is this a single oven or a double oven?
A freestanding or built in oven?
ok if you turn the power off ,with a long screw driver or a clothes hanger (cut it to make a long wire )
in the center of the oven just above the door is a grill in the center you will see a goldish color dimed size silonoid about 6 inches back from the door front ,,,just push it back and pull the door open.
ok the model number helps
This is just a manual latch .
So move it allthe way to the right till it stops (then push it another inch or so )
then try to unlatch to latch assy (the arm is bent!!)you have to bend it back
