Chkoolaid1 Posted September 13, 2016 Share Posted September 13, 2016 I'm having one of those weeks that I heard can happen but have never experienced. The one where everything seems to go wrong, so here's hopefully my last question for a while. I've got a vendo 480D, and I can't get power to the door. I've unplugged and plugged back in the machine. Flipped the toggle switch. Loaded up the coin mech (thinking it was the coin mech which I asked about Friday) and I'm not sure what to do here. Any one have any ideas? I'm thinking it could it be the control board but I'm not sure how to tell if that's it. The compressor works great and it keeps everything as cold as a new machine. This is an older machine that I just put on location. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
lacanteen Posted September 13, 2016 Share Posted September 13, 2016 I could be wrong, but I think there is a fuse on the panel in the lower left in the cabinet. We've replaced a few transformers too. You're going to need a volt meter to test that. Link to comment Share on other sites More sharing options...
savend Posted September 13, 2016 Share Posted September 13, 2016 I agree with lacanteen. The other thing that I would look at is the control board behind where is says caution in the picture. Some times the connectors can be pulled out or a pin bent over. Link to comment Share on other sites More sharing options...
AZVendor Posted September 13, 2016 Share Posted September 13, 2016 If the fuse is good (ohm it out) and there's no voltage from the panel where the fuse is to anything in the door then you probably have a bad transformer. Email me at rbepic4gatgmaildotcom if you need a transformer. Link to comment Share on other sites More sharing options...
Chkoolaid1 Posted September 14, 2016 Author Share Posted September 14, 2016 Is the fuse similar to car vehicle fuses in the sense that I can pull it out to tell if it's bad? This is going farther than I've gone before with these machines so I hope this question isn't too funny, but how do I test the transformer using a volt meter? I checked most connections and besides being dirty it looked like they were all in. I wasn't looking for bent pins I'll have to check when I'm there tomorrow or Thursday.

savend Posted September 14, 2016 Share Posted September 14, 2016 Fuses should be a quarter turn & they should come out so you can look at them. I've seen breakers too so check that. Should be the same place as the fuses. Link to comment Share on other sites More sharing options...
AZVendor Posted September 14, 2016 Share Posted September 14, 2016 Follow the wiring diagram on your machine inner door and/or on the electrical panel itself. There is 110v in to the transformer and 24vac out of it. If you don't have 24v out then the transformer may be bad but you first have to ensure you have 110v in to it. There's always the chance that the 110v side has come unplugged. Link to comment Share on other sites More sharing options...
allen watson Posted September 16, 2016 Share Posted September 16, 2016 Are there drinks in it?Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
AngryChris Posted September 16, 2016 Share Posted September 16, 2016 Make sure no wires came out at the bottom of the cabinet next to the refrigeration deck. I've had royals do that. Unfortunately, you won't notice until you get down and inspect the wires. Just don't shock yourself lol. Link to comment Share on other sites More sharing options...
Chkoolaid1 Posted September 18, 2016 Author Share Posted September 18, 2016 There are drinks in each column and coins in the mech. I'll be there tomorrow afternoon and will be able to check all of these. Main goal: identify problem. Secondary goal: don't get shocked. HahaThanks guys!Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
allen watson Posted September 18, 2016 Share Posted September 18, 2016 Is that a single price machine? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
CajunCandy Posted September 19, 2016 Share Posted September 19, 2016 It's a muti-price machine allen. Link to comment Share on other sites More sharing options...
allen watson Posted September 19, 2016 Share Posted September 19, 2016 I have a 480d that I opened a while back and the door was dead. I followed the main harness from the door thru a panel by the Refrigertion unit and found that the harness had been jerked loose from the transformer. The zip tie that secured the harness to the door broke causing excessive slack which caught on the door the week before and pulled the wires from the transformer. Just trying to cheer you up.

Chkoolaid1 Posted September 19, 2016 Author Share Posted September 19, 2016 The harness it may be! I'm getting a current through some of the wires to the control board.Pic below. I'm wondering if this is problem. The top wire is live. The lower one, which I'm touching, is dead.Pic below. Of the 3 here, the one I'm touching is dead, the big one that goes up to the motors is dead. And the 3rd is the live one in the previous picture. Pic below. Followed through to the door, only one is live. Idk if this was an outdoor machine but the wires are really dirty. Could that be the issue?Pic below. The purple ones are always dead. When I flip the toggle some of these come alive. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
AZVendor Posted September 20, 2016 Share Posted September 20, 2016 Pic 1 is wiring to your cold control where only one is live and since the machine is cold all is good. Pic 2 is another two conductor wire to the evap fans which are good. There will be no current in the motor harness unless the logic board is sending current there. Don't worry about the filthy wires in the bottom of the door yet. If any wires in the area of the logic board come live when the toggle switch is turned on then you have transformer power to the board. The power in to the board is the top right connector with red/black being 110vac and the two yellows being 24vac. It sounds like you have a bad logic board. If you need one you can email me at rbepic4gatgmaildotcom for an exchange board. By the way, if you really want to know what's going on invest in a voltmeter and become familiar with it's use.

Chkoolaid1 Posted September 20, 2016 Author Share Posted September 20, 2016 Dang, is there a cheap way to get a board repaired? Or is replaced the best option? Email sent. I wanted to get a real voltage meter, but my budget is tight for the next few weeks so I settled for the cheap option. Do you have one you recommend? Thanks for the help everyone! I don't know what I'd do without this forum. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
orsd Posted September 20, 2016 Share Posted September 20, 2016 This will get you by... https://www.sparkfun.com/products/12966 I have never used that model myself but sparkfun is a good source for electronics. And for 15 bucks if it saves just one service call it has paid for itself already. (Use an Extech myself, looking to get a Fluke) Link to comment Share on other sites More sharing options...
Chkoolaid1 Posted October 17, 2016 Author Share Posted October 17, 2016 Turned out to be a fuse! I can gladly say I did not get shocked, however as I was following the power from the outlet through the machine I did stick my hand in the fan lol. Thank you again guys for all the help!Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Snickers Posted October 18, 2016 Share Posted October 18, 2016 I'm curious. Can that machine be switched over to MDB ? Link to comment Share on other sites More sharing options...
AZVendor Posted October 18, 2016 Share Posted October 18, 2016 It can but it will never report cash sales correctly if you put a card reader on it. Link to comment Share on other sites More sharing options...
Chkoolaid1 Posted October 18, 2016 Author Share Posted October 18, 2016 Is there a rule of thumb when matching a validator to this machine? Or any non-MDB machine for that matter. I got an email saying it's not taking bills. I was looking around for a cheap one in case that's what it is. It's not a high volume account, so I'm not looking for a new/top notch one. Does it have to be the same one or just match the pin count/layout and Volts? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
lacanteen Posted October 18, 2016 Share Posted October 18, 2016 The key with non-MDB is voltage and harnessing. What is in there now? For a donation to this forum, I'll send you non-MDB payment system. If anything pics of the plugs will help. Link to comment Share on other sites More sharing options...
