    I Have a NN-S573 Panasonic Inverter model and it cuts out at exactly 23seconds. It sounds like the same issue.

Panasonic microwave convection oven model NN-CD997S works normal but stop heating

Judging from the model and without looking it up I expect that unit has an inverter. If it is not the Switches and you have replaced the mag, the inverter is the power supply for the mag to work so either mag not getting power from inverter or inverter not getting signals from main PCB Timer board.

Can you replace the waveguide in a model NN-SN756B Panasonic microwave oven?

Generally, there are no user serviceable parts in a microwave oven due to the dangers of exposing yourself to microwave radiation. There are special screws that can only be removed by technicians who have the right tool.

However, I did find this.

How do I get my Panasonic Inverter microwave out of demo mode? I think my toddler might have hit something to put it in demo!

Hello Two options to try: a) Press the Clock / Timer button 3 times b) Unplug, wait a few seconds, then re-plug to power up with the factory settings. You will need to reset your clock and any favourite settings.
This should work with all Panasonic Microwave models.
Good luck

Micro Wave shuts down

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.

NN-T990SA Panasonic Microwave Stopped Heating

This model uses an inverter to produce high voltage instead of a convential transformer system. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Some manufacturers do not encourage or assist technicians to repair microwave inverters. Most offer the inverter as a whole assembly. But sometimes that is actually cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized repair shops and ask then specifically about inverter repair and inverter replacement costs for your model number.
