Troubleshooting Danfoss refrigeration

Got a brand new CU-200 with my boat and does not seem to cool anything.
if i turn the thermostat, fan start, and it looks like something is running through the tubes, as far as i can tell. the condenser is not hot after one hour of running and i cannot feel the cold at all in the box.
The boat as not been use for a long time, how long do i have to run it to make sure it s working ? i touched the bronze tubes , i dont think there are any cold at all.
In doubt i will let it run all night, but i was expecting to feel something after one hour or so ... any idea to troubleshoot ?
Thanks in advance

The evaporator (the plate in the icebox) should feel cool after a few minutes. Sounds like you lost the refrigerant charge. If this unit is new it should be under warranty. Get it checked out.

who installed it? It could be a dozen things from electrical to refrigerant. many times the new lines aren't even connected because they just put the thing in for "show" to sell a boat.

The boat as been refit after a water entry and they did put a lot of things for "show". now i am playing puzzle to figure how to put everything together. After one night running, Compressor is a little hotter, warm in my hand, Fan still running, lines neither cold or warm, and still hearing the buzz in the box next to the plates. Touching the lines, i ve got the feeling something is going through, but it s subtle. I did not see any pressure gauge or window to check the refrigerant is there. Any way to do that without bringing someone on board ?

If your not hvac trained you may be better off finding someone that is. You may hear a gurgle or hiss if it's low on gas. But if it needs gas it has or had a leak. Also these units only need a few ounces of gas (134 in most newer units) refrig comps do and are supposed to be warm when running. very small units like this don't have gauges or sight glasses for the DIY person some don't even have a connection for the gauges. The buzz may just be relays buzzing.

CU 200 low refrigerant

Troubleshooting is very simple on that unit, normal failure of compressor not running reasons will be defined by number of red LED flashes on 200 Stainless steel panel. This is the same way automobile computers pinpoint troubles.

Compressor runs and there is no cooling means there is a refrigerant flow problem and nothing wrong electrically. The hissing sound indicated there is flow, no cooling now defines that refrigerant volume is low. Do not run compressor anymore until problem is corrected. Who ever installed unit is probably to blame for loss of refrigerant. When lines were connected and sealing disc was broken either line connectors were not positions correctly or permanent metal seal was not torque properly. Adler Barbour is aware of this common problem so someone should repair this under warranty
