Microwave turntable wont turn

broken or misaligned door interlock switch is most likely

bad motor in the turn table or it is gummed up

Hi,
if the turntable is getting hot it means that the microwave is working but as the turntable is not turning , it means the adjustment of the door lock of your microwave may have become improper due to use.may be it got damaged.
call the technician of samsung microwave ,he will open the cabinet of microwave and make the adjustment of door lock proper.
Thanks

Repairs are expensive. New microwaves are cheap. But you don't have to spend a dime on either. If your microwave turntable stopped spinning, here's an easy way to try and fix it. And all you need is some warm, soapy water and your own two hands. You don't have to be an appliance expert to troubleshoot a seemingly broken microwave turntable. You might find that all your little Zappy needs is a checkup and a good, thorough cleaning. If you follow these steps and find that your microwave still isn't turning, it probably means the motor has spun it's last spin. Then it's time to retire old Zappy. Unplug the microwave. Safety first, kids. Remove the glass tray and the circular turntable guide. Wash them both in warm, soapy water to get rid of anything stuck. Pay special attention to the rollers on your turntable guide, making sure they're able to spin freely. Clean the internal cavity. Make sure to check your microwave's center cavity to make sure it's free of movement-hindering (and gross) leftover food. Check that the drive bushing is working. Make sure that the drive bushing, the plastic mechanism in the bottom of the microwave's interior that the glass tray turns on, isn't worn out or split in two. If it is, you'll need to have it replaced. Put it back together. Put the turntable guide back into the circular groove. Place the glass tray turntable over the turntable guide and onto the drive bushing. Adjust until the drive bushing should fits perfectly into the grooves of the glass tray. Test it out. Zap a mug of water for a short bit to see if you fixed the problem. Do not run the microwave without anything in it.

The turnable motor must be replaced, go to www.ebay.com Type: make and model of microwave oven, refine search to turntable motor.

Probably a bad door switch. See this file.

Yes the microwave is safe to use, without the turntable working.

The turntable is a seperate intenty from the microwave itself, I would presume that the switch that turns off the turntable when the door is opened needs replacement.
