B. Service Diagnosis
WARNING
• The appliance should be diagnosed and repaired only by qualified service
personnel to reduce the risk of death, electric shock, serious injury, or fire.
• Risk of electric shock. Control switch in "OFF" position does not de‑energize all
loads Use extreme caution and exercise safe electrical practices.
• Moving parts (e.g., fan blade) can crush and cut. Keep hands clear.
• Before servicing the appliance, move the control switch to the "OFF" position and
turn off the power supply.
• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after the appliance is serviced. Make sure that none have fallen
into the dispenser unit/ice storage bin.
• Make sure all food zones in the appliance and dispenser unit/ice storage bin are
clean after service.
The diagnostic procedure is a sequence check that allows you to diagnose the electrical
system and components. Before proceeding, check for correct installation, proper voltage
per nameplate, and adequate water supply. Check CB using the steps in "II.D. Control
Board Check." Check dip switch settings to assure that S4 dip switch 3, 4, 7, 8, 9, 10 and
S5 dip switch 1 through 5 are in the factory default position. S4 dip switch 1, 2, 5, 6 are
cleaning adjustments and the settings are flexible. For factory default settings, see "III.C.1.
Default Dip Switch Settings."
Note: • When checking high voltage (115VAC), always choose a white (W) neutral wire to
establish a good neutral connection.
• On models with a main transformer, the neutral (W) is provided through MT.
To confirm a good neutral, check for 60VAC from white (W) neutral to ground
(GND). If 60VAC is present, neutral is good. If 60VAC is not present, check
208-230VAC main power supply to MT. If 208-230VAC is present, check MT
continuity.
• When checking voltage from the CB K1 connector (10 pin connector), pull CB
K1 connector out slightly to allow room for multimeter test leads contact.
1) Turn off the power supply, then access the control box. Move the control switch to the
"OFF" position. Clear any ice from BC.
2) Check that BC is closed and the 115VAC 10A fuse is good.
19
1. Operation Diagnosis
3) Power On: Turn on the power supply, then move the control switch to the "ICE" position.
A 5‑sec. delay occurs. CB red "POWER OK" LED and green "BC CLOSED" LED turn
on. If yellow "BC OPEN" LED is on (indicating a full bin), check BC. Move ice away from
BC actuator paddle. If yellow "BC OPEN" LED stays on, see "II.D. Bin Control Check.".
Note: • CB red "POWER OK" LED remains on unless the 10.5VAC power supply is
interrupted (K2 connector).
• Check CB using the steps in "II.C.Control Board Check."
• Confirm CB green "BC CLOSED" LED is on. If CB yellow "BC OPEN" LED is on,
remove ice from BC. If no ice is around BC and yellow "BC OPEN" LED is on,
see "II.D.2. Bin Control Check."
a) Power On Diagnosis: If CB red "POWER OK" LED is off, confirm 10A fuse is good.
Check for 115VAC at control switch #1 (BR) to neutral (W) then at control switch
#2 (P) to neutral (W). If 115VAC is present on #1 (BR) and not on #2 (P), replace
control switch. If 115VAC is present on control switch #2 (P), check for 115VAC at
HPS (P) to neutral (W) then HPS (BK) to neutral (W). If 115VAC is present at HPS
(P) and not at HPS (BK), HPS is open. See HPS Diagnosis below. If 115VAC is
present at HPS (BK), check for 10.5VAC at CB K2 #1 red wire to CB K2 #2 red wire.
If 10.5VAC is not present, check that the cleaning valve interlock switch is closed.
Next, check CT continuity. If open, replace CT.
b) HPS Diagnosis: Confirm condenser coil is not clogged or restricted. Let refrigeration
circuit pressures equalize. If HPS does not reset and pressures are equalized,
replace HPS. If pressures are not equalized, reclaim refrigerant and diagnose
refrigeration circuit restriction. Check that there are no restrictions in the refrigeration
circuit.
Harvest Cycle: HGV, strainer, or check valve.
Freeze Cycle: FM, FMR, TXV, HM, LLV, WRV, strainer, check valve, drier, damaged
line set or fitting, and fan blade for binding.
Confirm that the location meets installation requirements. See the appliance's
instruction manual for details.
4) 1-Min. Fill Cycle – LED 4 is on. WV and X11 relay energize. After 1 min., CB checks for
a closed FS. If FS is closed, the harvest cycle begins. If harvest cycle begins (Comp,
HGV, FMR energized), continue to step 5a. If FS is open, WV remains energized until
FS closes (low water safety protection during initial start up and at the end of each
harvest). Diagnosis: Check that water enters the water tank. If not, check that the water
supply line shut-off valve is open and screens or external filters are clear. Check for
115VAC at CB K1 #6 (O) to neutral (W). If 115VAC is not present, replace CB. If 115VAC
is present, and WV does not energize, check for 115VAC at WV. If 115VAC is present,
check coil continuity. If open, replace WV. If the water tank fills, but the appliance fails to
start harvest (Comp energized), check for open FS. See "II.E. Float Switch Check and
Cleaning." If FS is closed and CB fails to start the harvest cycle after 1 min., replace CB.
20
5a) Initial Harvest Cycle – LEDs 1, 4, and 2 are on. WV and X11 relay continue. Comp,
FM* (if connected to CB K1 connector pin #9), FMR, HGV, and X10 relay energize.
CB monitors the warming of the evaporator via the thermistor located on the suction
line. When the thermistor reaches 48°F (9°C), CB reads 3.9 kΩ from the thermistor
and turns harvest termination over to the harvest timer (S4 dip switch 1 & 2 and S5 dip
switch 4). WV and X11 relay are energized during harvest for a maximum of 6 min. or
the length of harvest minus HPT setting (S4 dip switch 6), whichever is shorter. See
step 5b below.
a) Comp Diagnosis: Check that evaporator is warming. If not, confirm that Comp
energizes. If not, check for 115VAC at CB K1 #1 (V) or #9 (V) to neutral (W).
If 115VAC is not present, check for 115VAC at CB K1 #7 (BR) or #10 (BR) to neutral
(W). If 115VAC is present at #7 (BR) or #10 (BR) and not at #1 (V) or #9 (V), replace
CB. If 115VAC is present, check for 115VAC at CR or MC solenoid. If 115VAC is
present, confirm contacts are closed. If not, replace CR or MC. If CR or MC contacts
are closed, check Comp external overload, Comp start and run capacitors, Comp
start relay, and Comp motor winding.
b) HGV Diagnosis: If Comp is energized and evaporator is not warming, check that
HGV energizes and opens. Check for 115VAC at CB K1 #2 (P) to neutral (W).
If 115VAC is not present and LED 2 is on, replace CB. If 115VAC is present, check for
115VAC at HGV coil and check HGV coil continuity. Replace as needed.
c) LLV Diagnosis: Confirm that LLV is de-energized and closed (not bypassing).
If energized, replace CB. If de-energized and bypassing, replace LLV.
d) FM* Diagnosis (if connected to CB K1 connector pin #9):
KM-1301SAJ3: Check that FM* is energized and fan blades are turning. If not, check
FM* capacitor, motor winding, and fan blade for binding. Note: FM* is energized at
full speed RPMs (1600) during the harvest cycle and only capable of 1 speed.
KM-1601SAJ/3: Check that FM* is energized and fan blades are turning. If not, check
FM capacitor, motor winding, and fan blade for binding. Note: KM-1601SAJ/3 FM* is
capable of 2 speeds and is energized at slower RPMs (700) during the harvest cycle
through the fan speed control pressure switch. If FM* is operating at high-speed
RPMs (1600) during the harvest cycle, check condition of the fan speed control
pressure switch.
When open, head pressure <190 +- 10 PSIG RPMs at 700.
When closed, head pressure >250 +- 10 PSIG RPMs at 1600.
e) WRV Diagnosis: Confirm WRV is not leaking by. If WRV is leaking by, confirm HGV
is open and LLV is closed. Next, check for proper refrigerant pressures. If refrigerant
pressures are correct, adjust or replace WRV. See "IV.C. Water Regulating Valve
Adjustment (water‑cooled models)."
21
5b) Harvest Pump Time (Harvest Assist) – LEDs 1, 3, and 2 are on. When the
thermistor reaches 48°F (9°C), CB reads 3.9 kΩ from the thermistor and turns harvest
termination over to the harvest timer (S4 dip switch 1 & 2 and S5 dip switch 4).
When WV de-energizes, LED 4 turns off, X11 relay de-energizes and LED 3 turns on.
PM energizes. Comp, FM* (if connected to CB K1 connector pin #9), FMR, HGV, and
X10 relay continue.
Diagnosis: Place a thermometer on the suction line next to the thermistor. Has it
warmed to 48°F (9°C) or warmer? Confirm thermistor status. See "II.F. Thermistor
Check." If the thermistor reading is in proper range, dip switch 7 is on, and PM does
not energize before harvest terminates, replace CB. If WV continues, check for 115VAC
at CB K1 #6 (O). If 115VAC is present, and LED 4 is off, replace CB. If LED 3 is on
and PM is not energized, check for 115VAC at CB K1 #5 (DBU). If 115VAC is not
present, replace CB. If 115VAC is present and PM is not energized, check for 115VAC
at X10 relay terminal #7 (Y) to neutral (W). If 115VAC is not present, check for 115VAC
at X10 relay terminal #3 (P) to neutral (W) and X10 relay terminal #5 (Y) to neutral (W).
If 115VAC is present on terminal #3 (P) and not on terminal #5 (Y), replace X10 relay.
If 115VAC is present on X10 relay terminal #7 (Y) and PM is not energized, check for
115VAC at X10 relay terminal #4 (R) to neutral (W) and terminal #6 (DBU) to neutral
(W). If 115VAC is present on terminal #6 (DBU) and not on terminal #4 (R), replace
X10 relay. If 115VAC is present on X10 relay terminal #4 (R), check control switch
contact continuity between terminals #4 (R) and #5 (R). If contacts are open, replace
control switch. If contacts are closed and 115VAC is present between control switch
terminal #5 (R) and neutral (W), check PM capacitor and motor winding continuity.
5c) Initial Harvest Cycle Termination Diagnosis: When the thermistor reaches 48°F
(9°C), CB reads 3.9 kΩ from the thermistor and turns harvest termination over to
the harvest timer (S4 dip switch 1 & 2 and S5 dip switch 4). Check discharge line
temperature. For a thermistor check, see "II.F. Thermistor Check." If 1-min. fill cycle
starts after harvest timer terminates, check that FS is clean and operating properly, see
"II.E. Float Switch Check and Cleaning." If FS is closed, CB proceeds to the next cycle.
If not, replace CB.
Note: The minimum total time allowed by CB for a complete harvest cycle is based on
S5 dip switch 4. Maximum harvest time allowed is 20 min.
NOTICE! S4 dip switch 7 must remain on. Otherwise, PM will not energize during
the last seconds of harvest.
6) Freeze Cycle – LED 1 is on. Comp, FM* (if connected to CB K1 connector pin #9),
FMR, and PM continue. FM (if not connected to CB K1 connector pin #9) and LLV
energize. HGV and X10 relay de‑energize. Appliance is held in freeze by a 5-min. short
cycle protection timer. After 5-min. short cycle protection timer terminates and FS opens,
freeze cycle terminates.
Note: PM power supply switches from CB K1 #5 (DBU) in harvest to K1 #4 (R) in freeze.
Anti-Slush: When anti-slush is enabled (S5 dip switch 5 "ON"), PM de-energizes when
thermistor reaches 36°F (2.2°C) (5.8kΩ) for 10 sec. then, energizes for the remainder of
the freeze cycle.
22
a) Freeze Cycle Diagnosis: Confirm Comp, FM* (if connected to CB K1 connector pin
#9), FMR, and PM continue. Confirm that FM (if not connected to CB K1 connector
pin #9) and LLV energize. Confirm WRV opens. Next, confirm HGV and X10 relay
de-energize. During the first 5 min. of freeze, confirm evaporator is cooling. If not,
confirm WV de-energized (not leaking by), HGV de-energized (not bypassing), LLV
and FM (if not connected to CB K1 connector pin #9) energize, TXV and HM operate
correctly, WRV opens, Comp is efficient, and refrigerant charge is correct. See
"VIII.A. Specification and Performance Data."
b) Comp, FM*, and FMR Diagnosis: If Comp. FM* (if connected to CB K1 connector
pin #9), and FMR de-energize once freeze begins, check that appliance has not
shut off on HPS ("POWER OK" LED off). If so, check "3)b) HPS Diagnosis" above.
If "POWER OK" LED is on, check for 115VAC at CB K1 #1 (V) or #9 (V) to neutral
(W). If 115VAC is not present and LED 1 is on, replace CB.
Comp: If 115VAC is present, check for 115VAC at CR or MC coil. If 115VAC is
present, check CR or MC coil and contact continuity. Replace as needed. If CR or
MC is okay, check Comp start relay and start and run capacitors. Next, check Comp
motor winding continuity. If Comp is energized but evaporator is not cooling, check
for an inefficient Comp. See "VIII.A. Specification and Performance Data."
FM*: If Comp is energized but FM* is not, check capacitor, motor winding, and fan
blade for binding.
FMR: If Comp is energized but FMR is not, check for 115VAC at the FMR junction
box. If 115VAC is not present, check icemaker wiring connections. If 115VAC is
present, check for voltage at condenser unit. If 115VAC is not present, check field
wiring connections. If 115VAC is present, check FMR capacitor, motor winding, and
fan blade for binding.
c) WV and HGV Diagnosis: If WV is energized, check for 115VAC at CB K1 #6 (O) to
neutral (W). If 115VAC is present after PM energizes in harvest cycle, replace CB.
If 115VAC is not present, replace WV (bypassing). If HGV did not close at the end of
harvest, check for 115VAC at CB K1 #2 (P) to neutral (W). If 115VAC is present and
LED 3 is off, replace CB. If 115VAC is not present, replace HGV (bypassing).
d) PM Diagnosis: Confirm water is flowing over evaporator from PM and not WV. If PM
de-energizes once freeze begins, check for 115VAC at CB K1 #4 (R) to neutral (W).
If 115VAC is not present, replace CB. If 115VAC is present and PM is de-energized,
check for 115VAC at control switch #5 (R) to neutral (W). If 115VAC is present at CB
K1 #4 (R) and not at control switch #5 (R), check control switch continuity between
#5 (R) and #4 (R). Replace as needed. If 115VAC is present at control switch #5 (R)
to neutral (W), check PM capacitor and motor winding continuity.
e) FM and LLV Diagnosis: If FM (if not connected to CB K1 connector pin #9) or LLV
does not energize, check for 115VAC at CB K1 #3 (BK) to neutral (W). If 115VAC is
not present, replace CB. If 115VAC is present:
For FM, check capacitor, motor winding, and blade for binding.
For LLV, check coil voltage and continuity.
23
f) Refrigerant Pressures, HM, and TXV Diagnosis: If evaporator is still not cooling,
check refrigerant pressures. See "VIII.A. Specification and Performance Data."
Next, check HM operation. If refrigeration pressures are above HM setpoint and
HM is bypassing, replace HM. Check TXV for proper operation. Remove TXV bulb
and hold it in your hand, refrigerant low-side pressure should rise, place TXV bulb in
ice water, refrigerant low-side pressure should drop. A 10 to 15 pound pressure swing
between warm and cold conditions indicate a good TXV. If a 10 to 15 pound swing is
not present, replace TXV.
g) WRV Diagnosis: WRV is factory set and generally no adjustment is required.
If WRV fails to open in freeze, check for proper refrigerant pressures. See "VIII.A.
Specification and Performance Data." If refrigerant pressures are correct and WRV
does not open, adjust or replace as needed. See "IV.C. Water Regulating Valve
Adjustment (water‑cooled models)."
h) Freeze Termination Diagnosis: After 5 min. in freeze, disconnect CB K5 FS
connector. 15 sec. later appliance should switch out of the freeze cycle (15 second
delay after FS opens before terminating the freeze cycle). If appliance remains in
freeze longer than 15 sec. after FS removed, replace CB. If appliance switches with
FS removed but would previously not switch out of freeze with FS connected (long
freeze - 3 beep alarm), see "II.E. Float Switch Check and Cleaning."
Note: Normal freeze cycle will last 20 to 40 min. depending on model and conditions.
Cycle times and pressures should follow performance data provided in this
manual. See "VIII.A. Specification and Performance Data."
i) Short Freeze Cycle Diagnosis: Confirm water tank fills and overflows during fill and
harvest cycles. If not, check water supply filters, shut-off valve, WV screen. If water
tank empties before 5 min. timer terminates and freeze cycle is short, check that CV
is not leaking by (water flowing down the potable drain). If CV is leaking by, remove
and clean CV, replace rubber seat and spring if necessary. If water tank is full, see
"II.E. Float Switch Check and Cleaning." for erratic FS.
7) Pump-Out Cycle – LEDs 1, 3, and 2 are on (10/20 second pump-out). Timing of the
first pump-out is determined by S4 dip switch 5. See the table below.
"J" Control Board Settings

