Latch handle was broken, so door wouldn't open properly.

Don't feel like giving lots of detail. If one can't figure this one out on your own, then you need to call a professional repairman to do it for you. At this point you will need to seriously reconsider your own manhood. This job only requires taking out several screws to remove the control panel and the screws and connected wires to remove the latch itself. Installation is the reverse. VERY easy.
