This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
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.

SOURCE: LG microwave no longer heats!
It sounds as though you may have run the microwave while empty, which can damage the magnetron.
Not that I'm optimistic, but the first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.
Let us know if the hard reset doesn't fix it.
Otherwise it likely needs a new magnetron.
SOURCE: Microwave turns on, but no heat or turntable movement
The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck
SOURCE: Microwave won't heat, and turntable doesn't turn
All the parts you mention are very inexpensive, but yours does not have a triac.
It could be the cook relay, but it's more likely to be a switch.
Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.
Even though a door
switch clicks, it may still be bad inside.
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.
If you have a broken mount, it's usually more economical and
safer to just add a dab or two of hot glue to the mount to secure the
switch. Let it cool for about 30 minutes before using.

There may also be a "mini-manual" hidden inside the unit behind the control
panel or elsewhere, which is very
helpful when troubleshooting & testing.

our Web site, we have a video

over the range control panel assembly in under 5 minutes.
If you only need a
switch, you can order a universal type here for $5 postpaid.

Microwaves are a quick, convenient
solution to the hassle of preparing and cooking hot dinners. They are
popular appliances with students and large families where food often
needs to be prepared fast. Microwaves use radio wave technology
harnessed through an antenna, known as a "magnetron," to create friction
between food or liquid molecules, causing them to heat up. Some
microwaves can cease to function properly, resulting in the appliance
running but failing to produce any heat.
