I have a chap who can gas the compressor with ease , I just can't get access to the bloody thing !
Everything seems to be working fine with my control unit and compressor , I think a recharge of the R134a would help a lot , you would think hanse would have Fitted and wired the unit to the battery bank with appropriate cabling ? As not to drop voltage ?

This weekend I had another problem. 
On Friday the fridge was quite full. It was running all night. Seems it never stopped and I was worried. In the morning everything was very cold. Stuff in the freezer was very frozen.
Is there a regulator somewhere? Can not find any.

I got the feeling that when the freezer was full, it ran much longer and got too cold.

Yes there is a regulator, you find it if you look from the topside into it. As far as i remember it is under the freezer. You may need a mirror to find it. or use your mobilephonecamera.

OK, Thanks. 
It might be that it was covered by something and got false temperature.

In my 400 - the regulator is placed INSIDE the freezer compartment

We have the same blue liquid pooling in our Hanse 415 isotherm fridge.  Any idea what this is and how it affects cooling performance?

Search "Isotherm ASU", I suppose that the blue fluid is the cooling agent from inside the container.

ASU may be explained here on myhanse in "advanced search", else google it. As I remember AutomaticStartUp is a system where the compressor is working overtime when there are plenty of amperes, (then freezing the container), and  when the voltage is low, the compressor rests while the frozen container delivers the needed cooling.

Hi 

Has anybody tried to replace the compressor including the evaporator in a 370 or 400?

My compressor can no longer cool the fridge down even though its running instant. I had a coolant service guy to look at it and top up the coolant, but it didn’t help. Voltage is also fine. The service guy suggestion is to replace both compressor and evaporator.

I can see in this thread that Idelfix seems to have been able to take out the compressor through the small locker next to the oven. Can anybody confirm that this is possible?

If the compressor can go out through the locker, I believe that replacing both parts should not be that complicated. Existing pipes has to be cut since they are soldered so I must find out what to do with the coolant.

hello 
A few years ago we replaced the evaporator there was a leak in the tube and oil was leaking 
There’s a bolt ( look manual not easy to reach) who keeps the compressor in place. Once this bolt loose you can slide the compressor out the metal sleeve in to the locker under the stove .the tubes are long enough to do this but not complete outside the locker.
We have to cut the tubes and make the soldering in to the small locker under the stove.
Two things to take care of 
The gastube in the locker under the stove and not to get small particles of copper in to the tubes by cutting they will destroy the compressor
