We have two wall ovens - one a Whirlpool the other a Kitchen-Aid - strangely enough both use the same hinges. After paying over 175 each for the repairs I was shocked to see how quickly they failed. Within 8 months one had to be propped closed with a broom handle and the other with a stool just to keep the doors closed so my wife could use the ovens. You will need something like the pins shown in the pictures as there is no flip over lock everyone tells you to use to remove the door.
Pins or substitute required to remove door as there is no locking lever as on other makes for other ovens.
Note: pins go into the hole that is below the body in this picture.
