COOLING TROUBLESHOOTING CHART

DISCONNECT ALL POWER TO UNIT BEFORE SERVICING. CONTACTOR MAY BREAK ONLY ONE SIDE. FAIL-

URE TO SHUT OFF POWER CAN CAUSE ELECTRICAL SHOCK RESULTING IN PERSONAL INJURY OR DEATH.

SYMPTOM

POSSIBLE CAUSE

REMEDY

Unit will not run

• Power off or loose electrical connection

• Check for correct voltage at compressor contactor in control

box

• Thermostat out of calibration-set too high

• Reset

• Failed contactor

• Check for 24 volts at contactor coil - replace if contacts are

open

• Blown fuses

• Replace fuses

• Transformer defective

• Check wiring-replace transformer

• High pressure control open (if provided)

• Reset-also see high head pressure remedy-The high pressure

control opens at 610 PSIG

• Interconnecting low voltage wiring damaged

• Replace thermostat wiring

Condenser fan runs, compressor

• Loose connection

• Check for correct voltage at compressor -

If still open, replace the compressor.

• Low voltage condition

• At compressor terminals, voltage must be within 10% of rating

plate volts when unit is operating.

• Low voltage condition

• Increase voltage

Insufficient cooling

• Improperly sized unit

• Recalculate load

• Improper airflow

• Check - should be approximately 400 CFM per ton.

• Incorrect refrigerant charge

• Charge per procedure attached to unit service panel.

• Air, non-condensibles or moisture in system

• Recover refrigerant, evacuate & recharge, add filter drier

• Incorrect voltage

• At compressor terminals, voltage must be within 10% of rating

plate volts when unit is operating.

Compressor short cycles

• Incorrect voltage

• At compressor terminals, voltage must be ± 10% of

nameplate marking when unit is operating.

• Defective overload protector

• Replace - check for correct voltage

• Refrigerant undercharge

• Add refrigerant

Registers sweat

• Low evaporator airflow

• Increase speed of blower or reduce restriction - replace air
