If it runs with the door open it is a door switch problem. I had something similar on the office microwave and it turned out to be a bent mount for the door switch. It was made out of cheap, flimsy metal that deformed and let the switch bind. I replaced it with a Kitchenaid commercial model. It's built like a tank, but cost almost $400.
There are some really cheaply made microwaves out there. The internal electronics on the cheap ones aren't much different than the are on the more expensive ones. More expensive ones have fancier controls and more robust latches and hinges. When checking out new microwaves, look for a good strong "snap" when the door closes and check to see if the door moves once it's closed.
I have had a Sharp in my kitchen for 8 years that has held up well.
