Inverter Technology

Panasonic Inverter Technology perfects the art of cooking with microwave ovens, delivering delicious flavor, excellent color, 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!

Genius Microwave

With the touch of our Sensor Cooking button, this microwave takes guesswork out of creating a great meal by automatically setting power levels and adjusting cooking or defrosting time. The sensor measures the amount of steam produced during cooking and signals the microprocessor to calculate the remaining cooking time at the appropriate power level.

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 Genius Sensor Cook and Reheat

The Genius 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.

Quick Minute Feature

The one-touch button allows you to automatically set the time in increments of 1 minute.

Rated 2.8 out of 5 by 4 reviewers.
Rated 2 out of 5 by Door latch mechanism The door latch mechanism is a piece of garbage. Mechanism is all plastic and will fail within 3 to 4 years. Very bad design. I have replaced one of the switches twice in the last year. Probably because you must slam the door to get the mechanism to work properly now. Did love the microwave until the latch mechanism started to fail. May 23, 2016
Rated 2 out of 5 by Good oven ruined by faulty door latch Had my first MC with a handle for twenty-seven years. Couldn't replace similar size and power with anything but the push button door latch so gave it a try. After about a year and a half the door latch wouldn't "catch" anymore so hubby fixed it. That lasted a couple more years, now it won't close well enough to even turn the light off. The plastic parts in the assembly are too worn to fix. This all occurred just in time for Thanksgiving so we haven't checked with our appliance repair shop to see if a new latch assembly is even possible. In the meantime I found another similar #different brand# with a handle. Guess we'll see how long that holds up. This unit is four years old and in a two person adult household. Usage is moderate, and we don't abuse stuff. I am disappointed that I can't use it because I was very happy with every thing else. Please find better materials to close the door with. Paying a little more initially costs less in the long run. Thanks. December 8, 2015
Rated 2 out of 5 by Disappointed in life of microwave Bought a new one of this model about 4-5 years ago...thought it would last much just stopped working overnight; no warning signs...never even used the convection feature... July 9, 2015
Rated 5 out of 5 by refurbished microwave The oven was very well packaged and arrived in great condition. It has been a very good machine. I would definitely recommend buying from this source again. June 19, 2015
