Tufting Machine "auto firing" (machine running without pulling the trigger)

Dont forget to rotate the bearing arm. Should be a quarter gap between bar itself and sensor pads.

Hi I could use some advise, I have a problem where my gun sped up rapidly to full speed and instantly fires without pulling the trigger at all. Is this still a blown capacitor?
