lemonhalf Posted May 12, 2022 Share Posted May 12, 2022 Hi all, I work for an arcade and our Dixie Narco 5591 drinks machine has been having some issues. We're unable to put it into test or setup modes, when we cycle it, it scrolls an * Followed by one 0. Keyboard beeps, but the display will never go into any modes. Back in November, we had the compressor serviced. Everything thing seemed ok but while it was booting up it got stuck on "Enjoy a ..." then since then it's been scrolling the */0 immediately when you plug it in. I pulled the board because the repair guy who has since disappeared thought it might be the board but not sure. We just reflowed solder on the connectors but no luck there. Any other suggestions on what to try? Link to comment Share on other sites More sharing options...
allen watson Posted May 13, 2022 Share Posted May 13, 2022 Try unplugging the door switch. It may be stuck Link to comment Share on other sites More sharing options...
lemonhalf Posted May 14, 2022 Author Share Posted May 14, 2022 No dice with the door switch. We also tried resetting it with the keypad unplugged, display, etc. Link to comment Share on other sites More sharing options...
AZVendor Posted May 15, 2022 Share Posted May 15, 2022 Pull the battery off the logic board and see if it powers up and works without the battery which removal will maybe reset the board. It kind of sounds like you somehow created some kind of a password. 1 Link to comment Share on other sites More sharing options...

It kind of sounds like you somehow created some kind of a password. We tried pulling the battery and the little jumper part it says to remove to get it to stop holding charge for 14 minutes, still nothing. We've also tried a new board and EPROM, still same issue. Also have measured voltages at the white box and everything measures ok there. Edited May 21, 2022 by lemonhalf Link to comment Share on other sites More sharing options...
lemonhalf Posted May 21, 2022 Author Share Posted May 21, 2022 Update, also will not accept dollars or change in current state. Keypad doesn't make beeps when you press it, should it? Link to comment Share on other sites More sharing options...

allen watson Posted May 21, 2022 Share Posted May 21, 2022 I had a 5591 that wouldn’t vend. I replaced the keypad, board, bill validator, coin mech, harnesses etc. etc. Come to find out, my evaporator was iced over and caused the machine to do weird stuff. I found this out because I took it into a shop and they diagnosed it. Strangest thing ever. it started with the keypad acting up, then the coin mech doing random things. I thought it was the disinfectant being sprayed on it during Covid. Link to comment Share on other sites More sharing options...
allen watson Posted May 21, 2022 Share Posted May 21, 2022 That was a couple years ago. I can’t remember if it was just the ice that caused it or if it was the probe for the thermostat that was defective Link to comment Share on other sites More sharing options...

But let me know if that's wrong. This is driving me nuts. Link to comment Share on other sites More sharing options...

He messaged me back and said it was the temp sensor shorted which caused all my issues. so I would unplug the temp sensor and see if that unlocked the board Link to comment Share on other sites More sharing options...

One behind display and one on the main board. Did you try both? Link to comment Share on other sites More sharing options...

I’m still leaning towards the door switch myself. You have to unplug the wires from the switch and make a little jumper wire between the two wires to simulate the door being open 1 Link to comment Share on other sites More sharing options...

I'm pretty sure it's not the door switch because we also get 3 beeps when I press it down and release with the door open so it seems like it's registering that ok. Right now neither of the mode buttons work. Could the mode button on the door go bad and lock out the one on the main board? I don't think the buttons on both main boards we got (old board and brand new board) could both happen to be bad. Link to comment Share on other sites More sharing options...
lemonhalf Posted May 24, 2022 Author Share Posted May 24, 2022 OK! Ryan from Snackattack got us sorted out on a quick call. Now my personal hero. We needed to unplug the temp control from the control board - it was locking everything else out. We're back up and going. Thanks for all the help trying to troubleshoot this also. 1 Link to comment Share on other sites More sharing options...
