Refrigerators have been the bane of my existence. Bought a new Samsung, fairly high end model, a few years ago and barely outside of warranty it started going tits up. Replaced it with a Wirlpool again one of their higher end models and pretty much same deal just out of warranty and it has been giving me fits. The Samsung developed a refrigerant leak in the system and wouldn't freeze anything anymore and the Wirlpool keeps tuning off and I have to unplug it wait 30-60 sec. then plug it back in and everything is fine, well, until it acts up again.
I will say Samsung was good about it and through all the problems they ended up refunding my money in full for it. BUT, they certainly didn't make it easy and I had to stay after them to follow through with their promise to refund me about every 3-4 weeks for nearly six months before they finally sent me my refund. Wirlpool on the other hand basically told me oh darn sucks to be you now go away.
