It will come back on but it doesn't stay on like it did before it was repaired. How do I set it?
Replace the control board with a new one
SOURCE: Microwave runs for 3 seconds and shuts off
This is an inverter-driven model, and this is one way the inverter fails. Often it will tick, too, but the cooling fan may be too loud to hear ticking. If you haven't had smoke, then it may not yet catastrophic. I would bet that a thorough resoldering would take care of it. A good technician can troubleshoot and repair this, as needed, but often they will just replace the inverter. Sometimes that's actually cheaper. Troubleshooting an inverter is way too much for someone without good solid technical experience. I would call a shop and ask for an estimate to replace the inverter. Good luck.
SOURCE: Microwave cuts out after 23 secs
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:

Sadly, we hear of this over and over.
This
is due to a defective or loose magnetron causing electrical
interference and disruption in the control circuit board.
If
your magnetron was recently replaced, it may have loose mounting nuts
or bolts or maybe the wire mesh RF gasket was not installed or got
pinched.
It may also need a new high-voltage diode and stirrer, and the cavity may be affected.
Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.
(Your model may use a different kit - this is shown for illustration purposes only).
If
you or someone you know decide to look into it, we have critical
information on safety, disassembly and door switches at our site, and
our link is at our listing here on FixYa.
There
should also be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
If
it's within the magnetron portion of the warranty (usually 5-9 years)
but out of the original full warranty (usually 1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
They may even send you a replacement magnetron. GE Customer Service is here.
Good luck.

-SE- error means you have a shorted keypad.
If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

SOURCE: MICROWAVE WILL NOT HEAT. F9 APPEARS IN THE DISPLAY WINDOW
F9 indicates a problem with the door latch. There is a safety switch that will not allow the microwave to operate if it detects the door is not closed properly. Even though physically it may seem the door is shut, the safety switch is not relaying the message to the onboard computer. You need another door latch switch.
If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently
If
the microwave runs for a few seconds and stops there may be a short
circuit in the main control board. Check other components first,
these boards are often misdiagnosed.
If
the microwave runs for a few seconds and stops the touchpad and
control panel might be defective. There are several other components
that can cause this problem, be sure to check any other components
before replacing this board.
If
the microwave runs for a few seconds and stops the touchpad might be
at fault. This is not common. Generally speaking, if the microwave
display is working and some of the buttons respond correctly but
some don't, the problem is with the touchpad.
If
the microwave runs for a few seconds and stops the high voltage
transformer might have an intermittent short. This is not common.
Check other components related to the microwave symptom first.
If
the microwave runs for a few seconds and stops the thermostat might
be defective. Watch our video on testing thermostat
