Have you tried any of the other controller pads for the run button? meaning take the button 1 and 2 pad and press it over the run contacts on the pcb to see if it works. If it does then you need to clean your Run button rubber pads. I like to use a small piece of sand paper to lightly rub across the little black circle a few times. I've tried cleaning with various things but that never seems to cut it. Sand paper always works. To be clear I am talking about wiping the rubber circle with sand paper. Not the controller PCB.
