Question about Panasonic NN-S951WF Microwave Oven
If you have a display and the inside light comes on when you open the door, it won't be the fuse.
First, please press and hold the Start pad for about 4 seconds to see if the child lock comes on. (This is detailed in the owner's manual).
If it does, that means the pad on the keypad is okay, and you can press and hold Stop to turn it off.
If it does not, then you may have a bad keypad.
I would suggest a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.
You are correct to suspect the door switches, especially if the Start pad is okay.
This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.
Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

Dead appliance, power on wall outlet.
SAFETY IS PARAMOUNT!
this only if you are competent.
your appliance has absolutely no functions at all, remove it from the
mains supply, remove the case and see where the mains lead goes in to
the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.
