I ordered both hinges (if the nylon roller was bad on the left, it was probably going to go bad on the right side as well). The web site was easy to navigate, order process simple. Hinges arrived quickly. Slide the oven door up and off. unscrew the three screws for the hinge. You need to then pull up with some force (there is a big spring in there), and twist the hinge to get the last bit out. I used a hemostat to hold the spring and keep it from falling back into the hole. removed the hinge from the spring, noting which hole it went through. installed new hinge on spring, released the hemostat and reinstalled hinge (just do it all in reverse). Repeat for other side, slide door back on. Now door opens smoothly and easily.
