I have a 12 year old GE refrigerator I bought new when I moved into this house. It has never given me any problem as far as keeping things cold or frozen. Ice maker always worked flawlessly too. Once in a blue moon I might clean out the disgusting amounts of lint that collect underneath and behind it. But I've noticed the compressor runs a lot on it, seems to run more than it does not run. Since it has always worked fine inside I figured it was just how it goes. After some recent heatpump work I have started to wonder if it might just need a freon charge and am so dumb I don't know if this is done for refrigerators.