Comp, FM* (if connected to CB K1 connector pin #9), and FMR continue, HGV
energizes. If S4 dip switch 3 & 4 are set to 3 off and 4 on, LED 4 turns on and WV
and X11 relay energize, energizing X10 relay. NOTICE! S4 dip switch 3 & 4 must
not be set to 3 off and 4 on. Otherwise, PM will rotate in freeze cycle direction
instead of pump-out direction. FM (if connected to CB K1 connector pin #3) and
LLV de‑energize. PM stops for 2 sec., then reverses for 10/20 sec. depending on
pump‑out timer (S4 dip switch 3 & 4) setting. When the pump‑out timer terminates,
24
pump‑out is complete. The pump-out frequency control (S4 dip switch 5) is factory set,
and generally no adjustment is required. However, the pump‑out frequency control can
be set to have a pump-out occur every 10 cycles or every cycle. For details, see "III.C.4.
Pump‑Out Frequency Control (S4 dip switch 5)."
Pump-Out Diagnosis: In the freeze cycle before pump-out (see table above), after
5 min. of freeze disconnect CB black K5 connector (FS connector). Check that PM
stops and re-starts. Next, check that PM rotation is correct (water flowing down the
drain through CV). If PM does not stop and re-start, check that CB LEDs 1, 3, and
2 are on. If not, replace CB. If LEDs 1, 3, and 2 are on and PM does not energize,
check for 115VAC at CB K1 #5 (DBU) to neutral (W). If 115VAC is not present, replace
CB. If 115VAC is present, check that X10 relay is de-energized. If not, check X11 relay
status. If X11 relay is energized, replace CB. If X11 relay is de-energized and X10 relay
is energized, replace X11 relay (contacts sticking). If X10 relay is de-energized, check
for 115VAC at terminal #6 (DBU) to neutral (W) and terminal #2 (DBU) to neutral (W).
If 115VAC is present on terminal #6 (DBU) and not on terminal #2 (DBU), replace
X10 relay. If PM is energized and rotating in pump-out rotation, make sure the drain line
is not clogged and that CV is clean and operating properly.
Confirm FM (if connected to CB K1 connector pin #3) and LLV de-energize. If FM is
energized, confirm where FM is connected on CB. If connected to CB K1 connector
pin #9, FM should be energized. If connected to CB K1 connector pin #3 and FM is
energized, replace CB. If LLV is energized with LEDs 1, 3, and 2 on, replace CB.
8) Normal Harvest Cycle – Same as the initial harvest cycle. Return to step 5a) above.
Note: Appliance continues to cycle until BC is satisfied, power is switched off or
freeze‑time correction cycle is initiated. The appliance always restarts at the
1-min. fill cycle.

