the serving door for icemaker is not closing. I do not have a manual for it so I can't tell how to take it apart to see what the actual problem is. It seems like there might be a spring or something broken. It looks like if I hold the ice chute and lever up the door closes, but I can't stand there 24/7 holding it closed. Please don't laugh at me if I totally described it wrong I'm new at trying to fix appliances.
