Panasonic NN-C980 Convection/Microwave Oven Questions & Answers
I have a panasonic convection/microwave. Last
Since the unit makes the noise on Microwave but not convection it is a problem it he Microwave Circuit. Probably in either the rectifier of bad mag, one of them shorted. Just looked at the date you posted this, Im sure you have fixed or replaced this by now

Panasonic Microwave NN-C980-B buzzing noise but it still works.
All:
I have a 2003 Sears Ultra Wave microwave
721.63682300 with a similar problem. A few months ago it started giving off short buzzes when turned on. That stopped but then I noticed that everything took twice as long to heat up. After quite a bit of teardown&inspection I found a circuit break in the inverter board leading to ZD704 diode (pictured). I will now try to find a replacement diode to see if replacing will fix it. Thanks for your postings.

Panasonic dimension 4 microwave/convection oven
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.

When started,light& turntable operate
Check the door safety intertlock micro switch for proper behavior. If it is faulty, the oven will think the door is open and will not turn on the magnatron.