C. Freeze-Time Correction Cycle (90 min.)
Freeze-Time Correction function is enabled when S4 Dip Switch 7 is in the "ON" position
and initiates when the minimum and maximum freeze times have exceeded differential
parameters. Freeze-time correction timer and count starts at the beginning of the 2nd
freeze cycle after startup from power off condition. Freeze-time correction timer and count
continues and retains its freeze-time correction timer and count during a BC off cycle
and resumes its freeze‑time correction timer and count on the 2nd freeze cycle after BC
restart. If freeze‑time differential is exceeded (see table below), freeze‑time correction
cycle starts and CB red "POWER OK" LED blinks. When freeze‑time correction cycle
occurs 3 or more times within a 36 hour period, CB yellow "EXT HARVEST" LED blinks
with CB red "POWER OK" LED. Appliance starts in freeze cycle after a freeze‑time
correction cycle. To reset CB LEDs, press ALARM RESET button on CB with power on.
CB resets LEDs and appliance continues cycle without interruption.
1) Freeze Time Differential Initiation: CB starts monitoring freeze times on the second
freeze time. After 3 freeze cycles (4th total), CB begins to compare minimum and
maximum freeze time cycles. Every freeze cycle time after the first freeze cycle
time is added to the freeze time list. Minimum and maximum freeze time differential
comparisons begin on the third cycle and are monitored up to 10 cycles. On the 11th
cycle the first freeze cycle time is dropped to maintain the 10 maximum number of
cycles.
Example: After 8 cycles (excluding first cycle), if the differential between the
shortest cycle (minimum) and the longets cycle (maximum) is equal to or greater than
427 sec. a freeze-time correction cycle is initiated:

