We have the complete service manual on our site: http://www.microwavedisplay.com/r930ak_aw_sm.pdf It contains all the safety, disassembly and part information you should need. You can order a new turntable motor (and likely a new "motor packing" grommet, and perhaps a new coupler) at Tritronics at http://www.wehaveparts.com
The solution was good and the site for the diagrams was very useful but my question about the leakage of the radiation if it is opened wasn't answered.
The TT motor coupling has melted at the shaft. You can be sure of this if the TT tray free spins without any resistance. You will simply need to replace the hard plastic coupling.
Replacement of the
turntable motor should be carried out by a qualified appliance repair
service.
YOUR
SAFETY IS PARAMOUNT!
Attempt
this only if you are competent.
But here is a basic method if you are
mechanically minded and have electrical safety knowledge.
The motor assembly is fixed to the base
of the oven usually with two screws and access is obtained usually by
removing the inspection plate directly beneath the motor. It is
usually a plug in synchronous motor that revolves at a few revs per
minute but the plastic cogs in the motors gear box fail and the motor
assembly must be replaced. They are fairly inexpensive and obtainable
usually from a domestic appliance repair shop.
If you feel
confident, disconnect it from the mains power, remove anything in the
cavity and turn it upside down if it is a tabletop model, a little
more complicated if it is built in!
Remove the inspection plate,
sometimes it must be cut out with sharp cutters, and disconnect the
motor. Remove the motor and go and get a new one. Fit the new motor
and fit the inspection cover back on the base by turning it to fit
and using an extra screw fix it then put the microwave back in its
position. Plug it back in, with the turntable and plate. Put a cup of
water on the plate inside of the oven and heat for 20 seconds to
check the plate goes round.
Hope this helps.

There is an access plate on the bottom of the oven which covers the motor. It comes off easily and the oven cover can remain in place.
The coupler is melted at the motor, can I get the parts?
