Service
Icemakeroperation
Follett’s icemaker consists of four distinct functional systems:
• Refrigeration system
• Water system
• Harvesting system
• Electrical control system
These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these
systems will result in improper operation of the entire ice production cycle. When troubleshooting the icemaker, it is
important to analyze the entire system operation to determine which system is not functioning properly, then pinpoint
the component within that system that is malfunctioning. Determine what corrective action must be taken before
making any adjustments or replacing any components.
Theicemakingprocess
The Follett icemaker uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle.
Water is supplied to the evaporator from the water reservoir where the water level is controlled by a oat valve.
This valve also shuts off the water supply when the icemaker is not running.
When the icemaker is running, a layer of ice
forms on the interior surface of the evaporator.
This ice is continuously removed by a slowly
rotating (12 RPM) auger.
The auger carries the ice upward into the cavity
formed by the top bearing housing and the
compression loop, where it is compressed to
remove excess water.
When the ice reaches the desired hardness it
rotates within the cavity and is forced through
a discharge port and compression nozzle and
into the ice transport tube. The discharge tube
and compression nozzle are slightly restricted
to further compress the ice and produce the
desired hardness. As the formation of ice
continues, ice in the transport tube is pushed
through the tube to the storage compartment in
the ice dispenser.
A solid state control board, located in the
electrical box of the icemaker, controls the
normal operation of the icemaker and monitors
gearmotor torque. This control board will shut
down the icemaker should an over-torque
condition occur. It is very important that
you familiarize yourself with the operational
sequences detailed in this manual before
attempting to service the icemaker.

The water sensor veries water in the oat reservoir. The water OK LED (WTR) comes on. At the same time, the
gearmotor, compressor and condenser fan motor come on, lighting the drive LED (DR) and compressor LED (C). The
high initial current draw of the compressor run winding closes the contacts of the current relay energizing the start
winding through the run capacitor. The gearmotor is also started through a current style relay that is pulled in by the
initial high current draw of the run winding. The PWR, B-E and WTR LED remain on.

After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding. As
the compressor comes up to normal running speed, the compressor start relay contacts also open, dropping out the
start winding of the compressor. The icemaker is now in a normal icemaking mode. The icemaker will begin to produce
ice and continue to produce ice until the bin level control in the ice dispenser is satised. The PWR, B-E, DR, C and

Refrigerant replacement requirements
1. Non-contaminated refrigerant removed from any
Follett refrigeration system can be recycled and
returned to the same system after completing
repairs. Recycled refrigerant must be stored in a
clean, approved storage container. If additional
refrigerant is required, virgin or reclaimed
refrigerant that meets ARI standard 700-88 must be
used.
2. In the event of system contamination (for example,
a compressor burn out, refrigerant leak, presence
of non-condensibles or moisture), the system must
be repaired, evacuated and recharged using virgin
or reclaimed refrigerant that meets ARI standard
700-88.
3. Follett Corporation does not approve of recovered
refrigerants. Improper refrigeration servicing
procedures will void the factory warranty.
Evacuation
Evacuate the system to a level of 500 microns. When
the 500 micron level is reached, close valves and shut
down the vacuum pump. Allow the system to sit for
approximately 20 minutes. During this period the system
pressure should not rise. If the system pressure rises
and stabilizes there is moisture in the system and further
evacuation is needed. If the pressure continues to rise
check the system for leaks.

Ice capacity test
Icemaker production capacity can only be determined by
weighing ice produced in a specic time period.
1. Remove top panel and hopper lid of unit.
2. Weigh and record weight of container used to
catch ice.
3. Run icemaker for at least 15 minutes.
4. Catch ice for 15 or 20 minutes.
5. Weigh harvested ice and record total weight.
6. Subtract weight of container from total weight.
7. Convert fractions of pounds to decimal equivalents
(Ex. 6 lbs 8 oz = 6.5 lbs).
8. Calculate production using following formula:
1440 min. × wt. of ice produced =production capacity/
24 hr. period
Total test time in minutes
9. Calculated amount per 24 hours should be checked
against rated capacity for same ambient and water
temperatures in Ice Production Table (above).
