Thomas lindsey Posted July 22, 2017 Share Posted July 22, 2017 I have a drink vending machine that when you put a dollar in you hear a little click and nothing happens. It won't vend anything and it wont give you your change. I've replaced the bill validator, the coin mech, and the adapter for the coin mech and bill validator. Idk what else to do. Any suggestions?

Snickers Posted July 22, 2017 Share Posted July 22, 2017 Sounds like you have an old single price can Machine and that you need a credit relay. Looks like an ice cube that plugs in usually clear or black plastic. Link to comment Share on other sites More sharing options...
AZVendor Posted July 22, 2017 Share Posted July 22, 2017 Nope. Rarely a credit relay problem. First unplug the machine (there is 110v on every wire) and look at the selection switches to make sure that there are no loose wires by any switch. Then look at the wire side of the connector the coin mech plugs into and push each wire up into the socket in case one has come out. Then look at all your vend motors. You're looking for one motor timing cam that has both motor switch arms in one notch or both on the high side of the cam. Both in a notch is probably a bad motor brake. Both on the high side is a jammed column. Tell us the model number of your machine found on the serial number plate on the left side of the outside door.

Thomas lindsey Posted July 26, 2017 Author Share Posted July 26, 2017 I need to clarify a little bit. It will vend flawlessly and give change back when you pay with change. When you try to pay with dollars is when all the problems start happening. And also the change is building on top of the coin mech. Link to comment Share on other sites More sharing options...
AZVendor Posted July 27, 2017 Share Posted July 27, 2017 Change laying on top of the coin mech is a coin chute alignment issue or a broken coin chute. The issue with dollar bills sounds like the coin mech isn't handling the credit properly. Email me at rbepic4gatgmaildotcom if you need an exchange coin mech or coin chute.

Thomas lindsey Posted July 28, 2017 Author Share Posted July 28, 2017 I've replaced the coin mech twice and they all are doing it. Link to comment Share on other sites More sharing options...
Apple Leisure Posted July 28, 2017 Share Posted July 28, 2017 Is it a single price machine as Snickers suggested? Link to comment Share on other sites More sharing options...
Thomas lindsey Posted July 31, 2017 Author Share Posted July 31, 2017 Yes it is a single price machine Link to comment Share on other sites More sharing options...
AZVendor Posted July 31, 2017 Share Posted July 31, 2017 Then you may have a motor switch problem or a loose wire in the coin mech socket or the credit relay socket. Link to comment Share on other sites More sharing options...
Thomas lindsey Posted July 31, 2017 Author Share Posted July 31, 2017 Ok I'll try to see if there's a loose wire today. I hope that's it Link to comment Share on other sites More sharing options...
AZVendor Posted August 1, 2017 Share Posted August 1, 2017 Do it without power applied because all the wires have 110v on them. Link to comment Share on other sites More sharing options...
