Microwave error message that says it may need service, keypad shorted.
Microwave keypad sometimes doesn't work, sometimes it does, and sometimes it beeps or comes on by itself. I've watched a few fix it yourself videos and was wondering if it would be safe to open it up and just check to see if anything in the keypad control panel is loose.

SE is an error code for a shorted keypad, although the keypad might not really be shorted.
Unplug the oven for a few minutes to see if it clears the error code. If not, then leave it unplugged over night. If the problem persists, then you probably do have a shorted membrane switch on the keypad.
see the next steps. God bless you 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.

This sounds like a keypad problem, sometimes a short developes in the keypad controller causing all kinds of intermittent problems, on the back is the microprocessor circuit board which controls vital areas of the microwave oven. The cost to repair will be high and consideration should given to looking at a replacement.
the membrane gets dirt under them and shorts out the keypad,you may as well just replace the control board which includes the display and keypad on the same board
F1 usually means a shorted keypad or a problem with the control circuit board.
A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated.
Moisture and contamination can be caused by not using the fan when boiling on the stove top (for over the range models), direct spraying of cleaners, by storing the microwave in an unheated garage or shed, or infestation.
I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller.
Apply an alcohol-based cleaner (such as the purple kind) to a cloth (since paper towels can scratch) and gently wipe it off.
I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics.
You may have to contact LG support to see what that error code is and to find a local servicer:
