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.
1. "E" and "G" Control Board without Harvest Pump Timer Diagnosis 3) Power On: Turn on the power supply, then move the control switch to the "ICE" position. A 5‑sec. delay occurs. • "E" Control Board: CB red "POWER OK" LED turns on. • "G" Control Board: CB red "POWER OK" LED and green "BC CLOSED" LED turn on. Note: • CB red "POWER" LED remains on unless the 10.5VAC power supply is interrupted (K2 connector). • Check CB using the steps in "II.C. Control Board Check.
4) 1-Minute Fill Cycle – LED 4 is on. WV energizes. After 1 min., CB checks for a closed FS. If FS is closed, harvest cycle begins. If harvest cycle begins (Comp, HGV, and FMR energize), continue to step 5. If FS is open, WV remains energized through additional 1‑min. fill cycles until water enters the water tank and 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.
e) 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). 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.
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.
7) Pump-Out Cycle – LEDs 1, 3, and 2 are on (10/20 second pump-out). Timing of the first pump-out is dependent on CB. "E" CB first pump‑out is after the first freeze cycle. "G" CB first pump-out is determined by S4 dip switch 5 & 6. See the table below. "E" & "G" Control Board Settings S4 Dip Switch Setting 1st Pump-Out Pump-Out Frequency "E" Control Board "G" Control Board After 1st freeze cycle After 2nd freeze cycle No. 5 No.
9) Shutdown a) "E" Control Board: Thermostatic Bin Control (TBC): When the appliance is running, hold ice in contact with the thermostatic bulb. TBC switch opens within 10 sec., shutting down the appliance. TBC is factory set, and generally no adjustment is required. However, adjustment may be needed in some conditions, particularly at higher altitude locations. NOTICE! Do not adjust S4 dip switch 7 out of the factory default position.
2. "G" Control Board with Harvest Pump Timer 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 MBC. Move ice away from MBC actuator paddle. If yellow "BC OPEN" LED stays on, see "II.D.2. Mechanical Bin Control (MBC) Check." Note: • CB red "POWER OK" LED remains on unless the 10.
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 through additional 1-min. fill cycles until water enters the water tank and 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.
5b) Harvest Pump Timer – 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). 50 sec. before the harvest timer terminates, LED 3 turns on and PM energizes. Comp, FMR, HGV, and X10 relay continue. LED 4 turns off, WV and X11 relay de‑energize. 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.
6) Freeze Cycle – LED 1 is on. Comp, FMR, and PM continue. FM 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. 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. a) Freeze Cycle Diagnosis: Confirm Comp, FMR, and PM continue. Confirm that FM and LLV energize. Confirm WRV opens. Next, confirm HGV and X10 relay de-energize.
f) Refrigerant Pressures, HM, and TXV Diagnosis: If evaporator is still not cooling, check refrigerant pressures. See "VIII.B. 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.
is complete. The pump-out frequency control (S4 dip switch 5 & 6) 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 cycle, or every 2, 5, or 10 cycles. For details, see "III.C.4. Pump‑Out Frequency Control (S4 dip switch 5 & 6)." 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).
C. 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.
D. Bin Control Check 1. Thermostatic Bin Control Check TBC shuts down the icemaker within 10 sec. when ice contacts the thermostatic bulb, regardless of the cycle at activation. NOTICE When the ambient temperature is below 45°F (7°C), TBC opens and shuts down the appliance even if the ice storage bin is empty. When BC is set in the prohibited range, the appliance operates continuously even if the ice storage bin is filled with ice.
2. Mechanical Bin Control Check and Cleaning a) Mechanical 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 TBC, 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 and base cover, then clear any ice away from MBC. 4) Check MBC wire harness connections. See Fig. 1.
b) Mechanical Bin Control Cleaning Scale may build up on MBC. Scale can cause the actuator paddle and magnet to stick. In this case, MBC 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 into the dispense unit/ice storage bin. 1) Turn off the power supply. 2) Remove the front panel and base cover, then move the control switch to the "OFF" position. 3) Clear any ice away from MBC.
E. 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.
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 base cover, then disconnect one end of the pump tubing to drain the water tank. See Fig. 3. After the water tank has drained, reconnect the pump tubing.
F. 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.
