Far be it for me to say I am an expert, vend1ng...... oh wait I did indicate in my second post that I wasn't a refer tech. So pardon me vend1ng for "stunning" you so, I didnt realize you were so thinned skin and intollerant. Lets look at InspectAPedia @http://inspectapedia...ACCoilFrost.htm. Scroll down to item #9 under "What Are the Common Causes & Repairs for Ice or Frost Build-up on an Air Conditioning Cooling Coil" . Icying does start at the top and if caught early enoughthat is where it stops because it is taken care of then. My company has over 3000 machines in the field. This includes office coffee, snacks, cold food, drink machines, both box and glass fronts, coffee vend machines. Our drivers are good, but they fill machines and go to the next one and alot don't look under the chute. This allows the ice to build up over some time, eventually covering the evaporator. We have taken these units out and check freon levels and they have been low, we check for leaks and sometimes don't find the really small ones, we recharge and put back in the field and they are fine for a short time. Then they start to freeze up again. Check freon levels and yes they are low again. We finally find the leak and repair it, and what do you know, no more freeze ups. But of course that is only in my world. In Mr. Vend1ng's myopic world it doesn't work like that. As to the statement "On most compressors now days they don't have enough BTUs to freeze cans " another tale from the impossible : We had a National 431 cold food, less than 6 months old had a triac go bad, I know Vend1ng triacs never go bad in your world, but this one did. Driver checked the temp in the machine, it was down to -5 deg. Machine had frozen rock solid everything. I didn't think it could have done it when the driver called me, so I went to the machine and it was down to -8 when I arrived. Called National and they said it wasn't possible, Not enough BTUs to do it. Had to put my temp probe in machine and take a picture of the readout to send to Crane National. I guess Vend1ng was Mr. "I know everything" at National that day too. Never claimed to know everything, admit that I am not an expert, only relaying what I have seen in my work over the years. Hate seeing good site trolled by self important arrogant people. So please Vend1ng, please stayed "STUNNED" when someone says something that may go against what you believe. At one time people thought the earth was flat, and they too were "STUNNED" when sailors sailed around the earth. You make the shallow minded people of the world proud sir.

Here is another idiot that doesnt know what he is talking about: watch at about 1 min 55 sec. :. Don't you just wish God would strike these morons down so Vend1ng doesn't have to breath the same air..... Vend1ng..... Oh my God someone call 911 Vend1ng has gone into "OVERSTUNNED".

Steve, by no stretch of the imagination am I an expert on Dixie models, but are you sure your machine is a 501E. In my 22 years in the biz, Coke and Pepsi have supplied all of our units and all of the 501E units we have, have been 9 columns. It maybe that this style is the ones coke and pepsi use, but Dixie may also sell a 10 column 501E, but I have never seen one. Now that I think about it ours are "501E-9". I guess that there maybe a "501E-10" Either way if your is a 10 column, I have been thinking about this and I remember we had one doing just this thing and I found a broken wire in the harness. It was located near the bottom hinge. There are harness connections near the bottom hinge that contain connections for motors, switches ect... If one of the wires for the cam switches is broken or popped out of the molex connector then this could cause your problem. Hope this helps.

I believe your correct Steve about the freon. Everytime we have an evaporator iceing up at the top, when we tap the line and check the freon level, it is low. I am not a refer guy, but over the past 22 years this is what I have seen over and over. Yes Ruskie, this can be the case with a manual cold control. I hope you find the problem with your unit. I know frozen systems can sometimes be a bear to figure out.

This depends on the machine. If this is a snack, then most, if not all, snacks can have this feature turned off. If it is off then it is possible that the sales meters are correct. If this is a Royal 660 GIII, then you will be off. If vending bottles, one column tied to one button then the machine will vend one time, stop and listen thenvend again one time and stop vending that selection until the door is opened and closed again. You will be off two bottles because it didnt hear either one. If you have two columns tied to the button it will vend two times out of each before putting that selection "Sold out". Your count will be four short.

This depends, as always you should not store items under the drop chute which will block the circulation around the evaporator. Given that, low freon could be a problem. If this is the case usually the evaporator will ice up from the top and in the beginning can ice the entire thing up. After awhile the freon will be so low the icing will only be at the top. Air leak around the door gasket, esp. if you live in hummid climate. Warm, moist air condensates on evap. and will freeze and build up over time. Just had a Vendo freezing up and one of my men found the drain spout leading to the drain pan was broken off. The holewas large enough that the warm air was being sucked right in. If you have a manual cold control this could be set too low or might be faulty. Are you sure the evap fans are working or are you going on sound. If you didn't see the blades running, the blades could be broken off and you could be hearing a bladeless fan motor. This will for sure freeze up.
