Why wont the button on my microwave open the door

I have a kitchenaid microwave. I dont know the model number. I push the button to open the door and it wont open. The button is broken. Can i fix it myself or do i have to take it to get checked.

ANSWERS:

Your problem is that to replace or repair it you have to get it open. It might be cheaper to just replace it, if it a stand alone.
