Sboxllc Posted March 31 Share Posted March 31 I own an AP Snackshop 5000 and it worked great until we moved it to its current location. We turned on the machine and a couple of semi-conductors on the bottom right of the control board blew. I thought it was the old wobbly fluorescent light grounding out so I installed a LED light, and purchased a replacement control board. After plugging in the new control board, it blew again in the same place. Does anyone have a wiring diagram of this control board or know what part is surging power through my unit? (Note: I checked continuity on the power cable and it isn’t shorting out.) Link to comment Share on other sites More sharing options...
AZVendor Posted March 31 Share Posted March 31 You're not protecting the board from grounding out. The tail end of the board is supported by one hole into a standoff. It's probably shorting out there. Link to comment Share on other sites More sharing options...
Sboxllc Posted March 31 Author Share Posted March 31 I thought about that as well. So I ensured that all holes were mounted to the frame. The picture is the circuit that keeps blowing. Link to comment Share on other sites More sharing options...
Sboxllc Posted March 31 Author Share Posted March 31 Do you know where these wires lead to? Thank you for your time in helping me out. Link to comment Share on other sites More sharing options...
AZVendor Posted March 31 Share Posted March 31 The black wires are power in, and you're missing the rubber grommet that should protect the board at that hole. You're probably grounding the 110v. Link to comment Share on other sites More sharing options...
lacanteen Posted April 1 Share Posted April 1 Check the coin mech. There's likely a dime fell through the space above the dispenser and is shorted to the board in the mech. If you laid the machine down when moving it I am certain this is what happened 1 Link to comment Share on other sites More sharing options...
Vendo Mike Posted April 1 Share Posted April 1 Looks like the bridge circuit and likely the varister have shorted. The diodes that the 2 blown traces lead to are probably shorted out. The 4 diodes in that bridge circuit and the varister will need to be tested and likely replaced. To LACanteen's point, I'm pretty sure that's the supply for the 110V Micro Mech which likely shorted as well. 1 Link to comment Share on other sites More sharing options...
Sboxllc Posted April 2 Author Share Posted April 2 Thank you guys so much for the help. I know now how to rework the board and get the machine back up and running. Change definitely got in the coin mechanism and grounded out. I guess the beautiful state of Wisconsin had it out for me. Link to comment Share on other sites More sharing options...
tblake05 Posted April 2 Share Posted April 2 Check and make sure that quarter isn’t the type with the extra leaf on the stock…. Doesn’t look like it but it’s tough to see. If it is, it’s worth some $$$, prob enough to pay for your two burnt up control boards. Link to comment Share on other sites More sharing options...
