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.

There is a fuse inside the chassis that can be accessed by removing the 4 side screws and the 6 back screws on the chassis cover. First unplug the unit then remove the 6 screws securing the cover to the shassis. Once the screws are removed lift the rear of the cover about 10 to 15 degrees and pull to the rear. The chassis cover will then come off. NOTE: There is a large capacitor inside the chassis that will stil have a charge. Make sure to avoid it when reaching inside the unit. Follow the power cord from where it enters the chassis to the end terminals. One of them will terminate at the fuse holder. Remove the fuse, obtain a new fuse of equal value amd intall same. Plug the unit in to see if you get some from of power be it a light inside or the contral panel lighting up. If it is just the fuse and you see signs of the unit having power once again unplug the unit and re-install the chassis cover.. Make sure that the cover interlocks on the front of the chassis properly. All mating surfaces should appear flush. Re-install the 6 screws and retun the unit to service. If nothing happens please reply to this post.

GET THE OVEN NUMBER AND SEE HOW MUCH THE TOUCH PAD COST, SOME TIMES THE TOUCH PAD COSTS AS MUCH AS MICRWAVE OVENS NOW DAYS

THe microwave has to be removed from the wall and then the outer cabinet has to be removed to get to the bulb. Do not do this with the unit plugged in and do not do this if u don't know how to work on a microwave as there is a shock hazard.

Microwaves should only be worked on by fully qualified repair people and my advice to you would be to bring it to such a person,they can be dangerous to work on due to the presence of such high voltage, other than changing a light bulb any other repairs are out of limit.

One or more door switches is bad, or the switch mount is loose or broken. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
