If your refrigerator or freezer is
not operating properly, use the
following guide before calling
your Sub-Zero Factory
Authorized Service Center or
dealer. The guide will save you
time and trouble, and may avoid
the expense of a service call.
The SERVICE light is on
steady
• The microprocessor has sensed
a problem with the operating
system. There may be
instructions in the display
window to solve the problem.
If not, call the Sub-Zero
Customer Service Department.
The SERVICE light is
flashing
• This happens when one or
more of the zones run too long
or there is a faulty temperature
sensor. If this occurs, turn the
unit off with the ON/OFF key
and they restart by depressing
the key again. If the light is
still flashing, call the Sub-Zero
Customer Service Department
or your Sub-Zero Factory
Authorized Service Center.
The SERVICE and ICE
lights are both flashing
• This occurs when the solenoid
valve for the icemaker is
activated too long. Check for
excess water near the icemaker.
If you see that, turn off the
water at the cut-off valve and
call for service. If there is no
excess water, turn the unit off
and back on to reset and see if
this corrects the lights. If they
continue to flash, call your
Sub-Zero Factory Authorized
Service Center.
The refrigerator/freezer
isn’t running
• Is there electrical power to the
unit (power outage)?
• Is your home circuit breaker or
fuse off?
• Is your refrigerator / freezer
control on?
• Is your condenser area clean?
• Has either door been left
open? (Be sure that food is not
obstructing proper door
closing).

it may be in defrost.
• Wait 30 minutes and try to
restart again.
The refrigerator/freezer
is warmer than usual

long time?
• Have you recently added a
large amount of food?
The refrigerator/freezer
runs for long periods
of time
• Is condenser area clean?
• On hot days and in warm room
temperatures the motor runs
