Monitor Icemaker System and Display If Service is Needed (Starting with Serial #2092137)
The microprocessor observes the 115 Volts AC supplied to the icemaker water valve solenoid. If the solenoid is
energized for more than 15 seconds, power to the icemaker system is disabled for 24 hours (See Figure 3-19), and
an error code is logged (EC 30). If this happens five consecutive times, ICE and SERVICE on the LCD will flash
and the ICE ON/OFF key will be disabled (See Figure 3-20).
NOTE: To clear the ICE and SERVICE error indicators, and reactivate the ICE ON/OFF key, the problem must be
corrected, then the unit must be switched OFF and back ON, and the Alarm key must be pressed for 15 seconds to
clear the Error Code.
NOTE: To allow ice
to freeze fully and
reduce effects of low
water pressure,
power to the icemak-
er system is interrupt-
ed for 45 minutes
after each ice har-
vest. This can be
bypassed for service
purposes by switch-
ing the icemaker sys-
tem OFF, then back
ON using the ICE
ON/OFF key.
NOTE: When in
Sabbath Mode, the
icemaker system is
disabled. Sabbath
Mode will be covered

#2092137, ICE and
SERVICE will flash if
If the solenoid is
energized for more
than 15 seconds, but
the ice making sys-
tem will not shut
down for 24 hours.
