First you will need to answer a few quick questions between yourselves.
There are bits inside there that will happily kill you days after it has been turned off. (some even weeks)
For the cost of a replacement in this case, it's not worth it.

i think you have a welded controller, either a digital one or a mechanical one. microwave won't run unless you switch it to run. the door switches are safety switches to turn off the microwave once you open the door. if you have a digital controller, you could have a welded relay, if you have a mechanical timer, it could be a welded contact at the timer. another thing is that it should heat what ever you are heating. if it is not heating, check if it has a fuse and if it is busted. some fuse are installed to protect only the magnetron that is why the light and turn table are still running. if there is no fuse to the magnetron, then check the diode from the capacitor to the ground. it could be open. if not then you can have a bad magnetron. i hope i was able to help.

yes! , this is dangerous , be cause it sounds like the magnetron that sends out the microwaves may not be controlled , thus heating the outside and will be sending waves out of the microwave!
you will need a qualified electronic repair shop to deal with this, these microwaves are very dangerous and that unit should not be used untill it has been fixed , for the safety of you and anyone who uses or is around when in use.
these microwaves that are sent across the air to heat the food is burning it and it can do the same to you or any one who is around it while in use
even when in working normal conditions the waves still leak out some , so i always walk away when heating food in the microwave and i advise others to do the same
so the magnetron will need replaced and maybe another component but it needs to be tested to make sure nothing else is damaged also
hope my help has pleased you and that you can give me a fixya rating( all others hurt our rating) as i work on these and i know the symptoms that happen and the causes
again hope you can give me the fixya! , thanks , and if you need any other help, just ask me!

Test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
The diodeand capacitors can be tested. The capacitor must bealloweddischargebefore testing, or you risk to get electrocuted, evenifpower is off.Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
Parts must be tested to find out what is wrong.
Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.
Regarding parts, contact the seller here to purchase parts.
You can also order from MicrowaveSvc , they also provide parts.

Your signs point to a failed power tube. First though, does it defrost? If it does it is an electrical control problem. If it does not defrost, do the following.... With the power unpluged you may want to remove the outer cover, ( screws at back ), and locate a shiney metal box. That box is shielding for the power tube. Get the part # from the tube and replace. You could check price and availability at www.avnet.com . Make sure you replace all of the shielding exactly the way you found it. VERY VERY IMPORTANT!!!!!
