FIXED - Cost zero - Thank you all for your comments. My RCA low cost microwave table kept turning when door was closed and nothing else was working, no matter what button I pushed, I could not reset . I used a small Kid's dry paint brush and cleaned the holes (with microwave unplugged) (where the door things go when door is closed and plugged it back on and voila it is working like before . I am no tech so this is the solution I came up with and it works...
