Samsung microwave oven turntable doesn't turn now. Is it ok to still use to heat/cook food ? What is the problem with it ?

Even if the turntable isn't turning, the oven should still heat the food but it will be uneven cooking. I would suggest that the unit is not "microwaving" This is usually the high voltage capacitor, fuse or diode failure. You will need knowledge of how microwave ovens work and specialist tools to test these. If you don't, I would suggest you get a tech who does. There are extremely high voltages in microwave ovens.

It should be ok to use as is, though you may have to stop it and turn certain items to ensure even cooking/heating, especially frozen foods, or larger items. You may be able to fix the turntable by doing a "deep cleaning" on all it's components, you might just have some old food residue blocking it. Hope this helps.

Most microwave ovens have a "stirrer" blade run by a small pancake motor to help avoid standing waves and hot spots inside the microwave cavity. And most modern microwave ovens have a turntable to turn the food, to provide even more even-distribution of heating.

If it is not cooking and the turntable will not turn, this sounds like the secondary interlock switch is bad. Almost always this failure is caused by opening the door when it is in a cook cycle. Pushing the stop button before you open the door will prevent this in the future..

you have a couple bad switches

The manufacturer has set the rotational plate in motion at the same time the microwave tube is energized. They work together as a team. At no time should the plate be idol, unless you remove it completely, and then only the center spindle will turn by itself. It is possible for the rotational spindle in the center of the oven to break, but that is unusual unless some sort of pressure (like stopping it when it was moving) was applied. Also, it has been reported that some individuals tend to put items with too much weight or too large for the oven to manage; thus damaging the rotator. As long as the oven still provides Microwaves to cook your food, it is still OK. Years ago, there were no rotating plates and using the energy was all it took to get the job done. For even cooking, just manually stop the oven at times and turn the food to avoid over heating in one spot.

This is a sure sign that the MAGNATRON unit has went out on your oven and will need replaced! (This is what cooks the food!)

Thank You!

This is normal. That's why I always recommend to my customers that the food be placed slightly off-center on the turntable. An analogy I refer to is stirring paint: If you stir paint with a stick by simply rotating the stick in the center of the can, it's far less effective than pulling the stick around an imaginary circle halfway bewteen the center and the edge.
