3 second cooking time
It's possible a sensor or thermistor got unplugged during your work and didn't get plugged back in.
Otherwise, I would suspect the microprocessor got "glitched".
If so, *maybe* unplugging the oven from the power line for a few minutes will reset it. Or maybe the unit has a reset button or another reset procedure (I doubt that, but check the manual).
Sadly, another common cause for this is that the code in the microprocessor gets irretrievably corrupted.
In such cases, we can replace micro if it is available. It it's no longer available, that would make the whole microwave a goner.
Looks like both the micro (LSI display) and the whole control board for this model are available from Panasonic parts: http://www.pasc.panasonic.com/epartr
