Question about Koolatron (785169015699)
THE UNIT WILL NOT COME ON IT JUST CLICKS CONTENTIOUSLY , THE GREEN LIGHT BLICKS & THE FANS TWITCH.
The EC-23 machine. If it is making the clicking sound . Unplug it empty it. unscrew the 6 screws holding the back on. You will see a couple of circuit boards. You want to repair the upper right board. It has a 1000uf 13.4 volts Capacitior that has failed. You can unsolder it remembering where the negative side is and positive side. Replace it with a 1000uf and any voltage above what the cap says. Never go under the voltage specified. I put a 45v 1000uf. I found these at Radio shack. Put the new one in. Put it back together and your good to go. Most important is to put the new Cap exactly the same way keeping in mind negative and positive. I don't hope it will work. I know it will work!. lol Follow my direction and the machine will be like new.

Is there a way to check out the Coin input or an easy way to get out the tokens

I have one of these same machines and the problem sounds like a powersupply. A failed power supply doesn't have the voltage or current to run the electrical componants of the machine and all it will do is make a clicking noise. If the machine is left in this configeration for too long it will burn out the main processor board and you may as well toss it after that. The powersupply that came with the machine is located at the upper right side of the unit as seen from the back after the rear panel has been removed. This unit uses a standard 12 volt (Actual voltage is 13.8VDC) but at 75 watts. I haven't figured why these manufacturers like to rate their powersupplies in wattage instead of amperage. However, you can use Ohm's law is used where Voltage x Amps = Watts to figure the correct size of power supply you will need. Or to find the Amperage you simply take the watts (75), then divide it by the Voltage (13.8) then you will get an answer of 5.4 or to round it to the nearest 1/2 it would be 5.5 amps DC. I happened to have one of the Coleman Coolers that uses the same type of technology. So I was able to just rewire the power supply that came with it to be used for this machine. I found the Coleman PS more durable and I think it will certainly last longer as it is external where as the ps than came with the machine is internal and more subject to heat buildup within the cabinet. I was able to use the existing switch on the rear of the drink machine as the On/ Off and wired the Coleman PS Through it. Please be aware that the Coleman Plugs Directly in the 110V Receptacle and the output is at the Female Cigarette lighter plug. I Cut the Cigarette lighter plug off and soldered additional wire to connect to the ground and the Hot or + side I connected to the switch so the machine could be turned of and on. You will need a DC Volt meter to determine which of the conductors that are coming out of the PS is the ground and which is the + or the Hot wire. This a 3 position switch and after a different PS is installed it will become an On/Off switch only. If you need to purchase a power supply or sometimes better known as an AC adaptor be sure that it is large enough to do the Job. You will need a 12V DC PS rated at a minimum of 5.5 amps. I would get at least a 6 amp rated to be sure that it is large enough. I have seen them at prices from 35.00 to 125.00 so they aren't cheap!! The Coleman is rated at 5.25 amps and seems to doing just fine. It is priced at about 35 00 to 40.00
It is important to use a wire size that is compatable with the current or amperage that is used. Personally, I would used nothing smaller than a #14 when using it for the power feed wires on this type of Application. Also, I always solder the connection to ensure a tight connection. Loose connections are the dreaded No No for making electrical connections. A Loose connection can cause a buildup of resistance, Resistance causes heat, and heat can result in a fire hazard. Other ways to make tight electrical terminations or connections besides using solder are **** splices, splice caps and if used properly wire nuts. I hope this will shed a bit of light on this and may even help.

Bad power supply. Unit can be converted to run off of 12v DC
