GM and GMPR energize. 5-min. IPT starts. GM runs for 5 min. to clear any ice from the evaporator. Diagnosis: If "GM" LED is off, check that UFS closed. If UFS is closed and "GM" LED does not turn on, replace CB. If "GM" LED is on and GM is off, confirm 115VAC at CB K1 connector pin #2 (BR) to neutral (W).
  • Page 16 12) Drain Cycle–"FLUSH" (drain) LED is on. IMPORTANT! Drain valve will not energize unless the safety switch is engaged. The appliance is factory set to drain the evaporator and reservoir once every hour for 2 seconds. A manual drain is provided when cleaning the appliance by moving the control switch from the "ICE" position to the "DRAIN" position. A 1-in-12 drain cycle is also available. For further details, see "III.C. 3.
  • Page 17 13) Shutdown–Bin fills and ice engages BC actuator paddle. 6 to 10-sec. shutdown sequence begins. Diagnosis: Check that BC actuator paddle is activated and not sticking.
