Sounds like the motor has blown, I did have this once before and I found by taking the glass plate out and turning motor top where plate rests on by hand a few times it started to work again but it might be gone anyway, you might be able to get a second hand one but a new one is about 30 pounds so might be advisable to renew machine.
I just repaired a different brand of microwave a few weeks ago with the same problem and all it ended up being was some loose screws on the bottom hinge. Take your plate out and then turn your microwave on it's back and see it there are screws in the hinge area and make sure they are tight. If they are, then it might be the upper hinge that is loose and you would have to take off the outside cover to reach those screws and more than likely you would need a special torx screwdriver to get those screws out. If you have access to that kind of screwdriver, just be careful when you take the cover off and put it back on that you get all of the clips back in the right place so that the cover goes back on correctly. Always remember to unplug your microwave if you are going to take the cover off.

You will need the free
Acrobat Reader
to view or print it in case you don't have it. If
you gently push up on the door latch heads (hook-like devices sticking out of the door)
there should be spring tension. If they just flop right up, the spring
is off inside.
Normally the problem is
not the spring, but a broken
spring mounting tab on the door latch head (hook) assembly or the inner
door panel.
If it's the door panel,
it's usually easier and cheaper to use epoxy and some kind of hardware
to fashion a new spring mount.
The door latch head
(hook) is easy to replace or repair if that's the issue.
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.
Or you can watch a YouTube video (not a video I made) here that
demonstrates how it's done.

If you remove the power from the machine. Remove the cover and the mains lead is directly connected to the fuse. The fuse id blown MUST be replaced with an IDENTICAL fuse.
