Weird clicking inside vacuum

[Waxman]

One of my vacuums intermittently clicks constantly and I can't figure out why. I have a slug buster two coin acceptor and an IDX timer. The little metal piece that detects the coin when it goes through the chute is constantly clicking back-and-forth randomly. When I move the face plate a certain Way I can get the clicking to stop but it always seems to start again at some point. I thought it was a coin jam because it's the same type of sound that many of the coin acceptors make when there's a coin jam but there's no coin jammed. Any ideas?

The coil on coin acceptor is bad or going bad. Install your spare coin acceptor and send it in to Parker/Slugbuster and they'll fix it.

If the potentiometer is failing it will do what you describe. You can try turning the sensitivity all the way up and down and then back where it was set. Sometimes that fixes it permanently, sometimes just for a few days. Keep the covers closed.