2) Freeze-Time Correction Sequence:
First occurrence within 36 hr., minimum and maximum freeze times have exceeded
differential parameters. CB "POWER OK" LED starts blinking. Freeze-Time Correction
Cycle starts.
Second occurrence within 36 hr., minimum and maximum freeze times have exceeded
differential parameters. If not reset, CB "POWER OK" LED continues blinking. If reset
from first occurrence, CB "POWER OK" LED starts blinking. Freeze-Time Correction
Cycle starts.
Third occurrence within 36 hr. minimum and maximum freeze times have exceeded
differential parameters. CB yellow "EXT HARVEST" LED starts blinking. Also, If not
reset, CB "POWER OK" LED continues blinking. If reset, CB "POWER OK" LED starts
blinking.Freeze-Time Correction Cycle starts.
Total freeze-time correction cycle last for 90 min. At the end of 80 min., the final step
initiates and final Harvest Pump Time (Harvest Assist) with WV (10‑min.) starts. Once
the final Harvest Pump Time (Harvest Assist) with WV (10-min.) terminates
(90 min. complete), normal freeze cycle begins.
2a) 10-Min. Harvest Pump Time (Harvest Assist) with WV: CB "POWER OK" LED
blinking. CB LEDs 1, 4, 3, and 2 are on and Comp, FMR, HGV, PM, and WV energize.
10-min. timer starts. Once 10‑min. timer terminates, CB LEDs 1, 3, and 2 turn off and
Comp, FMR, HGV, and PM de-energize. WV continues.
2b) 10-Min. Fill: CB LED 4 on and WV energized. 10-min. timer starts.
2c) Final 10-Min. Harvest Pump Time (Harvest Assist) with WV: CB "POWER OK" LED
blinking. Once 10‑min. timer terminates, CB LEDs 1, 4, 3, and 2 are on and Comp,
FMR, HGV, and PM energizes. WV continues. 10-min. timer starts. Once 10-min.
timer terminates, normal freeze cycle begins. CB LED 1 on and Comp, FMR, and PM
continue. HGV and WV de-energize.
Note: After 3rd Freeze-Time Correction Cycle in 36 hours, CB signals with blinking CB
yellow "EXT HARVEST" LED. Appliance continues normal operation.
CB "POWER OK" LED and CB yellow "EXT HARVEST" LED continue blinking in
normal operation sequence.
3) Appliance Cycle Reset and CB Alarm Reset:
Cycle Reset: Power supply or control switch turned off and on again: Appliance turns
off, then re-starts at 1.Fill Cycle.
Alarm Reset: CB "ALARM RESET" pressed during or after a freeze-time correction
cycle with power supply on: Appliance continues cycle with no interruption or reset.
CB red "POWER OK" LED blinking: CB red "POWER OK" LED resets to solid.
CB yellow "EXT HARVEST" LED blinking: CB yellow "EXT HARVEST: LED turns off.

