Dometic CF-110 compressor controls.

[Manateeman]

The compressor is a Danfoss BD35F. The controller is a Danfoss 101N0500.
There is a second box with a circuit board inside which I think is a SMPS converter. It’s connected to the controller and the display, the fan and the temp.
I can find the 101N0500 on line but not the other box.
Not sure how to test either.
The display shows no lights on AC. 120.
On 12 Vdc the fan runs and the compressor tries to start but the red error flashes . ..I think my dc wire was too small while I was testing ...
I’ve taken the two boxes out. Is there a way of testing them?
There is a slight bit of corrosion on the display cable prongs +5V and V test which are the furthest left labeled display in the mystery box.
On the circuit board inside the mystery box : RU 94v-0, BMX -01, E226252
7 wires go to the controller, 2 to the fan, 2 to the therm, 2 to AC IN, 2 out,
7 to the display.
All I want to do is to get the box running to sell it as we’ve already replaced it with a CF 80 which works fine for manatee crew frozen pizza.
Thank you in advance for replies.

Nobody has changed any of these compressor controls? I thought everybody down under had one in their truck or SUV.
Where are all the refrigeration wizards?
Squeak, squeak. Manatee for Please help.

We ask about salt shakers, we get a huge number of replies. Coffee makers...ditto. Surely somebody known Dometic boxes
Dometic CF 110. Same as the Waeco...yes?
What is the second black box attached to the display and the compressor control.
Where are the manatees going to put their ice cream ?
Help!

Have you checked the fuse at the power cord at plugs? U do have a lite and fan on 12v so that plug in should be ok.
I looked up the domestic manual, red light flash’s.nothing under-troubleshooting.
The waeco red light flashes “device is on but not ready for operation. Is the flash in a “grouped” way?

Hi. Thank you for the post. We have looked at a lot of older posts and videos on the web. We eliminated most of the classic issues. It’s the mystery box which is the problem and that is why we put up so much detail on it.
It ought to run on AC and we think the mystery box converts AC to DC. But it is also connected to the display. Got sidetracked on another project and am waiting for a reply from a company which sells the controller which attaches directly to the compressor.
Again, thank you. Very much.
The manatee crew.
