That’s subzero is more than 30 years old, and it will probably cost more than $30-40 a month to operate and it needs a serious repair.
Oh, yes, rip off the doors and scrap it... I agree, older Sub-Zeros were notorious for gas leaks and a host of other problems. Still, I just retired a pair of R/F201's built in 1979. The fridge worked perfectly, the freezer needed door seals, discontinued and I got tired of looking for generic ones... As long as the insulation isn't wet, the doors seal well, and the defrost system is working correctly, they can be as efficient as much newer units. They'll also outlast anything from any current manufacturer, period.
My former neighbors Ann and Russell bought a Sub-Zero when they built the house in 1985. She said it was a constant source of trouble, and wished they had just put the 1964 GE bottom freezer refrigerator in the kitchen.
Yeah, the bottom freezer Sub Zeros seemed to have a lot of gas leaks. I had friends in Delaware that bought one and regretted it almost immediately. Kept a can of R12 under it to top the thing off when the ice cream got soft every 6 months. We seem to have a lot of all-fridge all-freezers in Phoenix, I have a pair in a rental and my neighbor had a pair until recently. Those seem to be ok, other than occasional defrost issues and general wear over 30 years or so. They're a pain in the butt to work on, though, since the guts are mounted under rather than over the cold box. Nice place to collect dust, dog hair and scorpions, and a complete nightmare to replace even a simple condenser fan... Neighbor replaced his 601's with a pair of glass-door bottom freezers. Even getting a steal on the first one, in the end, he spent almost $20,000. I might have half that much in my whole kitchen, including the range, DW, fridge, 18" ice machine, cabinets, sink, faucet and granite!
Subzero refrigerator- freezershave two completely separate sealed systems in them.
For many years, they used a copper tube evaporator in the refrigerator section with aluminum fins. The copper would be attacked by the food acid in the refrigerator, and they had a great problem with leaks, the cure was to replace the evaporator with the newer, all aluminum one which had much fewer problems.
I don’t think I ever saw subzero with the freezer evaporator leaking, but I’m sure it’s possible.
They also had a condenser partially submerged in the defrost water pan under the unit that was usually on the freezer side, refrigeration system, those occasionally would get eaten through by the corrosive effects of the water in the pan and need to be replaced.
Subzero has not used fiberglass insulation since the 70s in the refrigerator so moisture in the insulation was not a big problem but the models from the 70s and 80s used two and three times as much electricity as current ones. There’s just no getting around that.
Newer models used more efficient, electronic fan motors for efficient compressors with run capacitors on them. They had better insulation in the box and the doors more intelligent programming for the defrost cycles, etc. the difference is dramatic. You can save as much as $50 a month at $.12 a kilowatt replacing one of the old ones with a new one.
