Table 46 — Compressor Control Troubleshooting

*30GX251, 265 sizes have two Circuit A discharge and liquid valves.

SYMPTOMS

CAUSE

REMEDY

COMPRESSOR DOES NOT
RUN

Power line open
Control fuse open
High-Pressure Switch (HPS) tripped

Tripped motor overload
Loose terminal connection
Improperly wired controls
Low line voltage

Compressor motor defective

Seized compressor
Pre-lubrication not successful

Check main disconnect.
Check control circuit for ground or short. Replace fuse.
Move LOCAL/OFF/REMOTE switch to OFF position
then back to LOCAL or REMOTE position.
Check the controls. Find cause of trip. Reset overload.
Check connections.
Check wiring and rewire.
Check line voltage. Determine location of voltage drop
and remedy deficiency.
Check motor winding for open or short. Replace
compressor if necessary.
Replace compressor.
Check oil pump operation, oil pressure transducer, verify
oil level/flow switch operation.

COMPRESSOR CYCLES
OFF ON LOW PRESSURE

Loss of charge
Bad transducer
Low refrigerant charge
Failed expansion device

Repair leak and recharge.
Replace transducer.
Add refrigerant.
Repair/replace as needed.

COMPRESSOR SHUTS
DOWN ON HIGH PRESSURE
CONTROL

High-pressure switch erratic in action
Compressor discharge valve partially closed
Condenser fan(s) not operating (air cooled units)
Condenser coil plugged or dirty (air cooled units)
Condenser water valve not operating (water
cooled units)
Circuit overcharged
Liquid valve closed*

Replace switch.
Open valve or replace if defective.
Check wiring. Repair or replace motor(s) if defective.
Clean coil.
Check wiring. Repair or replace valve if defective.

Clean condenser.
Open valve or replace if defective.

UNIT OPERATES LONG OR
CONTINUOUSLY

Low refrigerant charge
Control contacts fused
Partially plugged or plugged expansion valve or
filter drier
Defective insulation
Service load exceeding design capacity
Inefficient compressor

Add refrigerant.
Replace control.
Clean or replace.

Replace or repair.
Keep doors and windows closed.
Check loader solenoid valves. Replace if necessary.

SYSTEM NOISES

Piping vibration
Expansion valve hissing

Compressor noisy

Support piping as required.
Add refrigerant.
Check for plugged liquid line filter drier.
Replace compressor (worn bearings).
Check for loose compressor bolts securing compressor to
cooler.

COMPRESSOR LOSES OIL

Leak in system
Mechanical damage to rotors

Find and repair leak.
Replace compressor.

HOT LIQUID LINE

Shortage of refrigerant due to leak

Repair leak and recharge.

FROSTED LIQUID LINE

Shutoff valve partially closed or restricted

Open valve or remove restriction.

COMPRESSOR LOADERS
NOT WORKING PROPERLY

Burned out coil
Defective capacity control valve
Miswired solenoid

Replace coil.
Replace valve.
Rewire correctly.
