In most cases, this is a problem with the inverter or 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.

Everything else can work perfectly fine but if it doesn't generate microwaves to heat your food than it is not working ( you knew that anyway).. Unfortunately, and in most cases when you microwave stops working in that manner..the components at fault are either the Magnetron, Filament PS or a High Voltage Capacitor..What that means is that you are probably better off just replacing the entire appliance rather than attempting to repair it. If it is a year old or less, bring it back to where you purchased it and have them replace it.. I am sure that is not what you wanted to hear but when the cost to repair exceeds the cost to replace... it just isn't worth repairing.. Plus.. there is an element of danger associated with these kinds of repairs...

SOURCE: Everything works except heat
this is something you should probably call a repair technician for, due to the danger of the componentry.
Usually in ther case of this problem, even a technician will advise you to replace the unit, in the minds of cost effectiveness and safety...

SOURCE: Microwave doesn't heat anything
Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.
The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.
There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.If turntable is not running check also the door switch.
The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
Parts must be tested to find out what is wrong.
Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.
Regarding parts, contact the seller here to purchase parts.
You can also order from MicrowaveSvc , they also provide parts.
