actually means.
The control board has lost the reading from the refrigerator evaporator thermistor, the sensor on the fresh food cooling coil. Sub-Zero calls this an open thermistor. Beyond a power reset, there is nothing an owner can do.

Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for 10 R 00 on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Turn off the unit's breaker at the home panel for 30 seconds, then turn it back on.
Watch whether the code comes back and whether the fresh food section holds temperature.
If the code returns, book a service visit and give them the full three-part code.
What not to do
It is not the freezer sensor. That code is 10 F 00, and the letter in the middle tells you which section it is.