D. Control Board Check
Before replacing CB that does not show a visible defect and that you suspect is bad,
always conduct the following check procedure. This procedure will help you verify your
diagnosis.
Alarm Reset: If CB is in alarm (beeping), press the "ALARM RESET" button on CB
while CB is beeping. WARNING! Risk of electric shock. Care should be
taken not to touch live terminals. Once reset, the icemaker starts at the
1-minute fill cycle. For audible alarm information, see "III.B. LED Lights and
Audible Alarm Safeties."
1) Check the dip switch settings to assure that S4 dip switch 3, 4, 7, 8, 9, 10 and S5 dip
switch 1 through 5 are in the factory default position. S4 dip switch 1, 2, 5 are cleaning
adjustments and the settings are flexible. For factory default settings, see "III.C.1.
Default Dip Switch Settings."
2) Move the control switch to the "ICE" position. If the red "POWER OK" LED is on, control
voltage is good, continue to step 3. If the "POWER OK" LED is off, check CT secondary
circuit. CT output is 10.5VAC at 115VAC primary input. If the secondary circuit has
proper voltage and the red LED is off, replace CB.
If the secondary circuit does not have proper voltage, check CT primary circuit. Check
for 115VAC at CB K1 connector pin #10 (BR) to neutral (W) for 115VAC. Always choose
a white (W) neutral wire to establish a good neutral connection when checking voltages.
For additional checks, see "II.G.1. No Ice Production."
3) The "OUTPUT TEST" button provides a relay sequence test. Make sure the control
switch is in the "ICE" position, then press the "OUTPUT TEST" button. For the correct
lighting sequence, see the table below. Note that the order of the LEDs from the outer
edge of the control board is 1, 4, 3, 2. Components (e.g., compressor) cycle during the
test.
Following the test, the icemaker begins operation at the 1-minute fill cycle. If the LEDs
do not light as described above, replace CB.
4) To verify voltage output from CB to the components, slide the CB K1 connector out far
enough to allow multimeter lead contact. With the icemaker in the cycle to be tested,
check output voltage from the corresponding pin on CB K1 connector to a neutral
(W wire). If output voltage is not found and the appropriate LED is on, replace CB.
5) Confirm BC communication and shutdown sequence: Move the control switch to the
"ICE" position. Once the fill cycle starts press and hold the BC actuator paddle. CB
shuts down the appliance after 15 sec.. If not, confirm BC status. See "II.E.1. Bin Control
Check." If BC checks ok, replace CB.

