I presume if it has a turntable that works--there is a safety switch if not that will prevent heating.

Possible causes: bad diode, bad inverter board (diode could be there) that powers the unit for cooking and also a bad Magnetron.

SOURCE: Samsung microwave oven turntable doesn't turn

Yes it just will not cook or defrost very evenly. It is not dangerous however.

Probably the motor or gears that make the turntable go are worn or burnt out.

SOURCE: I have a samsung smh7187 microwave over the range

I would suspect the oven cavity's thermal cutout / thermostat, the magnetron's thermal cutout / thermostat, and/or the fuse.

SOURCE: My samsung microwave oven is

if your microwave does everything you have described , and you can hear the cooling fan running as well after you press the start button , you probably have a faulty wave guide. The wave guide is also called a Magnetron Tube. It is the main part of the microwave which produces the microwave energy . If this part is not functioning it is best to replace the entire unit, rather than have it repaired .

SOURCE: Does the exhaunst fan turn

Some interesting reading on page 8 of the owner's manual:

"Boilovers cause smoking and greasy spillovers that may ignite and spread if the vent fan is operating.To minimize automatic fan operation, use adequate sized cookware and use high heat on surface units only when necessary."

And on page 20:

"If the temperature becomes too hot around the microwave oven, the fan in the vent hood will automatically turn on at the LEVEL 2 setting to cool the oven. The fan will automatically turn off when the oven has cooled down sufficiently. This is an automated process and cannot be turned off. The fan may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. The Vent Fan will only operate in 1~4 levels modes while the microwave is working."

"Using the Vent delay off button
1. Press the Delay Off button once to turn the fan off after 1 minute.
2. Press the Delay Off button twice to turn the fan off after 3 minutes.
3. Press the Delay Off button three times to turn the fan off after 5 minutes.
4. Press the Delay Off button fiour times to turn the fan off after 10 minutes.
5. Press the Delay Off button five times to turn the fan off after 30 minutes."

If for some reason you don't have your owner's manual, you can still download it free here.

Sharp microwave model R-530EK won't turn on. problem in door latch?

You could download the service manual from this website and go to page 11-1 for instructions on removal of top cover.You should then be able to access the latch from the side as it is under the control panel.

The manual also provides repair procedures on different problems.
You have to be vary careful with microwave oven interior and at all times when working on it the power chord should be taken out. There area also high frequencies and precaution must be taken and never turn on without the top cover back in place.

The whole power on microwave is off.

I suppose you checked the outlet for power. There is a (15 Amp slow blow) fuse inside the oven. that could be blown. If that is the case, just replace it. If, after replacing it, the oven works Ok you will have taken care of the problem. If, however, the fuse keeps blowing when opening / closing the door, that means that there is a problem with the door switch sequence. If this seems to be the case and you want to get into that, I would have to walk you through it, step by step. I would need to find out how to do that as per FixYa rules.

I don,t know how to use the microwave to boil water or warm food quickly.

Microwaves differ in power so you need to determine how long it takes your microwave to boil water. Great care should be taken as because if left to cook too long, water can become super heated and cause serious injury.
To determine how long yours takes, put about a cup of water in a microwave safe mug with a handle in the center of the oven and run it for about 1 minute. Remove VERY CAREFULLY and check the temperature with a meat thermometer. Repeat until you get the water up to about 180 degrees F. Note the number of minutes and use that going forward.
