Question about Panasonic NN-S550WF Microwave Oven
Microwave cuts out after 23 seconds on any program and goes back to clock display. Can re-set to run for an other 1 minute, but cuts out again at about 23 seconds and returns back to clock display.
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:

The magnetron may have either failed or
is not being supplied with the extremely high voltage required to run
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 feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
