Vending 2019 Posted August 25, 2022 Share Posted August 25, 2022 3 Selections in the same row are double vending/not cycling correctly. One selection will even give the change back afterwards. Harness has been changed, issue is still there. Thanks in advance. Link to comment Share on other sites More sharing options...
cvending Posted August 25, 2022 Share Posted August 25, 2022 Try switching shelf with one above or below and see if the problem stays with the shelf or not. If it stays with the shelf you have either a bad harness or bad motors. If it stays at the same location, you may have a bad tray board or motherboard. You might also try to do a RAM Clear and rest the machine 1 Link to comment Share on other sites More sharing options...
Gizmo Vending Posted August 25, 2022 Share Posted August 25, 2022 Do any type of programming before this started happening such as price changes? Is this a machine you just purchased and you noticed it was doing this? Have you checked the free vend settings? This machine also has a function to test the sure vend sensor and can give you diagnostics as well. 1st thing to check is if there are any errors.

Vending 2019 Posted August 26, 2022 Author Share Posted August 26, 2022 No programming right before this started happening. Ive had this machine for about a year in a high volume account and haven't had much trouble outside of changing a couple harnesses. This is great advice though, thank you. I'm going to check for errors Link to comment Share on other sites More sharing options...
AZVendor Posted August 26, 2022 Share Posted August 26, 2022 I'm with a bad tray board as well. Link to comment Share on other sites More sharing options...
Vending 2019 Posted August 30, 2022 Author Share Posted August 30, 2022 I switched out shelves, harnesses, and motors on the selections in question. Problem still persist, I'm ordering the Tray Board. Appreciate the help! Link to comment Share on other sites More sharing options...
Vendors Tech Posted August 31, 2022 Share Posted August 31, 2022 I would partially concur with replacing the tray board, but since you said that money is returned sometimes too (I assume after a product has been successfully been delivered), I would highly recommend performing a RAM clear before replacing any parts, as I don't think a bad tray board would cause money to be returned. Here are the RAM clear instructions for your machine: A. Machine must be in stand-by or Ready mode. If not, press “EXIT” B. While holding “EXIT”, press “UP ARROW” C. Press “Edit”, Machine should display current software version. D. Press “DOWN ARROW” until display reads “CLEAR ALL” E. Press and hold “CODE/CLEAR” key. Display will read “CLEARING”, then “FINISHED” F. Proceed with down arrow and enter in proper time of day, configuration settings. G. Be sure to set all “MACH CON”, “PROD CON”, “TIME OF DAY”, and “PRICE” settings to desired selections. Link to comment Share on other sites More sharing options...
Vending 2019 Posted September 20, 2022 Author Share Posted September 20, 2022 I changed out the tray board and that was not the issue. Would these instructions be the same for the clear RAM if I have the upgraded UCB kit from Vendors Exchange? Link to comment Share on other sites More sharing options...
AZVendor Posted September 20, 2022 Share Posted September 20, 2022 No, the Ram Clear only applies to National boards. Link to comment Share on other sites More sharing options...
AngryChris Posted September 20, 2022 Share Posted September 20, 2022 If it stays in the same selections even after changing the shelf and the tray board and tray harness, then all that is left is the motor harness and the board. And my money would be on a pulled wire going from the motor harness to the tray board, although I have never dealt with such an issue personally.
