I have a similar machine that I put 134 in about 5 years ago and it’s still cooling great. My AC buddy says the Oils aren’t compatible. We tried it in another one and that didn’t work. It only cooled for about a week.

So it’s kinda tricky. The electronic board AND the original price board are linked together. Originally, the price board set the prices. The fist switch being 5 cents and the next being 10 cents and so on. When slid to the left they are off. To the right they are on. Now that a Lutech board was added you have to price both the Lutech board and the original price board. However, the Lutech board now sets the amount while the original price board no longer recognizes the 5, 10, 20, 40, 80 cent settings. The original price board is now kind of a location for the price set on the new board. If you go to the new board and enter .50 on the A column, whatever the A column is set in the original board will be the new price. Even if the old board is set to .25, it will be .50. So now all the locations that are set to .25 on the original board are now .50. I have about 10 machines with this setup. Once your machine starts jackpotting the coins the board is toast and it is no longer manufactured or repairable. Those old APs are at “end of life”.

You have to also set the price board. That’s the board with all the dip switches above.

I’ve changed out a lot of mine with the led bulbs that are compatible with ballasts. D&S has them for machines with starters. You just remove the starter and put the bulb in. Some are even directional. Love the D&S stuff but hate their shipping charges The led bulbs at the home centers do not work with machines that use a starter. My friend Mark just sent me his 24” led kit that is really cool. Super light weight and can be mounted with 2 sided tape or an included mounting kit. He recomends bypassing the ballast and wiring them directly to 110v. They can be linked together to light up a soda machine.

I just bought a whole new port assembly for mine.

How much volume do you have to do to qualify?

It was at a new location and the management looked concerned. I couldn’t narrow down the exact problem so I swapped it out with one in storage. It has worked great for the last 3 years. 🤷‍♂️🤷‍♂️

Check your prices. Those are notorious for loosing the prices. Then make sure your coin tubes are full. I had one doing something similar and had to replace the board. Actually I replace the entire pull-out.

Could be the micro switch on top of the elavator or at the base of the picker cup. Check out the manual and follow the trouble shooting guide on x/y homing error. Don’t forget to pull the door switch out when testing the homing switches. https://des.az.gov/sites/default/files/media/bevmax_4_5800_operators_manual.pdf

Yes I have. You need to disable your card reader right away. Then order a new EPROM.

I have several Vendo drink machines that will not report the cash sales nd there is no fix for it.

When setting two deep you need the tall black clip. When setting 3 deep cans you need two white shorter clips. If you test vend the product while looking up underneath you’ll see the reason for the gauge bar locations and the plastic clips.

That’s for the two deep 16oz monsters and 16.9 oz bottles. I haven’t had any issues with the gauge bar on 3 deep cans other than having the wrong plastic clips.

The Univendor has some quirks. You may have to advance the column by holding the motor switch open and pressing the door switch. Also, I have 2 Univendors that are out of alignment regarding the bottom gauge bar. The normal position of the 3 is the center for cans. However, if the back can isn’t dropping correctly you may have to put the bar at an angle with the rear of the bar being on the largest setting and the front being on the middle setting. There are also specific plastic clips that need to be in placed on the gauge bar.
