Fermo Vending Posted January 11, 2023 Share Posted January 11, 2023 I have a Bevmax 5591 that isn't cooling. Evaporator & condenser fan are running. Compressor feels hot. Fans aren't frozen. Is my compressor shot? If anyone has a reliable tech, I'm based out of Hudson county NJ. Link to comment Share on other sites More sharing options...
Vendo Mike Posted January 11, 2023 Share Posted January 11, 2023 Blistering hot or warm? Compresser should be pretty warm but not scolding. Is the evap coil getting cold? What temp is the cabinet holding? Link to comment Share on other sites More sharing options...
Fermo Vending Posted January 11, 2023 Author Share Posted January 11, 2023 Pretty warm, not hot. I was able to touch the compressor without being in pain if that's a measure of anything. Nothing is getting cold, the temp of the cabinet is holding at 64 degrees. Link to comment Share on other sites More sharing options...
cvending Posted January 11, 2023 Share Posted January 11, 2023 If it is running and both fans are running, my guess would be you are low on freon. Trying ti find a vending tech casn be a challenge, Thosde are not the easiest units to work on. If you can't find one, try a local bottler to see if any of their techs moonlight. Just a shot in the dark. Link to comment Share on other sites More sharing options...
Fermo Vending Posted January 11, 2023 Author Share Posted January 11, 2023 I thought I could be low on freon as well, but I don't have the equipment to test. I purchased the fully refurbished machine in June of last year, so if it's already low on freon it's likely I have a leak, right? Link to comment Share on other sites More sharing options...
AZVendor Posted January 11, 2023 Share Posted January 11, 2023 (edited) If the compressor is cool or only warm from the fans running then your thermostat might be bad or a wire is burned on the side of the compressor. If it's truly hot and it's running (which it should be since the condenser fans are on) then look at the evaporator in the right rear of the cabinet and see if it's solid white and frozen. If it is then turn it off and let it defrost while you look for an air leak. Check the shelf harnesses where they enter the cabinet, the gasket around the delivery bin (called the recovery unit), and the gasket on the glass door. When you restart it then watch it over a few days to see if it begins to ice up again which is again, an air leak or low freon.

Fermo Vending Posted January 11, 2023 Author Share Posted January 11, 2023 The evaporator is not frozen and I'm fairly certain both fans are on. What's the best way to test the thermostat & an air leak? My old man owned an HVAC company and used to have a solution he'd spray on pipes to help him detect any leaks- something like that? I'm trying to avoid paying for a new compressor ($1,000) or even a refurbished one ($400) and then running into the same issue. Link to comment Share on other sites More sharing options...
allen watson Posted January 11, 2023 Share Posted January 11, 2023 (edited) I’ve had issues with my 5591’s icing the evaporator. It’s hard to see the ice without pulling the lower shelf but you can see it. Sometimes it’s a thin layer in the backside. I would unplug the compressor and wait a couple hours. If it has any ice it will accumulate in the pan below the compressor. You can pull the delivery bin out and check for water accumulation.

Fermo Vending Posted January 11, 2023 Author Share Posted January 11, 2023 Ok I'll check that out. Is the compressor unplugged from the backside of the machine, or do I need to remove the bottom tray for that as well? Link to comment Share on other sites More sharing options...

You can unplug it from inside the access door and still leave the rest of the machine running. The plug is below the control board at the power supply Link to comment Share on other sites More sharing options...
AZVendor Posted January 11, 2023 Share Posted January 11, 2023 What your Dad did was spray soapy water on fittings to see if it bubbled. Most leaks don't occur at sweated fittings like these units have. Also, you won't get a refurbished compressor for $400. This runs a 1/2HP compressor that is more expensive than that. We used to rebuild them for $800 but that price is up towards $1000 now. A new unit for $1000 is better, IF you need a compressor, which you probably don't.

What makes you believe it's not the compressor? I trust your experience more than the guy on the phone that said "it must be the compressor".

Fermo Vending Posted January 11, 2023 Author Share Posted January 11, 2023 Well, to be fair to the guy he did sell it to me- I got it from D&S Vending, and he's offering me a replacement (refurbished) for 400$, or a new one for 1,000 with a one year warranty. I don't think he's trying to get over on me, but he's based out of Cleveland and can't actually look at the machine Link to comment Share on other sites More sharing options...
AZVendor Posted January 11, 2023 Share Posted January 11, 2023 D&S are good guys but like you said, they can't properly diagnose it over the phone. The refurbished unit is probably a good, used unit that they might guarantee for 30 days. When did you buy the machine from D&S and what was the warranty on it?

Fermo Vending Posted January 11, 2023 Author Share Posted January 11, 2023 I bought it in June and the warranty was for 30 days unfortunately. Link to comment Share on other sites More sharing options...
allen watson Posted January 11, 2023 Share Posted January 11, 2023 As a refrigeration tech there’s no way I could determine the exact cause of a warm system without knowing the system pressures, if any. Not to mention a list of other checks. My experience has been frozen evaporators due to air leaks, condenser fans failing and dirty condensers as the three top reasons for a warm cabinet. However, that’s just based on previous repairs and doesn’t mean that any of those are your problem. as far as compressors failing that is also a possibility but just a guess. Compressors rarely die they are usually killed. Mostly by liquid coolant entering thru the suction line. You really need to have a qualified refrigeration tech take a look at it. You can find them under HVAC and HVACR repair. Link to comment Share on other sites More sharing options...
AZVendor Posted January 11, 2023 Share Posted January 11, 2023 It sounds like the compressor is still running but if it clicks on and off then it should be replaced. Otherwise it should only need to be recharged by a qualified tech. Link to comment Share on other sites More sharing options...

I let the machine run over the weekend and I double checked the coils, it turns out one of them had some ice build up. It was a small section of the coil, but now i'm leaning more towards that the unit needs freon and the compressor might be good. I'm waiting to hear back from a tech that should be able to put freon in it. Do you have any other thoughts? Thanks a lot for your help Link to comment Share on other sites More sharing options...
AZVendor Posted January 16, 2023 Share Posted January 16, 2023 Yes, it's low on freon then. Link to comment Share on other sites More sharing options...
