I received this range from a friend, so not sure of what age it is. I was trying to bake with it, but the lock light began to blink, the oven door locked up, and the bake function is not working. I was able to get the door open, but the door lock switch is stuck out. I tried pushing in the oven light button and pressing cancel at the same time (I saw that in a prior posting). Another code "dr" also came up. Any ideas?
Model Number: FGFB74BJBB
I didn’t mention in the post that an "F9" code also comes up with a loud beeping sound.
