Question about Sub-Zero Refrigerators
Our is doing the same thing, except we do not have ice forming on the back of the freezer. We were told by a refrigeration repair company that if ice is forming on the back of the freezer then the compressor is bad.

The Control Center monitors refrigerator and
freezer temperatures as well as the ice maker
system. If there is a temperature or ice maker
problem, you'll be alerted by a flashing
SERVICE indicator light. This same SERVICE
light will also flash if the condenser needs
cleaning. Before calling for service, please
check and see if your condenser area needs
cleaning. Refer to Condenser Cleaning,
In all Built-In models, the condenser is located
behind the grille. First, remove the grille. Then
using a soft bristle brush, vacuum to remove
dust and lint from the condenser. NOTE: To
avoid bending the condenser fins, be sure to
vacuum in the direction of the fins (up and
down). Clean the condenser area every three
to six months.
Before cleaning the unit, shut the electricity
off at the control panel. When you
clean the condenser, wear gloves to avoid
injury from the sharp condenser fins.
Failure to clean the condenser could
result in temperature loss or mechanical
failure or damage.

I'm sorry to hear that your unit has a 'Service' indicator flashing. This message is displayed when the unit has had to run for an excessive period of time. This means that your unit is having difficulty cooling and as a result is running more often than normal.
My first suggestion would be that you turn off your unit and clean your condenser. Cleaning your condenser on a regular basis will help keep your unit running efficiently. While your compressors run, air is drawn through the condenser area where dust and/or pet hair can collect. Our recommendation is to vacuum this area at a minimum twice a year. Failure to do so could result in temperature loss, mechanical failure, or damage. Turn off the unit when you clean the condenser. This will reset the 'Service' indicator.
You will find instructions on how to vacuum your condenser in your Use & Care Manual. We also offer a video that provides clear instructions on our website, which you can view by following the enclosed link:
After trying this, if your unit is still having problems keeping temperature or if the service light has come back on, I would recommend that you contact a Factory Certified Service company.