2. Bin Control Cleaning
Scale may build up on BC. Scale can cause the actuator paddle and magnet to stick. In
this case, BC should be cleaned.
WARNING
CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after the icemaker is serviced. Make sure that none have fallen

F. Float Switch Check and Cleaning
FS is used to determine that there is sufficient water in the water tank after the 1‑min.
fill cycle and after each harvest cycle. FS is also used to determine that the appropriate
volume of water has been converted into ice before switching out of the freeze cycle. No
adjustment is required.
1. Float Switch Check
To check FS, follow the steps below.
1) Turn off the power supply.
2) Remove the front panel, then move the control switch to the "OFF" position.
3) Remove the insulation panel, then remove the drain plug located on the lower front part
of the ice chute. See Fig. 3. Allow the water tank to drain.
4) Replace the drain plug in its correct position. Be careful not to cross thread it.
5) Remove the control box cover.
Cleaning Valve
Drain Plug
6) Disconnect FS connector from CB
K5 connector.
7) Check for continuity across FS leads. With
the water tank empty, FS should be open.
If open, continue to step 8. If closed, follow
the steps in "II.E.2. Float Switch Cleaning."
After cleaning FS, check it again. Replace if
necessary.
8) Reconnect FS connector to CB K5
connector, then replace the control box
cover in its correct position.

9) Move the control switch to the "ICE" position. Replace the insulation panel and front
panel in their correct positions, then turn on the power supply. After 1 min., the 1-min.
fill cycle should end and the initial harvest cycle should begin. If the initial harvest cycle
begins, FS is good and the check is complete. If the initial harvest cycle does not begin,
continue to step 10.
10) Turn off the power supply.
11) Remove the front panel. Move the control switch to the "OFF" position.
12) Remove the control box cover.
13) Disconnect FS connector from CB K5 connector.
14) Check for continuity across FS leads. With the water tank full, FS should be closed.
If FS is closed and the icemaker will not switch from the 1-min. fill cycle to the initial
harvest cycle, replace CB.
If FS is open, confirm that the water tank is full. If the water tank is not full, check the
water supply, water filters, and inlet water valve. If the water tank is full, follow the
steps in "II.E.2. Float Switch Cleaning." After cleaning FS, check it again. Replace if
necessary.

2. Float Switch Cleaning
Depending on local water conditions, scale may build up on FS. Scale on the switch can
cause the float to stick. In this case, FS should be cleaned.
1) Turn off the power supply.
2) Remove the front panel, then move the control switch to the "OFF" position.
3) Remove the insulation panel, then remove the drain plug located on the lower front part
of the ice chute. See Fig. 3. Allow the water tank to drain.
4) Replace the drain plug in its correct position. Be careful not to cross thread it.
5) Disconnect the vent tube and the flush tube from the top of FS, then remove FS
assembly and remove the rubber boot from the bottom of FS assembly. See Fig. 4.
6) Remove the retainer rod from the bottom of FS housing, then remove the float.
Be careful not to bend the retainer rod excessively when removing it.
7) Wipe down FS housing, shaft, float, and retainer rod with a mixture of 1 part Hoshizaki
"Scale Away" and 25 parts warm water. Clean the inside of the rubber boot and hose
with cleaning solution. Rinse the parts thoroughly with clean water.
8) Reassemble FS assembly and replace it and the rubber boot in their correct positions.
Reconnect the vent tube and the flush tube.
9) Move the control switch to the "ICE" position.
10) Replace the insulation panel and front panel in their correct positions.
11) Turn on the power supply to start the automatic icemaking process.

G. Thermistor Check
To check thermistor resistance, follow the steps below.
1) Turn off the power supply.
2) Remove the front panel. Move the control switch to the "OFF" position.
3) Remove the control box cover.
4) Remove the thermistor from the refrigerant tubing.
5) Immerse the thermistor sensor portion in a glass containing ice and water for 2 or 3 min.
6) Disconnect the thermistor connector from CB K3 connector and check the resistance
between thermistor leads. Normal range is 4.7 to 6.2 kΩ. If outside the normal range,
replace the thermistor. See "IV.B. Component Service Information." If within the normal
range, continue to the next step.
7) Replace the thermistor in its correct position. See "IV.B. Component Service
Information."
8) Reconnect the thermistor connector to CB K3 connector.
9) Replace the control box cover in its correct position.
10) Move the control switch to the "ICE" position.
11) Replace the front panel in its correct position.
12) Turn on the power supply.
13) Once the harvest cycle starts (Comp energizes), begin timing the harvest cycle.
14) The harvest timer and harvest cycle should terminate within 2 to 5 min. If the harvest
cycle does not terminate within 2 to 5 min., replace CB.

