Re: LG MS-1943ALT Micowave not working, light, fan and...
From the decription that you have provided, the magnetron is highly suspect and is the most expensive part to replace, cheaper to replace the microwave oven in the long run.

sounds like the drivr belt is worn or sliping, is the plate turning freely on the runners if there worn they can cause the plate to drag that can also cause the this problem
If everything is working normally, except for heating, the likely cause is the magnetron. Microwaves can be dangerous to work on, as the site below points out. If you have an ohmmeter, it is possible to check the magnetron, but be certain to follow the precautions outlined at the webpage: http://www.gallawa.com/microtech/mag_test.html
If the oven is doing everything else properly (light comes on, fan runs, turntable goes around) but there's no heat, you may have a failed magnetron tube (the microwave source). There's also a relay that controls power to the tube that may not be working correctly, or the control circuit board is bad. It's also possible one of the door switches is not working (so the oven thinks the door isn't closed), although this usually keeps the turntable and fan from running.
Microwave oven service is not for do-it-yourselfers. There are potentially deadly voltages present even with power off, and a chance of microwave leakage if repairs aren't done properly. Let a professional give an estimate to repair it, or just replace it if it's under $100. (When I was servicing these things it wasn't unusual for a repair to cost over half the price of a new one. That's one of the reasons so few shops still work on small appliances.)
Possibly the light bulb has blown, which has blown on a track on the board which has taken out the turntable motor and the fan. Also, there could be a problem with the door switch.
tell me about it. try not to buy ge. the sevice charge was almost 200$. it still doesnt work. it has been over 30 days. so they want me to give them another 79$ just to come out again
Could be the relay, an internal fuse. With the power off, open up the key panel and search for a fuse. Also, there are thermo sensors black, diameter of a dime and 3/8 inch thick with two wires. Check the fuse and replace if necessary. The thermo can be jumped out to test. Remove the wires, use a paper clip between them and tape it up. Briefly turn the unit on. Replace if it works now. The thermo is generally clamped to the wall of the oven behind the key panel. Never run without the thermo sensor.
