Microwave Ovens Master
Re: How to change the bulb on a Panasonic Microwave NN...
You are probably right.
Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.
You now must generally remove the outer cover to replace the bulb.
In many over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job and it's really helpful if you have your original installation instructions to do this.
Many models use one halogen lamp to illuminate the cooktop and another to illuminate the cavity. You must not touch them with your bare skin as the oils will shorten the bulb life.

just disconnect from the power and take out the screws from the cover around and you will see a plastic color white then remove a screw from them and you find the bulb replace and return all parts back
Hello, I also have a Panasonic Microwave ( model NN-S 564 or 574 ?) They are very similar.
I have just removed the outer cover 5 screws ( unplug of course ) and have located the bulb holder which is a white plastic component with two clips holding the globe, pull it out and remove the two spade clips connected to the globe. The globe will come away attached to a black plastic mount. Next........do the run around to find someone who sells it.
Perth has an authorized distributer/repairer in Myaree whose details I got from Panasonic. He may sell them. otherwise I will try a couple of specialist light globe suppliers I know....PROLAMPS in Belmont and one in BALCATTA whose name escapes me but I have been there before...Hope this helps others.
If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms.
The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating.
As long as you have good air flow through the vents, it sounds okay.
The fuse will be a white or gray ceramic fuse, and you really can't tell if it's blown without actually measuring it.
If a new fuse blows when you hit START, you probably have a shorted high voltage capacitor.
If you have replaced the fuse and still have no display, then it sounds like there's a problem on the control board.
The control board has a built-in surge protector which can short (and smoke) and when it does, it will cut the power to the control board, but not blow the fuse.
We repair these nationwide for only $39.95 postpaid.
