FWIW the EU Design database has a record of EU Design # "634092-001":

oami.europa.eu/RCDOnline/RequestManager

Unfortunately the information isn't very useful.

Update - I've finally removed the board or I should say exposed it to view. I cannot see anything that say to me that "I am broke"
The fuse checks OK. So I'd welcome any further advice from people with more experience than I.  I do have a bro-in-law who is a ret'd tech to fall back on when he visits next.

The pics should show both sides of the board.

 

Thanks and Regards

 

Denis

Juergen - Nah, optical illusion - it's pretty well flat on top. See 4th pic. The entire board is coated with a shiny thin clear epoxy substance and there are no breaks in it anywhere around the capacitor.
Thanks

Denis

With the 240V disconnected & the 12V dc power to the unit, there should be 12V DC on the 2 pins where the biro is pointing?? The fuse on the board is for 240V AC only. As you have said the unit runs ok on 240V, then the capacitors are ok.

When powered with 12V try removing leads C & T & fit a shorting link as in picture. The compressor should run.

Thanks Daryl, I'll do that in the morning as I need to reconnect everything...not a lot of free space in there. Will report back.

EDIT.......... tried it and no go. Also tried straight to the terminals.

Probably getting past repair, as I suspect the unit is faulty in the change over switching from the 240V to 12V in the unit. Will post the Danfoss instruction sheet & a pic of the switching FETs & Diodes.

Thanks Daryl, getting way past my limits so I've printed off the sheet and pics and will pass onto Bro-in-law who does not believe in throwing away stuff that cannot be fixed. We'll see him in the next few days as he wants to show off his new 2nd hand camper.
Worst comes to worst I can run it off an inverter.
So many thanks for the help you've given - it is much appreciated. Will post back eventual outcome.
Regards

Denis
