You can download your owner's manual here.

If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

The screws you need to remove should be pretty obvious, and a special driver (such as a T20H Torx 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.

Panasonic microwave convection oven model NN-CD997S works normal but stop heating

Judging from the model and without looking it up I expect that unit has an inverter. If it is not the Switches and you have replaced the mag, the inverter is the power supply for the mag to work so either mag not getting power from inverter or inverter not getting signals from main PCB Timer board.

Replacement light bulb for Panasonic NN-9853 Microwave

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. 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.
