  • Page 13 4) Startup/Fill Cycle–Move any ice away from the BC actuator paddle (located at the top of the bin). Move the flush switch to the "ICE" position. X5 relay and WV energize. Reservoir fills, LFS closes, nothing happens at this time. The reservoir continues to fill. X5 Relay Diagnosis: Check that WV energizes and fills the reservoir.
  • Page 14 7) Refill/Low-Water Safety Cycle–As ice is produced, water level in the reservoir drops. UFS opens, nothing happens at this time. LFS opens and refill begins. X4 relay de-energizes, low water safety circuit opens (X4 relay #4 (DBU) and #6 (BR), and CB #3 (BR) and #4 (DBU)), CB 90 sec. low-water safety timer starts. WV energizes. Comp, FM, GM, and X3 relay continue.

    2b. Diagnostic Procedure Auxiliary Code C-1 and Later This diagnostic procedure is a sequence check that allows you to diagnose the electrical system and components. Before proceeding, check for correct installation, adequate water supply (minimum of 10 PSIG, maximum of 113 PSIG), and proper voltage per appliance nameplate.
  • Page 16 5) Ice Purge Cycle–UFS closes, X11 relay energizes, WV de-energizes, and low-water safety circuit (CB #3 and #4) closes. GM and X12 relay energize, 60 sec. Comp delay timer starts. X11 Relay Diagnosis: Check for 35VDC at X11 relay #4 (DBU) to #6 (BR). If 35VDC is present, X11 relay is de-energized or bad.
  • Page 17 8) Shutdown–Ice fills ice storage bin and presses BC actuator to open BC. Comp, FM, GM, and X12 relay continue. X10 relay and X11 relay de-energize. 90 sec. low-water safety timer starts. When 90 sec. low-water safety timer terminates, Comp and FM de-energize.

    C. Control Board Check Before replacing a control board 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. 1) Startup: Move the power switch to the "OFF" position, then unplug the appliance. Access CB and remove the wires from CB #3, 4, 5, 6, 10, and 11.

    C. Relays X5 (C-0 and earlier) and X10 (C-1 and later)- Control Relay: Relay energizes when power switch is "ON," safety switch closed (if applicable), safety relay (if applicable) de-energized, BC closed, and flush/control switch in "ICE" position. Once energized, relay allows 24VAC to X4 relay (C-0 and earlier) or X11 relay (C-1 and later) for WV initiation and prevents DV from energizing during icemaking process.
