Hey all, I have bought out an account and the old machine at the account.
It's a Vendo V264-148 with a Mars TRC-6800H (model 708-08442) coin handler with a Mars bill changer that I sent out to get refurbished.

A few issues that the machine had or still has:
1. The cooling system ices up and the fan starts tapping against it making a noise. Sodas are cold all the time even with ice.
2. I would like to raise the price to .75 per can but cant figure out how.
3. The lights do not work after replacing the flourescent bulbs behind the Coke front plastic panel.

I probably can replace the ballast and fixture to make the lights work.
I probably can figure out how to raise the price.
The refridgeration system on the other hand is a show stopper for me. I dont know how to work on these units nor do i plan to. I could buy a whole new unit for 299.00 and replace it but what do you guys think? Any quick fix for a machine that is icing up?

Try lowering your thermostat just a tad, see if that helps.

Sounds like a good idea. Can you tell me where the thermostat is located and how to adjust it? I imagine its just a screw driver adjustment right?

I don't know where the thermostat is on yor machine. Your manual should spell that out. You should get one. They are most helpful. Frequently it is menu driven rather than a knob.

As for my experience with icing... It sounds like your compressor is just running too long. I would first try pre-cooling your drinks if you can. Bringing 500 80 degree cans down to 35 degrees or whatever would be quite a work out for any refrigerator.

Also check the door seals to make sure that none of the cold goodness is leaking out of the refrigeration compartment. If the seal is bad or missing, the compressor may have to work too hard.

1. The #1 reason for icing is an air leak. It is pulling in moisture laden air which freezes.
a. DEFROST MACHINE COMPLETELY. Using rags, get as much remaining water out.
b. Open the door and insulator door. Spray WD40 on the insulator door gasket that touches the main body when closed. SLOWLY close both doors. Lock door. Open doors. Look for dry spot(s) on main body. This will show you if/where there is an air leak.
c. Check to make sure the can shute door is selling and not warped.
d. Check to make sure there is no open areas in the area where the reefer tubes come into the cold compartment from the reefer deck. all must be sealed.
e. make sure your condesation tube is looped and unblocked inside. make sure any condensation in the cold compartment gets to the tube drain area of the cold compartment floor.

2. Price changing. The Mars 6800H is easy to set.
a. unplug changer from machine
b. there are two "banks" of toggle switches on the inside of the mech. One bank is for options, the other for pricing. look at the pricing bank of switches .
Going left to right the toggles are: $5c, 10c, 20c, 40c, 80c, ...... ON IS UP
c. .75c = switches 1,2,3 & 4 UP, all others down.
d. plug the mech back into the machine. If you do not do #a. changes will not take effect.

3. Lights, Unless this is for home use and you want the "gee - neato" affect of the lights, don't run them. Locations usually want to save money. It is a good selling point to get locations to tell them you don't run lights to save money.
a. the light ballasts go out on these. They can be purchased at a good electrics store. Match the ballast exactly .

I hope this helps,

Thank you very much. I will go try these suggestions out and figure out where the problem is.

Ok I had a new thermostat installed (and now I know where and how to do it, it was easy).
The cans are now MUCH colder. As in make your fingers ache if you hold the can in one position to long lol.
I defrosted and wiped out as much moisture as I could. Before the thermostat install the defrost lasted 3 days. After the thermostat install it ran 5 days with no ice build up.

I will next try out the seal test using wd-40 as described.

Thanks again for your helpfull suggestions. I appreciate it.

And if you are wanting to light the lights, before replacing the ballast, try the starter. Another common source and cheap fix before going to the ballast.

Compressors on vending machines or very similar to any other refrigeration unit. Therefore, any shop that repairs AC's, Refrigerators, Freezers etc should be able to repair your unit when needed.

I use to send my compressors out to be refurbished when they went bad at the cost of $225 each. I now send them to a local refrigeration shop to get repaired for about $60.
The specs for the compressor are generally located on the actual unit or on the Left side door outside of the machine.
Good luck.
