How to Troubleshoot & Replace Bosch AP4017056 / 00144648 Wall Oven Bake Element

Replaced the lower heating element and heat sensor in a Bosch Double built in oven. It took two people to slide the oven out and set it on stand so that we did not have to lift it. Changing the element was easy as well as the heat sensor. Less than 15 minutes after the oven was out. Fortunately, I did this project because upon pulling the unit out we discovered that the original installers had been very negligent in the electrical hookup which was too short, pulling out of the box due to an improper connector and they simply put electrical tape around their laziness. I rewired the unit with a proper cable of the correct length and connectors. Everything is now working properly and safe. 

Replaced the sensor and bottom heating element just to be safe. The sensor can be changed from the front, the heating element requires you to move the oven out of the wall. There are clips you need to hold down when installing the heating elements but otherwise it's pretty straightforward. The oven no longer stops at 285 but it's still about 25 degrees lower than the setting. This is ok as long as it's consistent and it has been. Think maybe a circuit board needs changed but these replacements at least allow us to use this $1800 oven. 

Replaced the oven bake element and the sensor. I don’t think that the sensor was faulty, but replaced anyway. The replacement was fairly easy, but there are 2 clips that hold the element and the element’s front crossbar will snag on the clip that holds the rear cross member. To solve this and prevent the rear clip grabbing the front cross member, used a saw as a guide to cover the rear clip and act as a ramp for the element. Once the front cross member has passed the rear clip, the saw can be pulled out. A long ruler could be used instead.
