Although your model number doesn't seem to show up, the NNS950-series units are powered by an high-voltage inverter. And yours has failed. 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. Sometimes a whole new inverter is 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 appliance / microwave repair shops and ask then specifically about inverter component-level repair and simple inverter replacement costs for your exact model number.

If the screen is showing a fault number or a number you havent seen before then its probably a program fault which can't be fixed. Check that the vent holes on the back of the oven aren't dirty and ensure that the whole oven is clean inside. Sadly it sounds like a program fault which cant usually be fixed by the owner though.
Finding a Panasonic oven repairer in the UK shouldnt be a problem though. My parents had a simlar problem wth their Panasonic Inverter oven, called the UK customer services and Panasonic contacted an authorised repairer in Scotland to visit them. Call customer services on 0844 844 3868.
If the call out charge exceeds £80 then you're probably better off buying a new oven.

This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.
The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.

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.

If
the digital programmer circuit / controller does not get a feedback
signal from the inverter for a period of 3 seconds, the controller will
stop the cook cycle.
Due to the lethal
voltages used and produced in inverters, I do not recommend that an
inexperienced person work on these.
