Either the fridge needs to be replaced or the cooling unit has to be replaced. It's $$$ either way. I just had my cooling unit replaced and there is still a lingering ammonia smell, but it's cold and working. After reading "ronfisherman" 's response, I am wondering if the technicians didn't do a good cleaning job when the pulled the fridge out. Has anyone else had this problem? TIA
