Inverter Technology

Unlike other microwave ovens, 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. Other microwaves mimic lower heat settings by turning the power on and off repeatedly, which can result in overcooked edges and cool spots in the middle. With Inverter, you can poach, braise and even steam more delicate foods, all with the speed and convenience of a microwave!

Inverter Turbo Defrost

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

One-Touch Sensor Cook and Reheat

The Sensor adjusts power levels and calculates cooking and reheating times automatically for various food types.

Keep Warm Feature

A pulsing delivery of very low microwave power keeps food temperatures at a constant level -- without overcooking. So, foods like stew, gravy, and desserts remain warm in the oven until ready to serve.

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.

Elegant Design with Push-Button Door Release and Stainless Steel Front

Elegant, attractive and easy-to-open, the microwave will look its best even when preparing some of the messiest recipes.

Rated 4.6 out of 5 by 5 reviewers.
Rated 4 out of 5 by great microwave So far its working great.Love that the light only come on when its in use, and not when ever the doors opens. October 11, 2015
Rated 5 out of 5 by sensor reheat works great This item is brand new to me in August 2015, but I love the sensor reheat. It works perfectly with reheating a platter. I was afraid it would dry out the thin cutlet of meat while also heating the pasta on the platter, but it was heated perfectly. I have not used all of the features yet, but intend to as this feature worked so well. Previous microwave was really just a guess at timing to reheat items. Hoping this lasts as long as my last microwave. August 12, 2015
Rated 5 out of 5 by Great microwave, simple to use. Highly recomend it for all. August 3, 2015
Rated 5 out of 5 Just what I was looking for. Works great! The technology is definitely a nice change. June 2, 2015
Rated 4 out of 5 The right sized unit for the job This mircowave replaced one in my office kitchenette and it's the perfect size as it sits on top of the refrigerator. It's used by 10 people as some use it 2-3 times per day to warm food and drinks. It was a great price based on the type of replacement I was looking for as I found many others that were much larger (with more features I wouldn't use) and more expensive. April 7, 2015
