Hi Michael,
i think something wrong with its high-tension circuit or your magnitron is bad.
the minor fault is open of therm stat for protection.
or burnt fuse in circuit.

If
it stops after 22 seconds, that means the controller has detected a
problem, usually 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.

Does this unit have a turntable? If so does it turn when on?

Hello :
This happens because of a bad door switch . The plastic mounts inside
the microwave which hold the door switches and onto which the door
latches lock when you close the door .
Check also the turntable .
It could be out of it's right place .
WARNING :
1:Don't
slam your microwave door because this may cause the fuse to blow and
this is the reason of bad door switch problem .
2: A microwave is
capable of giving you a serious electrical shock even when it's
unplugged , so I recommend you to call a repair technician for help .
please
don't forget to rate .
good luck .

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts (including a fuse and the diodes), then most likely the magnetron is done and a new microwave is the way to go.
Let me know how this works out for you.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is
discharged!!!!! before attempting any sort of repair.
Check
the door interlock switches first then the high voltage diode with
either an AVO model 8 on high resistance range for short circuit, the
capacitor can fail and go short circuit, the feed fuse on the primary
of the high voltage transformer and then finally, the magnetron is
best checked by substitution.
Hope that helps.
