The plate inside the oven won't turn anymore - Magic Chef MCD1110ST Microwave Oven

The motor for the rotator is bad. It has to be replaced.

there is a belt on bottom its broke

Have a shop look at this---there usually is a recessed safety switch inside the jam that will prevent the unit from working with door open--sounds like the problem may be with it.

replace or rewind the transformer.

Microwave Oven Basic Troubleshooting Tips

Replacement of the turntable motor should be carried out by a qualified appliance repair service.

YOUR SAFETY IS PARRAMOUNT!

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.

Usually the sparks are from exposed metal. Clean the oven, and the table and anything else you can inside. Then just try nuking a cup of water. That gives it something to work with and it won;t make any sparks itself. Then just see if the sparks are gone. If the paint has come off inside the cavity and exposed some metal you can get sparks but that usually means replacing the microwave. If its caused by an object or buildup then a good cleaning stops it.

check and see if the turn plate is on correctly

How old is the unit?
Is the 'Plate' clean?

PLease open the housing of turn table motor at bottom of the oven and check for the AC input voltages on motor terminals as specified on sticker on motor. for no heating please check fuse between high voltage transformer and high voltage capacitor. Also check high voltage Diode and Magnetron.Please please don't try to measure voltage on terminals of magnetron.
