Problem with GE Turntable Microwave, when I press the button in half-way it turns on. Otherwise vise versa. Is this common on GE's?

It is not user-serviceable, since it is very dangerous to work in them. I'd suggest buying a new one or have it serviced by a professional.

Take a look at this:
How microwave ovens work - YouTube

It explains how they work, but I don't recommend working in it at all.
