I set my Maytag wall oven to self clean four days ago. When it was almost done, the display went blank. I didn't think much about it at the time as I was busy. That evening I went to open the door and it wouldn't open. Then I realized that there must be a problem and the display stopped because if a power issue. The next morning, I tried to open the door a again and it was still locked. My husband checked the power to the oven which was working then he tried to reset it. Nothing worked. We can't pull the oven out of the wall because the screws that hold it in, are between the door and wall. How do we get the door unlocked? There isn't a manual locking handle to use.
