HBL57M52UC (01) Bosch Wall Oven - Instructions

Replaced the wave cover. Unscrewed existing cover that is at the top inside the microwave. Screwed in the new cover.
Took about 30 seconds to do. Bosch service wanted over $100 for a service call plus parts and labor. Did it myself in seconds for under $10.

First, cut the power and remove the oven from the cabinet.

The bake element is accessible from the back and sits in a drawer.

As someone else said, you have to use pliers to bend the cover of the drawer, you will make some damage to the cover, but there is nothing you can do about it.

Make a note of what wire goes to the right and to the left so you can plug them back like it was before.

When you replace the bake element, make sure you insert it in the straps so it won't wiggle when it heats.

To close the cover that you bent, you will need a helper and push really hard.

Replace facia panel. Turn off power to the oven. Remove oven control knobs by inserting finger tips under each side of the knob and pulling. Open oven, remove mounting screws. slide the oven out a few inches to allow clearance for the removal of the facia panel. Remove 3 torx screws under the bottom of the facia panel. The wiring harnesses for the LED temperature display and touchscreen are very short and must be disconnected in order to remove the facia. Slowly pull out the bottom of the facia panel taking care not to damage the wiring harnesses. Locate the wiring harness connections and disconnect. Lift the facia panel up and away from the oven. Carefully remove the LED temperature display from the back of the facia panel touch screen. Installing the new facia panel: The LED temp display wiring harness is very short and difficult to connect with the LED display installed on the new facia touchscreen panel. For this reason connect the wiring harness to the LED temp display before installing it in the new facia. Once the wiring harness is connected to the LED display, place the facia panel in position and reach under, align the LED display with the touch screen panel mounts and snap into place. Connect the touchscreen harness, position the facia panel and replace the three screws. Secure the oven in place, replace the knobs, and turn on the power.

I watched a YouTube video that confirmed the diagnosis of failed safety switch. Order the switch and the housing as recommended (because the housing is cheap plastic and as it ages it wiggles too much and no longer holds the switch correctly).
With help of my sons to get the microwave out this was an easy repair. I recommend taking the left side panel off (involves removing the left frame rail as well, but makes access SO much easier).
Bottom line: no need to replace a $1700 microwave. No need to replace several appliances to go with a new brand (that was wife's idea for $4500!).
Nope! $15 of parts from partselect.com (plus shipping) and we are cooking again! THANKS!

After going to a local parts store to get the correct switch, I replaced the right door switch. The correct switch is a normally open switch. The one shipped to me was a normally closed switch. Either Bosch provided the wrong description of the part required or someone at partselect needs to check the part stocked.

Took the one out of the box and take off the back plate and detach the sensor

installed new front glass panel.
installed thin magnetic catches on each side of door
