Symptom: Machine Stopped
Possible Cause
Possible Remedy
Power failure or interruption
Check fused disconnect or circuit breaker
supplying power to the machine. If power has
been off, make sure the crankcase heater is
energized and there is no liquid refrigerant in
the compressor crankcase prior to restarting the
compressor. If ice is in the freezer, initiate a
manual harvest.
Circuit breaker (CB4) for control circuit
tripped
Check compressor crankcase heater, coils of
relays, contactors, starters, solenoid valves, and
thawing timer for a ground. Repair or replace
any defective part and reset circuit breaker.
Make sure there is no liquid refrigerant in the
compressor crankcase prior to restarting the
machine.
Compressor motor starter overload tripped
Check for a loose connection on all motor
starter and motor terminals that could cause
excessive amp draw. Reset overload and
restart the machine, check amperage, power
supply, and head pressure. (Check delay timer
in part wind starts only).
Water pump, cutter motor, conveyor motor,
overload tripped
Check for loose connection on all terminals,
which could cause excessive amp draw. Reset
the overload and manually run that particular
motor to check actual voltage and amperage
against motor rating.
Freezer water pump motor overload (2MOL)
tripped
Check for loose terminal connections and reset
the overload and start the pump by turning the
selector switch (1SS) to HAND. Check voltage
and amperage against motor rating. Confirm
proper rotation.
Cutter motor overload (3MOL) tripped
Check for loose terminal connections and
reset the overload. Clear all ice that may have
jammed cutter. Turn the selector switch (1SS)
to HAND and push the MANUAL HARVEST
button. Check voltage and amps against motor
rating. If tripping repeats but ice is not
jammed, check the gear reducer for resistance,
cutter bearings for wear, drive gear and ring
gear for proper engagement, and reducer motor
for defect or single phasing.
Bin level control (optional) open
Adjust or replace control as required. If bin
level control is not used, make sure jumper
wire #8 and #9 is installed at of the terminal
block.
