The door panel and grille vent are plastic and thay both cracked and fell apart due to cheap plastic parts from GE.

Removed the screws at the top of vent and took the vent off and then removed the door by lifting it off the hinge. I had to break the old plastic door frame to get it off, but since it was no good anyway it didnt matter. Then I put the glass in the new frame put the handle on it and snapped the frame on to the door and put it back on the door hinge and then put the new vent on and screwed it down and closed the door. Job was not to hard at all.
