After a lightning strike the fridge does not cool.
A new controller has been installed. New coolant filled. The pump works, electrically all seems OK.
Somewhere the pressure disappears. No obvious leak.
I have a 400, built 2009, twin wheel type.
Very difficult to get to the system or replace.
I think the instalation is very similar on all types.

Anyone have an idea, or taken the hole fridge out before?
Any hint is welcome.
Thank you
Gordon

First read this post:

As you can see, the Isotherm unit is built into the pantry, and Hanse has used a lot of glue to assemble the furniture.
With the search function you can find a post where the evaporator  and compressor has been renewed. Changing the entire Isotherm unit is quite a job, since the pantry is assembled around the unit.

you can find instructions to read out the error codes from the compressor. Just mount two cables with a bulb on the compressor. Then start the system and watch the bulb. No blinks = OK. One or more blinks = Fault.

As you can see in the first link, I have made an inspection hole in the plywood to the left of the oven. You may be able to work on the compressor with the aid of a mirror, but my solution is less frustrating.
If  you search fridge/isotherm/cooling e.g you will find hundreds of hits.

(You can find advices like this: " I put a LED through the wood so I could check the fault-codes.
It is connected to the little "+" and "D" beside the compressor.
There are multiple pages on the net with explanation of error- finding the Danfoss DB35.)