2. Harvest Time (S4 dip switch 1 & 2)
The harvest timer starts counting when the thermistor reaches 48°F (9°C) at the
evaporator outlet and the control board reads 3.9 kΩ from the thermistor. The harvest
timer is factory set, and generally no adjustment is required. However, a setting longer
than the factory setting may be advised in cases where the drain provided at harvest
needs to be prolonged for extra cleaning. Note that the pump-out timer (S4 dip switch
3 & 4) acts in place of the harvest timer during cycles with a pump out. For details, see
"III.C.3. Pump-Out Timer (S4 dip switch 3 & 4)."
Note: On models with a pump-out every cycle, the harvest timer is only relevant during
the initial harvest cycle since a pump out occurs every cycle thereafter.

3. Pump-Out Time/Harvest Time During Pump-Out (S4 dip switch 3 & 4)
NOTICE
Do not adjust 3 off and 4 on. Pump motor does not run in pump-out rotation in this
setting.
When a pump-out is called for, the pump motor stops for 2 sec., then energizes in the
reverse direction, taking water from the bottom of the water tank and forcing pressure
against the check valve seat allowing water to go through the check valve and down
the drain. At the same time, water flows through the small tube to power flush the float
switch. The pump motor drains the water tank for the time determined by the pump-out
timer. The pump‑out timer also acts in place of the harvest timer during cycles with a
pump‑out. The pump-out timer is factory set, and generally no adjustment is required.
However, where water quality is bad and the icemaker needs a longer pump-out time,
the pump‑out timer can be adjusted. The pump‑out time can be set to pump-out for 10 or
20 sec. During pump-out cycles minimum harvest time is based on times given in the
table below.

4. Pump-Out Frequency Control (S4 dip switch 5)
The pump-out frequency control is factory set to drain the water tank every 10 cycles.
Generally no adjustment is required. However, where water quality is bad and the
icemaker needs a pump-out more often, the pump‑out frequency can be adjusted. The
pump-out frequency control can be set to have a pump‑out occur every cycle, or every
10 cycles.
The first pump-out is dependent on S4 dip switch 5. See the table below.

6. Harvest Pump Time (Harvest Assist)/Freeze-Time Correction (S4 dip switch 7)
NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside of the factory
default setting may result in damage to the appliance.
a) Harvest Pump Time (Harvest Assist)
Depending on S4 dip switch 7 setting, the pump motor either stays off or is energized
during the last seconds of the harvest cycle. When the pump motor is energized (S4 dip
switch 7 on), water circulates over the evaporator. The harvest water valve is open during
harvest for a maximum of 6 minutes or the length of harvest minus the harvest pump
time value(S4 dip switch 6), whichever is shorter.
When S4 dip switch 7 is in the on position and harvest begins, X11 and X10 relays
energize. A latching circuit is created through the X11 and X10 relays. For further
details, see "VIII.B. Wiring Diagrams." In the factory default position, 50 sec. before
harvest termination, LED 4 turns off, inlet water valve and X11 relay de‑energize. X10
relay remains energized through the latching circuit. Next, LED 3 turns on and control
board K1 connector pin #5 (DBU wire) energizes, energizing the pump motor for the
last seconds of harvest. Harvest pump time adjusted by S4 dip switch 1 & 2 and S5 dip
switch 4 settings. Contact Technical Support before adjusted these settings.
b) Freeze-Time Correction
When S4 dip switch 7 is in the on position, freeze-time correction enabled.

8. Freeze Timer (S4 dip switch 9 & 10)
NOTICE
Adjust to proper specification, or the icemaker may not operate correctly.
The freeze timer setting determines the maximum allowed freeze time to prevent
possible freeze-up issues. Upon termination of the freeze timer, the control board initiates
the harvest cycle or pump-out cycle. After 2 consecutive freeze timer terminations, the
control board shuts down the icemaker. In this case, see "II.G.3. Low Ice Production"
for possible solutions. The freeze timer is factory set and no adjustment is required.
Before changing this setting, contact Hoshizaki Technical Support at 1‑800‑233-1940 for
recommendations.

