f) High Voltage (7-beep alarm)
The maximum allowable supply voltage for this icemaker is limited by the high voltage
cut-out. When high voltage (147.5Vac ±5% or more) is present, the "POWER OK" LED
turns off and the control board shuts down the unit and sounds a 7-beep alarm every
5 seconds. When the proper supply voltage resumes, the unit automatically starts
running again.
g) Gear Motor (8-beep alarm)
Gear motor operation is conrmed through the gear motor protect relay (control board
K1 connector). If the white/orange (W/O) wires on the control board K9 connector (gear
motor protect circuit) do not have continuity (gear motor protect relay de-energized),
the compressor relay does not energize. If the icemaker is running, and the gear motor
protect relay de-energizes, the control board shuts down the compressor and gear
motor and sounds an 8-beep alarm every 5 seconds. This alarm requires a manual
reset. Turn the power off and then on again to reset the alarm. The icemaker starts
running. The compressor starts running again when the gear motor protect relay
energizes. For further details, see "IV.B. Diagnostic Procedure."
h) Bin Control (9-beep alarm)
This alarm provides protection to prevent the icemaker from overlling the ice storage
bin. If the infrared sensor is signifying the ice storage bin is empty (yellow LED off), and
the mechanical bin control is signifying the ice storage bin is full (proximity switch open),
the control board shuts down the unit and sounds a 9-beep alarm every 5 seconds. This
alarm requires a manual reset. Turn the power off and then on again to reset the alarm.
For further details, see "IV.D. Bin Control Check."
