With the touch of the Genius Sensor cooking button, this microwave takes the guesswork out of creating a great meal by automatically setting power levels and adjusting cooking or defrosting time for added time-saving convenience.

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. A selection of 14 auto cook options enable you to quickly prepare your favorite foods, such as pizza, popcorn, pasta, soup, oatmeal and other dishes.

This Panasonic microwave oven externally measures 12-1/4-inch x 20-11/16-inch x 15-13/16-inch (H x W x D).

  1. Tech Savvy / Repair Savvy

    I admit I can sound like Abraham Simpson from time to time, ranting about the good old days when appliances lasted practically forever and were repairable when they weren’t, but this time it’s justtified. I grudgingly began the online shopping process for a new microwave after the 10 year old unit (a hand me down from my grandparents that replaced my prior 15 year old unit) finally quit, and as is often the case, nearly every unit whose reviews I checked (not just this brand, but also Sharp and others) all reported a high number of D.O.A. units or premature failures. Well, with trepidation I ordered this touchpad unit which arrived promptly and well packed, and I was initially thrilled with its special features like sensor reheat, as I cautiously placed it into service. Something told me I should “save the box”. Sure enough, after four delightful uses, most with sensor reheat, and certainly less then ten minutes cook time, the unit failed utterly with an “H98” error code (bad Magnetron/Inverter circuit), and won’t recover. So after just a few days, it is back in the (original, saved) shipping box, and lugging it to UPS for a return. Dagnabbit they just don’t make ’em like they used to.

    Here is the chronology of my experience with three different models of panasonic microwaves, including this model.I had a circa 2007 version of today’s panasonic NN-SN966S-1.6cu (sorry, I don’t remember if the model number was the same in 2007) which ran absolutely fine till October, 2014. I had to recycle it since it rusted from inside, otherwise no technical issues. I was pretty happy with that product and so went for panasonic again.In October 2014, I got a NN-SA661S-1.2cu from WalMart at $110. This one failed in August 2015 with error code H98 (i.e failure in Magnetron circuit). Luckily, it was under the 1-year limited warranty so the Magnetron was replaced by panasonic service center with free labor & parts. In July 2017, it failed again with error code H98. Since it is no longer under warranty, so I dumped it this time.Next, I wanted to buy a better one which would last longer, and I landed up in NN-SN686S. It looked a bit premium than the earlier model, so I wanted to give a shot at panasonic again. We got this one from amazon at $141 in August 2017. After 14 months, it failed last week (20th October 2018) with error code H98. Our usage is pretty light (not used for cooking but only for warming foods) and we maintained it well, so didn’t expect it to fail so soon. I called up Panasonic customer care to check if they would cover the repair, because Magnetron is under 5 year warranty (but labor is limited to 1 year). The automated voice assistant said that it will charge $10 for any out-of-warranty products. I was fine with that too, but panasonic customer care never landed me to a human. I tried with panasonic support live chat, which does not work at all. Basically don’t expect any customer support from panasonic. So, I called up the panasonic service center which is now located 20 miles away. They said Magnetron is covered but labor will be $65 and they accept carry-in for repairs only Mon-Wed. I haven’t decided yet if I would take this route….Neverthless, it seems none of the recent panasonic models run longer than 12-15 months. There is definitely a durability issue of the magnetrons. So, if you want to buy a panasonic microwave, consider it as 1 year investment (i.e the warranty period of panasonic).Here is an update. The panasonic service center charged $25 to diagnose the issue. The inverter is burnt out completely. The inverter is not covered by warranty and the price to replace it is additional is $162. The total cost $162 + $25 = 187 is more than the price of the microwave. The inverted burnt out which is not covered by warranty. So I dumped it. Will never buy Panasonic in my lifetime.

    I bought this recently to replace an old Sharp microwave that we had for over a decade. It is larger inside, yet overall smaller outside which is better for our limited counter space in our small apt kitchen. The extra power takes some getting used to, but once you realize how much better and faster and more evenly this microwave cooks and defrosts, you’ll adjust nicely to its use. It has many presets that are very useful for a large variety of foods which takes the guesswork out of figuring out how much time to set, as it uses a humidity sensor to detect when the food is done. I have had no issues with seeing the keypad, as others have stated, and the sheen of the exterior i find to be beautiful and easy to maintain, with a quick wipe down. We are very happy with our purchase, as Panasonic has always been a trustworthy manufacturer that makes reliable and rugged products, and this microwave is no exception.
