Oven control buttons don't work

This wall oven says Amana on the front of the unit, but Maytag on the ID tag, so I am not sure of what brand I should have listed. I am guessing at the age.

Several of the flush mounted push buttons have stopped working making it impossible to set the oven temperature. I have pulled the front control cover off and removed the control board. The push buttons seem to consist of pressure sensitive sensors on 2 ea long plastic ribbons that are sandwiched between the front plate (with the numbers on it) and a stainless steel back panel that is tack welded to the back side of the front plate. Because it is tack welded, I can’t remove the ribbons. Can this be fixed?

Thanks

Hi.

Unfortunately, the model number you provided doesn’t come up in the research.
