No Power, Unless door is slammed.

1st I love my microwave and would like to fix & keep.
With that said. This is the problem.

When you push any buttons to microwave, All that happens is the light comes on but does not microwave.
But if you open and slam the door, then it works fine for about 5 times until you slam it again.

What is wrong with it? Can it be fixed?
