That would be a shorting membrane keypad.On most of these, the membrane keypad is not available as a separate part, so
you would have to order the control panel frame assembly which comes
with a new keypad.
It's actually a pretty easy do it yourself job.
A video is available
here showing how to remove a typical over the range control panel assembly in under 5 minutes.
Next, disconnect the keypad strip as shown in the photo below, then
remove the screws that hold your circuit board in the old frame.
Then carefully (since the display is made of glass) move your
circuit board to the new frame, and reassembly is the reverse of
disassembly. You can find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven
here.
