Where can literature, experience, technical info be found regarding the repair of small absorption fridges (mostly Electrolux made)?
The most common advice they give is turn it upside down for some hours and then turn it again and switch it on.
But on a very small Dutch forum I co-moderate, there's a person asking how you need to recharge these.

I don't have a clue what's in it and in what proportions.

What's the procedure to refill it?
