Replacing outer door frame

I also had the same problem with my GE spacemake xl1400. the bottom of the outside door frame cracked and i replaced it with a new one from you. when everything was put together, the inside light stayed on and the microwave no longer was working. it did work before the repair. any suggestions, it appears the latch is not catching now but when i try just the latch by itself without the door, then it works.. so confused. please help if you have any ideas, thanks
