Purchased proper hinges. Lifted oven doors off the hinges. Removed screws securing the oven to the cabinet, then slid out the unit from the cabinet far enough to access the hinges. Then removed trim to better access the hinges. Then removed the screws holding the hinges. Then installed the new hinges, secured them with the screws, then reinstalled the trim, then slid the unit back into the cabinet, and secured it in place with the screws. Finally, I placed the oven doors back on my hinges. I did turn the power off to the oven while I worked in it. The door works at like new now.
