Dismount door from oven, by removing screw that secures the lock tab in place for each hinge. Lift door up and out. Door weighs about 20 pounds. Lay face up. Remove 6 screws, 3 on top, 3 on bottom. Remove door face. Remove one screw that secures the hinge assembly to door. Make note of which hole that screw came from. Lift off. Install new hinge in reverse order of removal. Reattach door face. Install door back on oven, and replace the lock tabs. The door will not close fully, until you pull the pin that fixes the hinge partially open. Just pull back on the door, and use a pair of needle nose pliers to get it out. The pin is there to make it easy to install the hinge assembly. Recommend you replace both hinges at the same time. Unless you want to do this job again. They last about 10 to 12 years.
