Welbilt Manitowoc RCU1075, Technician'S Handbook, Page: 141 / 288

Part Number 000007661 Rev02 02/20 141
HI AMPS - GEAR MOTOR AMPERAGE EXCEEDS 3.8 AMPS
Soft Error
The control board stops the ice machine, energizes the Hi
Amps & Service lights and initiates a time delay period.
The ice machine will restart after the 60 minute delay. The
ice machine continues to run if amperage remains below
3.8 amps for six hours.
Hard Error
Gear motor amperage exceeds 3.8 amps a second time,
within six hours of the first failure. The ice machine must
be reset by pressing the control board reset button.
HI PRESSURE
Soft Error
If the refrigeration pressure exceeds 425 psi (2930 kPa)
the ice machine will turn off, energize the Hi Press light
and initiate a 60 minute delay period. If the refrigeration
pressure is below 295 psi (2034 kPa) at the end of the
delay period the ice machine will restart.
DRAIN CLOG
Soft error
When the drain sensor (located in the drain pan behind
the drain solenoid) detects water, the ice machine will
energize the Drain Clog light and turn off until reset.
