Samsung microwave auto starting

Question

Microwave starts on its own. I have removed control panel and peeled back the first layer of the keypad membrane but cannot locate a part #.

The only part # I can find is molded into the plastic on the rear of the control panel. It is DE72-00130A which Samsungs parts database identifies it as a CONTROL-PANEL ABS,NC2000-2(1.0CUFT).

I am assuming this is the plastic only and does not include the keypad membrane since it is only $11.75

Any help with finding a part # for the membrane would be greatly appreciated. Thank You.
