Update on SubZero repairs
I got some good advice here about my SZ fridge that a repairman had labelled: Not worth repairing. As suggested, I called the SZ customer service and they directed me to an authorized repair service. They came, looked, and have given me a repair price of just under $1,500. I'm thrilled! The alternative was a $10,000 new fridge with all kinds of problems fitting the new fridge into the built in kitchen. So, thanks for those who took the time to respond to my original post.
