bullfrog1986 Posted May 2, 2015 Share Posted May 2, 2015 I recently purchased a tabletop snack machine, 2 shelves 15 coils total. It worked okay at first, but now the selection buttons are out of whack. The coils are labeled A-0 to A-4, B-0 to B-9. When making a selection, instead of pushing A or B and then a number, it now makes a selection off a single button as follows: 1--> A-0 2--> A-1 3--> A-2 4--> A-3 5--> nothing 6--> nothing 7--> nothing 8--> nothing 9--> B-0 A--> B-1 0--> B-2 B--> B-3 Does anyone know how to fix this problem? photos available at https://plus.google.com/photos/106257839731657567021/albums/6144363299591278993 Link to comment Share on other sites More sharing options...
AZVendor Posted May 2, 2015 Share Posted May 2, 2015 Your link says "You have no permission to view this album." What is the model of the machine? Your problem sounds like a bad keypad with a failed matrix but it could be a bad logic board. I would say the keypad if this pattern repeats itself.

bullfrog1986 Posted May 3, 2015 Author Share Posted May 3, 2015 Ok, I fixed the permissions for the pictures. The only reference I have for the model number is on a sticker on the back: Avanti Vending Machines, Model NO RCS-15-EP. I think the problem is in the board and not the keypad. I just pulled the board off the door and used a wire to jump the pinholes where the keypad plugs in. It is behaving exactly like if I was pushing the buttons.

bullfrog1986 Posted May 9, 2015 Author Share Posted May 9, 2015 Does anyone know how to repair this board or where I can obtain a replacement? Link to comment Share on other sites More sharing options...
AZVendor Posted May 10, 2015 Share Posted May 10, 2015 Never seen one or heard of it. It is some kind of contract-built machine that must have had very few units sold. I've studied the board and the machine and the only thing I can come up with is maybe it was built by Polyvend. Unfortunately Polyvend is gone and the board they made for their table top machine is different than this one. I'm sorry, but it's time to retire this orphan and get a better machine.

orsd Posted May 10, 2015 Share Posted May 10, 2015 http://www.avantivendingmachines.com/show_Product.asp?ID=12173 If is more than a couple hundred for a board just scrap the machine, good quality full size machines are only a few hundred used. Get AP, National, Crane, AMS or Rowe, all are great and Az vendor will have parts for them. Link to comment Share on other sites More sharing options...

It should say "Rebranding Existing Vending Machines so We Can Overcharge for them since 1974." Link to comment Share on other sites More sharing options...

The machine looks like a RPD which are manufactured in the USA by Raddatz Product Development but has been re-branded by Avanti Vending You could try & contact them.... http://www.rpdvending.com/index.php/contact-us Link to comment Share on other sites More sharing options...

AZVendor Posted May 11, 2015 Share Posted May 11, 2015 Yup, he did. I knew the parts looked familiar but couldn't think of the RPD name. Link to comment Share on other sites More sharing options...
bullfrog1986 Posted May 12, 2015 Author Share Posted May 12, 2015 I just saw in an old thread http://vendiscuss.net/index.php?/topic/13934-help-building-a-home-made-vending-machine/ about using an arduino to build a control board. Does anyone have an idea on what this would cost, and can anyone walk me through assembly and programing? I did use the contact form on RDP's website, but haven't received a response yet.
