Replaced hinges. It was a bit tricky, as you first have to open the door fully and move tabs to allow for removal. I had difficulty locating the tabs, until I exposed them by manually pulling the door away from the hinges. I then closed the door to the 'broil' position and pulled off the door.
Removed the 2 screws holding each hinge. Struggled to remove hinges as they were damaged and are a tight fit. Installed new hinges which was somewhat difficult with assistance from rubber hammer. Then found I couldn't install screws. Removed hinges and found that the screws are self-tappers, but wouldn't go into hinges as the screws were worn. I then used a 8-32 tap to tap the hinges. Reinstalled hinges and door. I should have purchased replacement screws.
WEAR WORKING GLOVES, AS THE HINGES HAVE SHARP EDGES!
