Modular Icemaker; Modular Icemaker Operation - Sub-Zero 700-3 BASE Technical & Service Manual

Icemaker Information

MODULAR ICEMAKER

All 700-2 Series units utilize a "modular icemaker." The icemaker operation is not complex, however, an
understanding of its cycle of operation is necessary in order for a serviceman to make a proper diagnosis.

Modular Icemaker Operation

When the icemaker thermostat has sensed temperatures of 17°F, the thermostat closes. At this time, the current
now has a path through the thermostat to the motor. The motor is linked with the drive gear. From the module,
there are copper contacts that ride on copper strips on the backside of the drive gear. (See Figure 6-1) As the drive
gear rotates, these contacts from the module will make or break a circuit (track) to the copper strips to generate the
icemaker cycle.
