You need to be very careful when cleaning your fridge.  If you get the ice off the plate with something that could puncture the gas lines within the plate, this is not being very careful.  One of my fridges was not working, and actually found a honest refrigeration guy in Tahiti.  He said, yeah I could change some parts, but I don't think that's the problem.  The quick connect links (that only cost a few dollars) usually go bad, so let's change them and fill up back up and run it.  It worked!  Paid for an hour of time, little bit of gas, and two quick connect gaskets...  Still working 2.5 years later....  All for less than $100 dollar bill.  

Now, if you were in Le Marin. there's a 6' 2" French guy that will tell you you need a new refrigerator and installation which cost only $3500.
