The oven is 16 years old and works great except for the smell.

In most cases, this is a problem with the inverter but it may be a bad magnetron.
Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.
I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

High voltage parts: Capacitor, Diode, Magnatron are suspect. Need
to put a voltmeter on the input (primary) side to the high-voltage
transformer (big heavy iron thing in there) Should be getting 120Vac
when it goes to cook cycle. Don't touch the other (high voltage)
side of this transformer. If the power is there, you are looking
at replacing either the magnatron or the high-voltage capacitor and
diode. Its affordable if you do it yourself - buy the part on
EBAY - lookup "universal magnatron"
Hope ya fix it!

Fisrt, check to be sure your missing cat it not inside the unit. IF the interior is dirty (splatters, grease, etc.) , it may inhibit the unit from working properly.

Replace the door switch I ordered mine at www.repairclinic.com

It's almost certainly a shorted high voltage rectifier diode or a failed magnetron.
We have
the service / repair manual for this model and have uploaded
it to our
site here for free download to help you.
It will
give you safety info, step by step help in disassembly, troubleshooting
tips, and part numbers.
Here are some handy links you
or someone you know can use for test help:

(if it's not shorted or burned, it's
probably okay)

At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating
components.
You can also find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven here.
If
it's within the magnetron portion of the warranty (for this model it's 10 years from the date on the tag inside the unit)
but out of the original full warranty (1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
G.E. they will
send you the magnetron to do it yourself. Call them at 888-239-6832.
Be persistent. You may have to speak with a supervisor.
If it is not within the
magnetron warranty, you can find helpful
exploded view diagrams and order parts by entering your full model
number here.
Accessing some
components
(especially the oven cavity thermostat) for testing and possible
replacement will require you to remove the oven from the wall and take
off 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.

owner's manuals and installation instructions here.

The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven. A regular meter with a diode checker will not work to check these diodes. You have to use a meter with a 9 volt battery or put a 9 volt battery in series with the diode to check it.

If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.

If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testing.

If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food. When a high voltage transformer fails it will usually arch and have a burning smell.

If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

If the microwave doesn't heat the main control board may be defective. This is not common. When a microwave doesn't heat the problem is usually a faulty door switch or within the high voltage circuit; either the high voltage capacitor, diode, transformer or magn
