Inverter Technology

Moving Beyond Just "Heating Things Up"

Many people just use their microwaves for making popcorn or warming up soup because most microwaves just have one temperature setting--high. Conventional microwave ovens might have a low-power setting, but this is achieved by "pulsing" the high-power setting on and off rather than by emitting a steady stream of low-powered energy.

Panasonic's trailblazing Inverter technology delivers true, variable microwave power, which means even temperatures and consistent textures throughout the food being cooked. The consistent delivery of microwave energy allows delicate foods to simmer without the edges and surfaces overcooking, so foods have the look and taste you expect--without the wait.

The Inverter microwave oven perfects the art of cooking, taking microwave cooking to a whole new level. You'll experience delicious food that better retains its color, nutrients, and flavor and that's easier and faster to prepare. Oh, and you can still make great popcorn.

Single, Compact Power Supply

Furthermore, the Inverter power unit is smaller and lighter than conventional microwave circuitry (aka the heavy, enclosed side of the microwave), which allows for more interior space to fit that favorite casserole dish, without increasing the oven's overall exterior dimensions. Weighing just 36-4/5 pounds, the oven's roomy interior measures 18-1/2 inches long by 18-7/16 inches wide by 10-15/16 inches high, while its compact exterior measures 19-7/16 inches long by 23-7/8 inches wide by 14 inches high.

Additional Features

One-Touch Genius Sensor Cook and Reheat

With the touch of Panasonic's Sensor Cooking button, the microwave takes the 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 automatically.

Inverter Turbo Defrost

Panasonic evolved the Turbo Defrost feature, 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 continuous-power delivery method.

Menu Action Screen (multi-lingual)

The Menu Action Screen is like having a 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.

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 for up to 30 minutes after cooking.


Time-of-day clock and versatile timer provide exceptional convenience.

Quick Minute

The one-touch button allows you to set or add cooking time in 1-minute increments up to 10 minutes.

Control Panel with Blue LED Dial Ring/Blue Backlit Display

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

Child-Safety Lock

For safety, the oven's child safety lock prevents electronic operation (door still opens). Press Start three times to lock ("Lock" will display); press Stop/Reset three times to cancel.

User-Friendly Control Panel
Push-button controls, illuminated dial, and backlit display for ease of use.

This is a terrific oven:

* Huge on the inside, very space-efficient on the outside. The turntable is 16.5" (42cm), and has 9.5" (24cm) vertical interior clearance. I was even able to mount this above our 24" built-in oven by modifying the trim kit.

* The "Inverter" technology really works. Everything cooks evenly without hot-spots. Consumer reports gives top marks for similar Panasonic ovens, and I can see why.

* The "Sensor" technology (measures steam) is usually reasonably accurate. So far we have not burned anything. Popcorn is perfect.

* The controls are intuitive, and the dial simplifies use.

* The front panel is uncluttered, and does not show fingerprints.


* Expensive

* You can't "add time" once the oven starts (though this would seem easy to implement with the dial). (see below for update)

* We have owned this for one month of heavy use, but some reviews indicate long-term reliability problems. (see below for update)


* The description is incorrect: the dial is fixed, and does not "pop-out" on this model. (description was later corrected)

UPDATE March 2010:

1) After >2 years of heavy use, this oven is still working great. Some of the text near the knob has worn off, but otherwise it looks just like new. At least for us, reliability has not been an issue, and we use it constantly.

2) The comment on this review is correct. You can add 1 minute while the oven is in operation with the "Add 1 minute" button. However, our previous oven allowed you to simply rotate the knob and add an arbitrary amount of time (say, 5 seconds). This was more intuitive and flexible.

We've had this microwave for several months now, after replacing an old one that was having trouble (which 1/4 of the plate that it decided to heat on any given day was apparently determined by the phases of the moon, or possibly sun spots).

First of all, this is a good size microwave. If you are upgrading from a smaller one, be sure to check the dimensions listed in the product description before ordering.

It's very well built. It gives the impression that it's probably going to last forever. All of the buttons, the dial, the door and its release mechanism are all very solid. The inner rotating tray and the rotation mechanism that it sits on are also well done -- even with a really lopsided load, the rotation of the tray remains smooth.

The performance of this microwave has been stellar. As mentioned in another review, the Popcorn mode is perfect -- I have yet to see a single burnt piece come out of a bag. The "Sensor Reheat" mode has been spectacular for me as well. Just put the food in, and press the button. I use it all the time for leftovers, and wow! As a matter of fact, just yesterday I used it to reheat a plate that included ground beef, mixed vegetables, and a large amount of mashed potatoes -- nothing was overdone, and the mashed potatoes were hot all the way through!

The unit itself is quiet -- it probably operates at about a third of the volume of my old one (admittedly, that's not saying much). My girlfriend thinks it's hilarious that the display says "Enjoy Your Meal" after it finishes heating.

There are a number of features that I haven't tried, since I haven't had a need for them yet. If I end up using one of these features in the future, I'll update this review with the new info.

NOTE: UPDATE -- I've had a chance to try many more of the features. They did not name this microwave GENIOUS for nothing! Bit by bit I have been trying more and more of the "automatic" functions. Bear in mind, I missed several generations of Microwaves because this one was replacing an approximately 20 year old model. This is the first microwave I have tried that could defrost frozen food without cooking it too. It cooks both rice and pasta very nicely (but I haven't yet hit the vessel/lid combination to keep it from boiling over a little). Overall this microwave has replaced electric woks, electric fry pans, quick cookers and other electrical devices I generally used in the summertime so I did not heat the kitchen up when cooking the evening meal. I recommended it to a friend and he too is in awe of it (same model, also purchased from Amazon). There are only 2 things I don't like. I miss repeated beeps telling me my food is ready. If I miss this one's announcement - well, too bad. The other thing is that it is difficult to monitor the food's cooking progress through the window which I assume is as it is to provide cooks from harmful micro-waves.
* * * * * * * * * *
This microwave almost seems "overbuilt", even though it weighs about 1/2 as much as my original Plastic woodgrain covered 600W Panasonic microwave from 1974 (that cost $600 new). I still have that old Panasonic, with a stainless steel cavity--which makes more sense to me than a painted cavity and a stainless steel exterior. I have relegated that old one to sterilizing starting soil for my greenhouse and other things garden related.

Until recently I was using two 700W GE microwaves (also old, 1988 and 1990) until one burned out. When I started to shop for a replacement I only considered Panasonic and GE models.
