AZVendor Posted September 26, 2013 Share Posted September 26, 2013 What symptoms are you getting from the cooling unit that leads you to think it needs to be replaced? Does it click on and off without starting? Does the compressor and both fans run but not cool the machine? Link to comment Share on other sites More sharing options...
Walta Posted September 26, 2013 Share Posted September 26, 2013 OK let’s play Carnac. The English seems good so let’s say North America. Only 2 A’s in the post so let’s say not Canadian. The tone has a Midwest feel but I am now on thin ice. Really where on earth are you? You need a better diagnosis than needs a unit. Are both the inside and the outside fans running? On this model often the refer unit is controlled by the computer and the unit will not start running until the computer see the door closed for a full 5 minutes.

chris in bc Posted September 26, 2013 Share Posted September 26, 2013 I wonder if the white id tag on the left side of the vendor has part of the model number scratched off? I know Royal makes a 650, the writer has stated a 350-10........10 selections would make it a modern machine. 1) dragstarchad-can you take some pictures? Are you able to read the white tag on the left side of the vendor? 2) you can call royal vendors at 1 800 321 8637 Link to comment Share on other sites More sharing options...
AZVendor Posted September 26, 2013 Share Posted September 26, 2013 If your machine is not a Merlin 2000, then Walta is correct that your compressor probably won't even start until the door is closed, or the door switch plunger us pulled out, for about 5 minutes. Since you have 10 selections, that also rules out a Merlin 2000 but you could have a Merlin III or possibly even a GIII. Your model of RVMCE is for Magnum Circular Electronic which is a proprietary door for Pepsi. I'm not aware of any GIII machines built for Pepsi, so I'm leaning toward you having a Merlin III. Further information and especially a photo inside and out will be very helpful. Link to comment Share on other sites More sharing options...

I can install the cooling unit my self. how much are they and where can I get one? or do I try to sell it as is Get a extension cord and unplug cooling unit... Plug it in and see if compressor works....... let it run several minutes and see if evaporator frosts over. If it does then compressor is good. Plug it back in and wait about five minutes. Go smoke a cigarette drink a cup of coffee and come back. Don't open door just feel in back of machine to see if you can feel the air coming out from the condenser fan motor. If not open door and see if there is a sheet with a flow chart on the inner door. There should be a test that you can perform on the refrigeration relay. If so do test to see if compressor runs. If it won't come on replace relay. The S/N is similar to D/N's the AE at the end indicates the quarter and year the machine was made. I don't know Royals sequence. A most likely means first quarter and the E is the year. It tells me the machine is old. Since it is a 10 select and a 350 it most likely is a double depth can vendor with a merlin 1 board. If I am correct it has a manual cold control not electronic. If I am correct RUN fast and don't look back.Many reason why and I won't go into detail. Compressor replaced here will cost you $325.00........ But if this is what I think it is.... It will get you about $30 to $40 going across the scales..

dragstarchad Posted September 27, 2013 Author Share Posted September 27, 2013 I didn't have time to call royal today. but I just looked at the tag on the left hand side of unit and the m# is RV MCE 350-10 PE 2756 S#0053-1157AE I had a guy come look at it and said the comp was bad. its running but not pumping. I guess I would like to no if its worth putting a cooling unit in or not? don't no the year of unit but it is very clean with 10 diff buttons on the front and u can change the price per button.

AZVendor Posted September 27, 2013 Share Posted September 27, 2013 There is no need to call Royal about this problem as there isn't anything they can tell you to do except to find a repairman. Did your guy put a line tap and gauges on the compressor? If so what was the low side reading? Did he attempt to recharge it and did it respond to adding freon? Unless he did all of this there is no way to determine it is "bad." If he tapped a sealed system and found the low side was way too high, then you have leaking valves in the compressor. If the system was already tapped and he found the low side too high, and extracted some gas to bring the low side down to specs, did the low side rise again to a high reading? If so, you have bad valves. If he added gas and the low side refused to rise up to specs after several shots of gas, you either have a large leak or bad valves. As you can see, just looking at it and listening to it, no proper diagnosis can be made. The proper low side pressure in a correctly charged and correctly operating system should be between 18 - 20 lbs. If this low side pressure can be maintained and you have a frost line at the transition of gas into the evaporator (left top corner on a Royal) the unit should cool fine. This machine is definitely worth repairing, depending on how much you want to spend. The worst case is a rebuilt cooling system with a new compressor for around $325-350. However, you could be looking at a much lower cost if you are simply low on freon or if it has a leak. Link to comment Share on other sites More sharing options...

I had one just like it, came out of storage units I bought for cheap, it looked good but sold it for $500. This was my first Royal. Link to comment Share on other sites More sharing options...
