This is usually caused by either a bad door switch (usually the top one), 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.
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.

Sorry, but how was my solution inappropriate??
Looking at recent model LG microwave schematics, everything points to a failure of the top door switch or its mount...
I would again refer you to my answer above.
As shown in the sample drawing below, there are hidden switches that get activated by the hook-like projections on your microwave's door whenever the door is closed.
That's how the microwave knows whether its door is open or closed.
One of those hidden door switches (probably the top one) is not getting activated when the door is closed.
That's why it won't heat.
It's a little bit like the door switch on your clothes dryer - if you open the door, it stops running.
Or the door switch on your fridge that turns the inside light on when your open the door and turns it off when you close the door.
Sorry if I didn't make that clear.

To clarify, the plate is turning and the light is on but there is no heat on microwave, convection or any of the settings. Basically it is not cooking/heating up at all.
There is nothing wrong with the door. It is simply not cooking.
Can you clarify what you mean by "not cooking properly on any setting"?
Thanks.
My microwave convection oven just stopped working and the error code 0--o came up.
Error code f2 is displayed on screen once the cooking has completed
