Easy....the reason the light does not go out when the door is closed and the microwave gun is not activating...is due to your door switch not "sensing" it being closed. Sometimes there two electrical switches on the door...yours probably have one and the actuating arm...metal tab on the switch is probably bent and need to be re-bent to sense door closure. Take apart the microwave and re-bent this switch tab...it's relatively easy to find and correct. The door switch might be bad too...won't cost much. 9 times out of 10 it's a bent switch bar.

Essentially you remove the vent grille held on by screws and/or clips then you'll see a screw at the top of the control panel.
Then the control panel should either lift up and out or forward and down.
The fuse is normally near the door switches, on the floor behind the controls, or on a metal plate near the transformer or fan.
There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

The actual model number is like JVM1460. XL1400 is just a "line" and won't help in finding parts.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

A microwave can be dead for many reasons.
If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.
You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.
If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If
it goes dead or blows the breaker or GFI when you plug it in or open or close
the door, then there's a problem with a door switch or door switch
mount.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door
switch or mount trouble can be 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. Other times, 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.

information on safety, disassembly and door switches at our site, and

Thanks for the photo of the label!
It shows the FCC ID number, which I used to find schematics at the FCC Web site.
The problem is a shorted primary interlock switch.
This is the door switch which has two black wires connected to one terminal and a black and a blue wire connected to the other
terminal.
