PROBLEM
CAUSE
REMEDY
6.11 Compressor starts and continues
to run until
freeze up and will not cut off.
A. PCB malfunctioning or faulty ice
bank probe.
B. Ice bank probe positioned
improperly.
C. Ice bank probe shorted to ground.
A. Disconnec ice band probe from
PCB.
1. If compressor continues to run,
replace PCB.
2. If compressor stops, replace ice
bank probe.
B. Check positioning of ice bank
probe, and replace if needed.
C. Replace ice bank probe.
NOTE:
First, check to ensure that the three (3) minute carbonator timer has not timed out. Turn unit OFF and then ON.
If the pump shuts off in less than 30 seconds, the dispenser is not frozen.
6.12 Warm drinks
A. Restricted airflow.
B. Dispenser connected to hot water
supply.
C. Refrigeration system not running.
D. Refrigerant leak.
E. Condenser fan motor not working.
F. Dirty condenser.
G. Dispenser capacity
exceeded.
A. Check clearances around sides,
top, and inlet of unit. Remove objects
blocking airflow through grill.
B. Switch to cold water supply.
C. Refer to Items 6.16 through 6.20.
D. Repair and recharge.
E. Replace condenser fan motor.
F. Clean condenser.
G. Add pre-cooler, or replace with
larger dispenser.
6.13 Compressor does not start (no
hum), condenser fan motor does not
run and no ice bank.
A. There is a five (5) minute compres-
sor and condenser fan delay.
B. Ice bank probe not completely
submerged.
C. Circuit breaker or fuse tripped.
D. Inadequate voltage.
E. PCB malfunctioning.
F. Incorrect wiring.
G. Faulty ice bank probe.
H. Transformer failure.
I. Ice bank probe not connected
properly to PCB.
A. Allow for five (5) minute delay to
lapse.
B. Fill water reservoir until water flows
from overflow tube.
C. Reset breaker or replace fuse. If
problem persists:
1. Determine reason and correct.
2. Electrical circuit overloaded;
switch to another circuit.
D. Measure voltage across common
and run terminal on compressor. Volt-
age must not drop below 90% of rated
voltage.
E. Replace PCB assembly.
F. Refer to wiring diagram and correct.
G. Replace ice bank probe.
H. Reset transformer circuit breaker.
If breaker trips again, refer to
Item 6.20.
I. Connect ice bank probe to PCB.
