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. Use extreme caution and exercise safe electrical practices. • Moving parts (e.g., fan blade) can crush and cut. Keep hands clear. • CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after the appliance is serviced.
2. Diagnostic Procedure This 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 appliance nameplate, and adequate water supply (10 PSIG to 113 PSIG). Check that both the 24VAC circuit fuse and the 115VAC GM fuse are good. Note: • When checking high voltage (115VAC), always choose a neutral (W) wire to establish a good neutral connection.
7) Startup–"POWER OK" LED is on: Move the power switch to the "ON" position, then move the control switch to the "ICE" position. CB "POWER OK" LED is on. IMPORTANT! Appliance will not start unless the safety switch is engaged. "POWER OK" LED Diagnosis: Check that CB "POWER" LED is on. If not, check for proper power supply voltage (115VAC) input to CT. If 115VAC is not present, check the breaker, power switch, and safety switch.
9) Ice Purge Cycle – "GM" LED is on. 5-sec. GM delay timer and 30‑min. freeze timer start. WV de-energizes and "WTRIN" LED turns off. Once the 5‑sec. GM delay timer terminates, GM, CCR, and EH (if applicable) energize. CCR cannot energize unless GM circuit is complete (GM external protector and GM internal protector). Once CCR energizes, CB K9 #5 W/O and CB K9 #6 W/O 5VDC circuit closes and ice purge timer starts (1‑min. or 5-min.). See "II.C.2a)c) Compressor Control Relay (CCR).
11) Refill Cycle/Low Water Safety – As ice is produced, the water level in the reservoir drops. UFS opens. Nothing occurs at this time. When LFS opens, WV energizes, 90‑sec. low water safety timer (fill timer) starts. Comp, GM, CCR, and FM continue. When UFS closes, WV de-energizes, 90-sec. low water safety timer (fill timer) terminates and 30‑min. freeze timer resets. If UFS remains open 90 sec. after WV energizes (fill timer exceeded), a 90-sec. shutdown cycle starts.
C. Control Board Check Before replacing a 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. Before proceeding, check for proper voltage per appliance nameplate. Check that the 24VAC 1A fuse is good and 115VAC 2A (DCM-300/500) or 3A (DCM-751/752) GM external protector is closed. NOTICE! Control Board Change: • Control board 2A4296-01 and 2A8054-01 are no longer available.
• "DRAIN" Position: When control switch is in the "DRAIN" position, CB K9 pin #1 (W/BK) and pin #2 (W/BK) are closed. 0VDC is present between CB K9 pin #1 (W/BK) and CB K9 pin #2 (W/BK). If 5VDC is present, check control switch position and continuity. If open, replace control switch. Next, confirm 5VDC is present between both CB K9 pin #1 (W/BK) and pin #2 to CB K4 pin #1 (pin closest to CB black K3). If 5VDC is not present at both locations and control switch continuity is closed, replace CB.
2b) 5VDC CB K8 Connector: See Fig. 2. a) Bin Control (BC) CB K8 pin #3 (GY) and #4 (GY): When BC is closed (icemaking), 5VDC is present between CB K8 pin #3 (GY) and pin #4 (GY) to CB K4 pin #1 (pin closest to CB black K3). If 5VDC is not present on either pin, replace CB. If 5VDC is present on pin #3 (GY) and not on pin #4 (GY), BC is open. See "II.D. Bin Control Check.
2c) 5VDC CB K7 Connector: See Figs. 3, 4, 5, and 6. a) Water Dispense Switch/Water Dispense Sensor 1. Push Button Model CB K7 pin #3 (BR) or (W/BK) and pin #8 (DBU) or (P): Before engaging the water dispense switch, check for the correct VDC from the locations given in the "Disengaged" column in the table below.
