I have a Monday night football game and it works good. But if you get both balls locked then the solenoid to push the last ball out keeps engaging and won't stop even when the ball came out to the plunger. The solenoid keeps firing again and again and again........ I tried to put a fourth ball in the game but that doesn't work, it fires two balls to the plunger. What could be wrong? It sucks because I can't go really far in the game when that happens. Plus I don't want to break the solenoid. Any suggestions???

Thanks got it fixed. It was outhole 3 and I put a new switch in it!
