REMEDY
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.Voltage must
not drop below 90% of rated voltage.
E. See Section 6.
F. Refer to wiring diagram and correct.
G. Replace ice bank probe.
H. Reset transformer circuit breaker. If
breaker pops again, refer to Sec. 4.23.
I. Connect ice bank probe to PCB.
A. Replace compressor relay capacitors
or overload.
B. Measure voltage across commom and
run terminal on compressor. Voltage must
not drop below 90% of rated voltage.
C. Refer to wiring diagram and correct.
D. Have the unit repaired by a qualified
service technician.
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 starting relay or capacitors.
Be sure to use correct rating. Failure to
use correct rating will cause compressor
failure.
D. Have the unit repaired by a qualified
service technician.
