Qualifier Probable Cause Corrective Action
Remove top cover from Remote Refrigeration
Unit. Examine the Agitator Motor Assembly, in-
sure propeller is secured to Agitator and that
the Agitator Switch is in the on position, al-
lowing the water in Bath to be agitated across
the cooling coils. If Motor or Propeller is inop-
erative, replace.
If ice is present on Evaporator Coil and Agita-
tor Motor Assembly is operating the Refrigera-
tion System is functioning. However, the Cir-
culating System may not be functioning. Refer
to Troubleshooting Section 3: Circulating Sys-
tem.
Caution: Always make certain that proper line
voltage is present.
Check to insure Refrigeration Switch is in the
on position.
Locate Circuit Breaker box and identify proper
breaker for Remote Refrigeration Unit. Insure
it is in the on position by switching off
and then on again. If breaker will not reset,
refer to Troubleshooting Section 6: Electrical
System.
Inspect Time Delay Fuses at the wall quick shut-
off panel. One of the fuses may be burned out
causing half the unit to shut down. If this is
suspected replace all of the fuses.
Examine High Pressure Control to insure wire
leads are securely attached to terminals. If
trouble is suspected with control, replace.
Remove Electrical Access Panel and using a volt-
meter across the Ice Bank Control, verify con-
trol is in the closed position. If control is
found to be in the open position, that Con-
trol should be replaced.
Remove Electrical Access Panel. Use a voltme-
ter across Contactor Coil. If current exists across
Coil, and Contactor remains open, Contactor
is defective. Replace.
Examine Relay/Capacitor/Overload to insure
wire leads are securely attached to terminals.
Replace any faulty components.
If after checking each of the above items, you
still experience problems, test compressor for
possible defects or grounding.
