J and T Vending Posted November 10, 2016 Share Posted November 10, 2016 My USI 3039 Snack Machine has one row of stuck / jammed buttons (Row C, 4, 6). As a temporary fix, I am able to push together on the keypad wiring connection and that will fix the problem temporarily until problem comes back which is usually by end of day. With this in mind, what are your thought for properly fixing this problem? Link to comment Share on other sites More sharing options...
AZVendor Posted November 10, 2016 Share Posted November 10, 2016 It's probably not stuck buttons but a bad keypad. If you need to replace it you can email me at rbepic4gatgmaildotcom. I would recommend replacing the buttons at the same time as they often get clouded from use and don't look great when the new keypad is put on.
