I think some people here are overlooking the fact that your refrigerator leaked out ammonia in the freezer. I had that happen and the whole refrigerator had to be replaced.
I would not go with this simple??? DIY project suggested without checking with an expert.
why did the whole fridge have to be replaced? a normal adsorbtion fridge the cooling circut is all external, it is stuck on the back of the fridge and the cooling is transfered tyhrough metal heat sink contact.. so unless it is a weird model there is no way for it to leak inside the fridge..
