TROUBLE CAUSE REMEDY
4.13 Compressor does not start
(no hum), condensor fan motor does not
run and no ice bank.
A. There is a five minute compressor and
condenser fandelay.
B. Faulty refrigeration relay PCB.
C. Ice bank probe not completely
submerged.
D. Circuit breaker tripped.
E. Inadequate voltage.
F. PCB malfunctioning.
G. Incorrect wiring.
H. Faulty ice bank probe.
I. Transformer failure.
J. Ice bank probe not connected properly
to PCB.
A. Allow for a five minute delay to lapse.
B. Replace refrigeration relay PCB in
control box.
C. Fill water reservoir until water flows
from overflow tube.
D. Reset breaker. If problem persists,
1) determine reason and correct,
2) electrical circuit overloaded; switch to
another circuit.
E. Measure voltage across common and
run terminal on compressor. Voltage must
not drop below 90% of rated voltage.
F. Replace PCB assembly.
G. Refer to wiring diagram and correct.
H. Replace ice bank probe.
I. Reset circuit breaker on top of control
box. If breaker trips again, see Section
8.22.
J. Connect ice bank probe to PCB.
4.14 Compressor does not start
(no hum), but condenser fan motor
runs.
A. Compressor relay or overload
malfunctioning.
B. Inadequate voltage.
C. Incorrect wiring.
D. Compressor malfunctioning.
A. Replace compressor relay or overload.
B. Measure voltage across common and
run terminal on compressor. Voltage must
not drop below 90% of rated voltage.
C. Refer to wiring diagram andcorrect.
D. Replace compressor.
4.15 Compressor does not start but
hums.
A. Inadequate voltage.
B. Incorrect wiring.
C. Compressor relay
malfunctioning.
D. Compressor malfunctioning.
A. Measure voltage across common and
run terminal on compressor. Voltage must
not drop below 90% of rated voltage.
B. Refer to wiring diagram and correct.
C. Replace compressor relay. Be sure to
use correct relay. Failure to use correct
relay will cause compressor failure.
D. Replace compressor or deck.
