Freeze-Time Correction Chart 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 S4 Dip Switch Setting Pump-Out Frequency 1st Pump-Out "J" Control Board OFF Every 10 cycles After 11th freeze cycle ON Every cycle After 2nd freeze cycle No. 5 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. 2. Shutdown Diagnosis 1) See "II.E.1. Bin Control Check." 3. Freeze-Time Correction Cycle Diagnosis 1) See "II.C. Freeze-Time Correction Cycle." Legend: BC–bin control; CB–control board; Comp–compressor; CR–compressor relay; CT–control transformer; CV–check valve; FM–fan motor; FMR–fan motor remote; FS–float switch; HGV–hot gas valve; HM–headmaster (C.P.R.); HPS–high-pressure switch; LLV–liquid line valve; MC–magnetic contactor; PM–pump motor; TXV–thermostatic expansion valve; WRV–water regulating valve; WV–inlet water valve 25 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: Number of Freeze Cycles Differential Value in Sec. 3 4 5 6 7 8 9 10 254 309 349 380 406 427 446 462 26 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.

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. Legend: CB–control board; CT–control transformer 28 E. Bin Control Check 1. Bin Control Check This appliance uses a lever-actuated proximity switch to control the ice level in the storage bin. No adjustment is required. To check BC, 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 control box cover, then clear any ice away from BC. Connection Detail Wire Harness 4) Check BC wire harness connections. See Fig. 1. Connector B 5) Disconnect BC connector from CB K4 connector.

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. Float Switch Assembly Ice Chute Fig. 3 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. Legend: CB–control board; FS–float switch 31 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.

Settings and Adjustments NOTICE Dip switches are factory set. Failure to maintain factory settings may adversely affect performance and warranty coverage. For more information, contact your Hoshizaki Service Center. 1. Default Dip Switch Settings The dip switches are factory-adjusted to the following positions for both the 2A7664-01 and 2A7664-02 control boards: S4 Dip Switch S4 Dip Switch No. 1 2 3 4 5 6 7 8 9 10 KM-1301S_J KM-1601S_J/3 ON OFF OFF OFF OFF OFF ON OFF OFF OFF KM-1301S_J3 OFF OFF OFF OFF OFF OFF ON OFF OFF OFF KM-190S_J/3 KM-2200S_J3 KM-2600S_J3 OFF OFF OFF OFF ON OFF ON OFF OFF OFF S5 Dip Switch (Do Not Adjust) S5 Dip Switch No. 1 All 2 3 4 5 OFF OFF OFF OFF ON Freeze Timer (9 & 10) Factory Use (8) Harvest Pump Time (Harvest Assist) and Freeze-Time Correction (7) (Do Not Adjust) Harvest Pump Time Timer (Harvest Assist) (6) Pump-Out Frequency Control (5) Pump-Out Time (3 & 4) Harvest Timer (1 & 2) 1 2 3 4 5 S5 Dip Switch (Do Not Adjust) "J" Control Board ON 1 2 3 4 5 6 7 8 9 10 ON S4 Dip Switch "J" Control Board Anti-Slush (5) Minimum Harvest Time (4) Refill Counter (2 and 3) Float Switch Selector (1) 42 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. Time (sec.) S4 Dip Switch Setting No. 1 No. 2 S5-4 OFF S5-4 ON OFF OFF 60 30 ON OFF 90 45 OFF ON 120 60 ON ON 180 75 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. S4 Dip Switch Setting Time (sec.)

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. S4 Dip Switch Setting Pump-Out Frequency 1st Pump-Out OFF Every 10 cycles After 11th freeze cycle ON Every cycle After 2nd freeze cycle No. 5 5. Harvest Pump Time (Harvest Assist) (S4 dip switch 6) NOTICE Factory set for proper operation. Do not adjust. Adjustment outside of the factory default setting may result in damage to the appliance. Harvest pump time (harvest assist) is only active when S4 dip switch 7 is in the "ON" position. In the factory default position, the harvest pump time (harvest assist) starts with 50 sec. left to go in harvest cycle (S4 dip switche 6) and after the thermistor reaches 48°F (9°C) at the evaporator outlet and the control board reads 3.9 kΩ from the thermistor. The harvest pump time (harvest assist) is factory set, and no adjustment is required. S4 Dip Switch Setting Harvest Pump Time (Harvest Assist) No. 6 S5-4 OFF S5-4 ON OFF 50 sec. 25 sec. ON 25 sec. 15 sec. 44 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. See "II.C. Freeze-Time Correction Cycle (90 min.)." S4 Dip Switch Setting Harvest Pump Time (Harvest Assist) No. 7 Freeze-Time Correction (CB: 2A7664-02) OFF Disabled ON Enabled 7. Factory Use (S4 dip switch 8) Factory set for proper operation. Do not adjust. This must be left in the factory default position. 45 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. S4 Dip Switch Setting No. 9 No. 10 Time (min.) OFF OFF 60 OFF ON 50 ON OFF 70 ON ON 75 9.

Anti-Slush (S5 dip switch 5) This dip switch setting provides anti-slush control during the freeze cycle. When the evaporator temperature reaches 36°F (2.2°C) the control board reads a 5.8kΩ signal from the thermistor and de-energizes the water pump for 10 sec. to melt ice slush and prevent ice slush from blocking the water supply tubing, causing irregular freeze patterns. NOTICE Factory set for proper operation. Do not adjust. Adjustment outside the factory default setting may result in damage to the appliance. S5 Dip Switch Setting No. 5 Anti-Slush OFF Disabled ON Enabled 47 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 B. Component Service Information NOTICE When replacing a component listed below, see the notes to help ensure proper operation. Component Notes Compressor 1 phase: Install a new start capacitor, run capacitor, and start relay. 3 phase: Install a new magnetic contactor. Thermostatic Expansion Valves • Attach the thermostatic expansion valve bulb to the suction line in the same location as the previous bulb. • The bulb should be between the 10 and 2 o'clock positions on the tube. • Secure the bulb with the clamp and holder, then insulate it. Hot Gas Valves Liquid Line Valves • Replace the strainer if applicable. Fan Motors Install a new capacitor. Pump Motor Install a new capacitor. Thermistor • Attach the new thermistor to the suction line in the same location as the previous thermistor. • Use copper tube of the same diameter and length when replacing valve lines. • The thermistor should be at the 12 o'clock position on the tube. • Smoothly fill the recessed area of the thermistor holder with high thermal conductive type sealant. Hoshizaki America part number 4A0683-01 (Silicone Heat Sink Compound 10-8108 manufactured by GC Electronics), KE-4560 RTV (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. Adjustment Screw CW – Lower CCW – Higher Top View Fig. 6 52 V.