IV. Refrigeration Circuit and Component Service Information
WARNING
• This appliance should be diagnosed and repaired only by qualified service
personnel to reduce the risk of death, electric shock, serious injury, or fire.
• Move the control switch to the "OFF" position and turn off the power supply. Place
the disconnect in the "OFF" position. Lockout/Tagout to prevent the power supply
from being turned back on inadvertently.
• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after the icemaker is serviced. Make sure that none have fallen
into the dispenser unit/ice storage bin.
• Make sure all food zones in the icemaker and dispenser unit/ice storage bin are
clean after service.
A. Refrigeration Circuit Service Information
WARNING
• Repairs requiring the refrigeration circuit to be opened must be performed by
properly trained and EPA-certified service personnel.
• Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the system (if using an electronic leak detector), and then raise the
pressure using nitrogen gas (140 PSIG). Do not use R‑404A as a mixture with
pressurized air for leak testing.
NOTICE
• Always recover the refrigerant and store it in an approved container. Do not
discharge the refrigerant into the atmosphere.
• Do not leave the system open for longer than 15 min. when replacing or servicing
parts. The Polyol Ester (POE) oils used in R-404A applications can absorb
moisture quickly. Therefore it is important to prevent moisture from entering the
system when replacing or servicing parts.
• Always install a new drier every time the sealed refrigeration system is opened.
Do not replace the drier until after all other repair or replacement has been made.
Install the new drier with the arrow on the drier in the direction of the refrigerant
flow.
• When brazing, protect the drier by using a wet cloth to prevent the drier from
overheating. Do not allow the drier to exceed 250°F (121°C).
1. Refrigerant Recovery
The icemaker is provided with refrigerant service valves. Using proper refrigerant practices,
recover the refrigerant. Store the refrigerant in an approved container. Do not discharge the
refrigerant into the atmosphere.
48
2. Brazing
WARNING
• R-404A itself is not flammable at atmospheric pressure and temperatures up to
176°F (80°C).
• R-404A itself is not explosive or poisonous. However, when exposed to high
temperatures (open flames), R-404A can be decomposed to form hydrofluoric
acid and carbonyl fluoride both of which are hazardous.
• Do not use silver alloy or copper alloy containing arsenic.
1) Braze all fittings while purging with nitrogen gas flowing at a pressure of 3 to 4 PSIG.
Note: Because the pipes in the evaporator case are specially coated to resist corrosion,
it is important to make connections outside the evaporator case when possible. If
it is necessary to braze inside the evaporator case, use sandpaper to remove the
coating from the brazing connections before unbrazing the components.
NOTICE
• Always install a new drier every time the sealed refrigeration system is opened.
• Do not replace the drier until after all other repair or replacement has been made.
Install the new drier with the arrow on the drier in the direction of the refrigerant
flow.
• When brazing, protect the drier by using a wet cloth to prevent the drier from
overheating. Do not allow the drier to exceed 250°F (121°C).
2) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the system (if using an electronic leak detector), and then raise the
pressure using nitrogen gas (140 PSIG). Do not use R-404A as a mixture with
pressurized air for leak testing.
3. Evacuation and Recharge (R-404A)
1) Attach a vacuum pump to the system. Be sure to connect the charging hoses to both
high and low-side refrigerant access valves.
IMPORTANT
The vacuum level and vacuum pump may be the same as those for current
refrigerants. However, the rubber hose and gauge manifold to be used for
evacuation and refrigerant charge should be exclusively for POE oils.
2) Turn on the vacuum pump. Open the gauge manifold valves, then open the high and
low-side service valves. Never allow the oil in the vacuum pump to flow backwards.
3) Allow the vacuum pump to pull down to a 29.9" Hg vacuum. Evacuating period depends
on pump capacity.
4) Close the low-side valve and high-side valve on the gauge manifold.
49
5) Disconnect the gauge manifold hose from the vacuum pump and attach it to a
refrigerant service cylinder. Remember to loosen the connection and purge the air from
the hose. For the required refrigerant charge, see the rating label inside the icemaker.
Hoshizaki recommends only virgin refrigerant or reclaimed refrigerant which meets
ARI Standard 700 (latest edition) be used.
6) A liquid charge is required when charging an R-404A system (to prevent fractionation).
Place the service cylinder on the scales; if the service cylinder is not equipped with
a dip tube, invert the service cylinder, then place it on the scales. Open the high-side
valve on the gauge manifold.
7) Allow the system to charge with liquid until the proper charge weight is met.
8) If necessary, add any remaining charge to the system through the low-side.
NOTICE! To prevent compressor damage, use a throttling valve or liquid
dispensing device to add the remaining liquid charge through the low-side
refrigerant service valve with the icemaker running.
9) Close the high and low-side service valves, then close the high and low-side gauge
manifold valves. Disconnect the gauge manifold hoses.
10) Cap the refrigerant service valves to prevent a possible leak.
50

(manufactured by ShinEtsu Silicones), or equivalent are recommended.
• Secure the thermistor with the holder, then insulate it.
• Be very careful to prevent damage to the leads.
51
C. Water Regulating Valve Adjustment (water-cooled models)
The water regulating valve is factory set, and generally no adjustment is required. However,
when necessary, adjust the water regulator using the following procedure.
1) Prepare a thermometer to check the condenser drain temperature. Attach a pressure
gauge to the high-side line of the system.
2) 5 min. after a freeze cycle starts, confirm that the thermometer reads 104°F to 115°F
(40°C to 46°C). If it does not, rotate the adjustment screw by using a flat blade
screwdriver until the temperature is in the proper range (rotate counterclockwise to
raise temperature or clockwise to lower temperature). See Fig. 6. Next, check that the
reference pressure is in the range indicated in "VIII.A. Specification and Performance
Data." If it is not in the proper range, verify the refrigerant charge.
3) Check that the condenser drain temperature is stable.
