Mine burned out within a month. Probably due to the poor design of the machine which forces you to slam the door to get it to shut.
My biggest concern is the under counter lightbulbs it has burned out in my kitchen over the last year. I wonder how much leaking this thing really gives off. Moving in a few weeks and will be throwing this cancer machine out.

Hi all, I have just replaced the bulb in my Panasonic NNA873 Dimension 4. Please be careful,although it was an easy job, there is a capacitor inside which stores heavy loads of power and will release the electricity into you if you touch it! YOU CANNOT REPLACE THE BULB FROM INSIDE THE MICROWAVE....... DO NOT REMOVE THE CARDBOARD-STYLE COVERING WHICH IS ATTACHED WITH ONE SCREW INSIDE THE MICROWAVE ON THE RIGHT. To replace bulb will take 5 minutes. UNPLUG microwave. Remove the outer cover by unscrewing about 6 screws (ordinary phillips) don't lose them into the workings....... Bulb is located on the right side, nearer to the front. You cannot see the glass of the bulb, only the black plastic end piece, as the bulb sits upside down and vertically. Best if you check out what a T170 looks like on the internet, then you will know what you are looking for. For my Panasonic I needed a T170 (but be careful, they have different ends, some are straight, some right angled - mine was right angled - check before you buy and no, I don't think you can get them from any ordinary supermarket etc!!). Do not touch the bulb when replacing as the oil on your fingers will shorten its life. Old bulb can be removed by taking out one screw and then pulling off the connectors - there is a little tab to push down to ease them off. Then simply replace bulb! When putting cover back on make sure all the tabs on top and sides go inside not outside casing. Good luck. This is an easy job, just don't poke around anywhere else.

That does sound odd! On one hand, I would suspect that maybe the door is getting slammed and that vibration may be contributing to the failure. But that would be much more likely for an incandescent bulb than a fluorescent type. Which is yours? You may have a bad connection on the socket which is causing some excess heat. Does the blown bulb look funny on the ends or at the connection? Assuming you're using the bulb your manual calls for, and the socket is okay, it may be a problem on the control board. Once you've digested this reply, let me know what you find and we can take it from there.

We see (and repair) this a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid.
This light failure often occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

SOURCE: Replacing bulb for microwave
If
there's no obvious removable cover over the bulb (most often on the
rear or side) and the owner's
manual doesn't address it, then disassembly will be required.
Always unplug a
microwave before removing or installing any bulbs.
If
it's an over the range type, remove the vent grille across the top and
see if bulbs can be accessed there. There may be a panel on the bottom
covering the light(s), instead.
If not, chances are
you'll have to remove it from the wall, then remove the outer cover. If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
You should be able to download your owner's manual from Panasonic.net by choosing your region & country, then Support.
Once it's out of the
wall, the outer cover (wrapper) will need to be removed, just as you'll
need to do on a counter top model.
On a
counter top model,
be sure it's unplugged, but otherwise ignore the instructions
above this paragraph.
You should be able to download your owner's manual from Panasonic.net by choosing your region & country, then Support.
The
screws you need to remove should be pretty obvious, but a special
driver (such as a T20H type or GTXH20-100) may be needed.
Be sure to put all the
screws back in the right holes, since some may be special grounding
screws.
Bulbs can be had in most
grocery stores, hardware stores, home improvement centers, and big box
or department stores.
Many models use halogen
lamps. You must not touch the new one with your bare skin, as the oils
will shorten the bulb life.
