 out of 5 by Beautiful unit This Genius Prestige Inverter replaces an identical model (made 6/12, installed 7/13) that died at 20 months -- but we knew from reading reviews there was a chance of that happening when we chose it. Panasonic tech support says the earlier units' known problems have been corrected, so we bought one again. For us, it is still the best product out there! We think this NN-SD997S microwave is excellent -- really beautiful (cabinet-installed, with SS trim kit), intuitive, and easy to use. It's powerful, very big inside, and it works great. The Inverter Turbo Defrost, in particular, is the best microwave defroster I've ever used -- thaws foods fully without cooking the outside. April 22, 2015
Rated 4 out of 5 by Good Microwave I bought this after trying several other brands that were either malfunctioning or quit after a few weeks. I chose Panasonic because I had had one a few years before that lasted and lasted. The microwave works as expected only faster. Thank you for offering a dependable product. March 24, 2015
Rated 1 out of 5 by Terribl I had the same problem many other users had. The door interlock failed in 20 months. It cooks and functions just fine, but the door interlock design is simply amateurish. DO NOT BUY THIS MODEL - or any other Panasonic model with the same type of interlock. November 16, 2014
