Troubleshooting Guide
This troubleshooting guide is not a comprehensive analysis of the Scroll compressor refrigeration system. The aim is
to give operators simple instructions on basic unit processes so that they have the technical knowledge to identify and
bring defective operations to the notice of qualied technicians.
Problems Symptoms Problem causes Action Recommended
(A) Compressor does not start up
Compressor terminals are live but
motor does not start
Motor burned out Replace compressor
Contactor motor no operational
Coil burned out or broken
contactors
Replace contactor
No current ahead of motor
contactor
(a) Power cut
(b) Mainpowersupplyswitchedo
Check fuses and connection. See
why system tripped. If system is
operational, switch on main power
supply
Current ahead of fuse, but not on
contactor side
Fuse blown
Check motor insulation. Replace
fuse
Low Voltage reading on
voltameter
Voltage too low Contact Power Supply Utility
Starter coil not excited Regulation circuit open
Locate regulation device which
has tripped out and see why. See
instructions concerning this device
Compressor does not run.
Compressor motor “groans”
High pressure switch tripped to
contacts open on high pressure.
Discharger pressure too high
Compressor sticking (damaged or
sticking components)
Discharge pressure too high
See instructions for “discharge
pressure high”
(B) Compressor stops - Low Pressure switch tripped
Low refrigerant temperature or
low refrigerant pressure cut out
Anti-freeze security tripped
Discharge pressure too high.
Notenoughcoolinguid.Water
owtoevaporatortoolow

contact in water
Compressor stops High
Pressure switch tripped
Over current thermal relay tripped
Motor temperature thermostat
tripped
Anti-freeze security tripped
Discharge pressure too high.
(a) Voltage too low
(b) Cooling demand too high, or
condensing temperature too
high.
(c) Notenoughcoolinguid.

(a) Contact Power Supply Utility
(b) Repair leak. Add refrigerant.

(C) Compressor stops just after its start
Suction pressure too low.
Filter drier iced up
Filter drier clogged Replacelterdrier
(D) The compressor keeps running without stopping
Temperature too high in areas
requiring air-conditioning
Excess load on cooling system
Check thermal insulation and
air-tightness of areas requiring
air-conditioning
Chilled water temperature output
too high
Excess cooling demand on system
Check thermal insulation and
air-tightness of areas requiring
air-conditioning
