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 over 31 pounds, the oven's roomy interior measures 18-1/2 inches long by 16-7/16 inches wide by 9 inches high, while its compact exterior measures 19-7/16 inches long by 21-7/8 inches wide by 12 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.

I installed this microwave oven as a built in using a Panasonic TK-729SAPH Stainless Steel Trim Kit (27" width) for all 1.6 cuft Panasonic Stainless Steel Microwave models.

I purchased this oven because I like its looks, it can be installed as a built-in and its performance is rated very highly by Consumer Reports.

I am happy with the cooking performance of this oven. Items cooked in it are heated evenly. I have found the sensor cooking mode to work well.

Minor annoyances include that the door open button requires a pretty firm push to open the door and the control knob can't be used to select a power level. The control knob can be used to dial in the cooking time, or if you push the sensor cook button, the dial can then be used to select a sensor cooking mode. However, the power level is selected by repeated pushing of the power level button. If you want 50% power, you need to push the button five times. Obviously this isn't the end of the world, but it annoys me. I'd rather push the power level button and then dial in the power level I need using the control knob.

This oven looks great installed as a built in, it cooks well and I am happy with my choices. If I was going to do it all over again, I would still choose this oven and trim kit.

Bought it over one other, similar microwave, mainly to see if the inverter technology really works. It does. It's a great leap forward for humankind.

The knob is retro! Which in this case means solid. I did not buy it for the look, but it's funny when visitors think maybe it's a TV/microwave combo. It's solid like a 60s TV. And big.

This thing is big. I wanted big, so it's ok, but you might take out your tape measure to help conceptualize just how big it is. I am thrilled with how much I can cook or heat up in 1 batch--1 Correlle Winter Frost dinner plate plus 1 CWF bowl both fit on the turntable, and there's still room to stick some 1-4 oz. containers.

The stainless is nice. I have a mostly white kitchen, and white plastic on appliances turns yellowish over time, so I am glad there was a stainless option.

It gets the job done, whatever the job is. Buy it without fear.

Then double-check that Amazon is using the correct shipping address, and check again after your order goes through, and possibly once more before it ships. It's heavy and very bulky if you have to carry it home from work. If it isn't your mistake and you have to pay $30 to get it home anyway, it kinda puts a damper on the arrival of a fine appliance.


December 5, 2008 - January 8, 2013

It was used about 10 times per day, every day. No problems till yesterday; it arced and died.

Thanks to all the thousands of people whose reviews I've read over the years. HTH

With so many contradictory reviews on microwaves, my head was spinning from having to choose, and I finally went with this model. We've had it a few months now and overall I am extremely pleased.

5 stars: Cooking.
It cooks faster and more evenly that any microwave I've ever owned. LOVE this!

5 stars: Size.
Holds much wider dishes than a similar microwave of the same size.

5 stars: Stainless.
I've never noticed fingerprints on it. Looks great!

5 stars: Clock.
I don't know what problems this or similar microwaves had, but I have never had a problem seeing the
clock from any angle. It's bright blue and obvious. The knob is lit with a cool light blue ring.

4 stars: Ergonomics.
No problems opening it. My 7-year-old has had no problems. The buttons are a bit small if you're gonna
be picky about it. I lowered score down because the knob does increase in too large of increments after
the one minute mark.
Update after 1 1/2 years: I never notice any problems with ergonomics or button size when I use it.

4 stars: Power Levels.
Someone said they didn't like hitting the power to lower the power level, but it's a much simpler system
than I've had int eh past, and as rarely as you lower the power level, is not a big inconvenience. This
microwave can actually cook at lower levels, instead of just doing intermittent heating/not heating.

3 stars: Sensor reheat.
It can really overheat things sometimes. Usually I take them out at the first beep and
don't let it go on to a countdown cook. Better than just sitting there and testing the heat level.

2 stars: Quick minute.
I miss the "add 30 seconds" button on our last microwaves.

I owned a Panasonic microwave for the better half of 15-20 years and it worked wonderfully. Out of concern that a microwave lasting so long may not have the same radiation protection as it did when it was new, I upgraded to Panasonic's most expensive consumer model, the Genius Prestige Inverter Turbo. 3 months out of the gate and H-98 error appears. Panasonic sent me to the only authorized distributor within 2 hours of my house and it took over a week to have the new and special "Inverter Turbo" replaced (with a refurbished part, no doubt).

One year later, the microwave has H-98 again and customer support does nothing more than say it's been over a year since purchase, all costs must be burdened by me.

The abundance of web questions and reviews due to H98 errors is becoming ridiculous. Recall your product, FIX the problem, don't keep selling faulty merchandise!!

Microwave worked great for the time when it was...working. But spending $150-200 for a microwave that needs replacing yearly is entirely unacceptable. Will not buy another panasonic; that's for certain. Would not recommend it either. Not at all.
