We had a Whirlpool prior to this and the microwave failed years ago, while the oven was still functioning--never get a combination unit for that reason.  Installed on 12/27/2012 and ever since then, there are three types of malfunctions in the microwave:
1.  There is still :01 secs in the timer left when the microwave reads "Cooking Complete" and beeps.  This seems to be the most innocuous, as otherwise the food gets hot.  May be a rounding error in the software, but happens very frequently.  I will upload a video.
2.  In this one, the microwave is on, turntable rotates, counter counts down, but the sound is a low hum of the turntable rotating, but the fan is not on.  This is with the regular microwave function, not the convection part.  So far, this has happened about 6-7 times.  We haven't tested the food, whether it gets hot during those times.  I haven't been able to replicate it, as when the technician came, but fortunately, I had videotaped it as it happened again the day before he came.  It happens at random times and random settings.
3.  This third type has happened about thrice so far, where when time is entered for a full power cook function and upon pressing start, nothing happens.  No sound, no countdown, no turntable rotating, but the microwave displays "Cooking..." as when it does when everything works correctly.  So far no luck with customer service.  Will report if anything changes.

Updated on 3/5/2013.  I have uploaded videos of the above malfunctions at: [...]

Updated on 07/25/2013.  I notice that there are more people having issues with this unit.  Please post your complaint on: [...].  That was the only way I got a prompt response and they eventually replaced the unit, as I had meticulously kept a video log of every event of malfunction.  That didn't solve the problems, but they happen less frequently in the new unit.  Best advice for people considering this unit is to stay away!

Updated on 11/14/13.  Our saga continues even with the replacement unit.  I wanted to wait and see, even ignoring the timer not counting down to zero before displaying "Cooking Complete" and the fan not turning on or off as it does sometimes.  On 11/11, when the microwave did not even turn on, even when the display said "Cooking", it was the last straw.  I have complained on their facebook page and will wait to see what action they are going to take.  If replacing the unit did not solve the problem, I don't know what will.  Obviously, there is a problem with this model.  Please stay away.  Do not buy this product.  If there was a zero star rating, I would give it.
