Remove, discharge, and test the capacitor to determine if it requires

- Thermal CutoffsExamine
the thermal cutoffs on both the magnetron and the oven itself. Take off

There can be short in the ribbon connector that connects the control panel to the rest due to some oily deposits. You can try to open it up, remove the ribbon, clean it and put back. It may take a few attempts to align correctly.
I am assuming your model is similar to mine.

Control panel not working
If you can open up, try to clean the ribbon connector.
My oven was sending "1" all the time, filled the memory and caused permanent beeping! I wanted to cut off the "1" connection but after opening I found that the panel was diffuclt to disassemble. I just cleaned the ribbon connector and put it pack. It needed a few attempts to get it to work all the buttons properly. But then it has been working for more than year without problem!

a stuck key or non-responsive key, most of the time you will have to
replace the keypad for this microwave oven repair. If your keypad is
connected to your control board by a flat ribbon wire, try disconnecting
it and clean the silver contacts with an ordinary pencil eraser. After
cleaning, plug it back in and try it. If it doesn't fix it, replace
the keypad unit. Some units actually have keypad tests to confirm your
diagnosis of a bad key.If your keypad and control is the same
unit, replace that unit. Another note, unlike stove/oven keypads and
controls, most microwaves do not have error codes or tests to
distinguish whether it is truely the keypad or control. Most of the
time, it is the keypad that needs replacing, but a small percentage of
the time it can be the control. Check the tech sheet if they can point
you to the right part.

Microwave control sparked
There is a major short in the keypad control board, this may be a good time to consider a new microwave oven. The parts and service call will easily cost more than a new one.
