I experienced the same problem as you last year, the power unit burned out and the whole unit had to be replaced at a substacial cost! Believe it was around €850 + postage.
The CLD company are now taken over by German company Wabesto but still produces the units in French site. I tried to contact an expat Irishman Lee Hawkins at the factory in France
just a few weeks ago but he has not responded to my emails, so have maybe left. It was very handy to have someone who speeks and understand English
but hopefully I do not have to contact them again.
Must say I'm not totally happy with the system from CLD, but this can be due to the fact that the lid on the freezer
don't seal properly and air gets in and therby frosting the evaporator. Also the centrifugal cooling water
pump don't get sufficient suction head
pressure since I have a cat that does not submerge enough.
If I get another breakdown I'll replace the entire system with separate freezer
and fridge evaporators.
Ishould provide you with the email
address to Lee, but Ihave that on another laptop
so I'll post it to you later.
Happy lead free sailin!
