SYMPTOM

CAUSE

REMEDY

Compressor and condenser fan will not start.

Power failure

Call power company

Fuse blown or circuit breaker tripped

Replace fuse or reset circuit breaker

Defective contactor, transformer, or high--pressure,

loss--of--charge or low--pressure switch

Replace component

Insufficient line voltage

Determine cause and correct

Incorrect or faulty wiring

Check wiring diagram and rewire correctly

Thermostat setting too high

Lower thermostat temperature setting below

room temperature

Compressor will not start but condenser fan

runs

Faulty wiring or loose connections in compressor cir-

cuit

Check wiring and repair or replace

Compressor motor burned out, seized, or

Determine cause

internal overload open

Replace compressor

Defective run/start capacitor, overload, start relay

Determine cause and replace

One leg of 3--phase power dead

Replace fuse or reset circuit breaker

Determine cause

Low input voltage

Determine cause and correct

Three--phase scroll compressor

Scroll compressor is rotating in the wrong direction

Correct the direction of rotation by reversing the

makes excessive noise, and there may be a

low pressure differential.

3--phase power leads to the unit. Shut down unit

to allow pressures to equalize.

Compressor cycles (other than normally sat-

isfying thermostat)

Refrigerant overcharge or undercharge

Recover refrigerant, evacuate system, and re-

charge to capacities shown on rating plate

Defective compressor

Replace and determine cause

Insufficient line voltage

Determine cause and correct

Blocked outdoor coil

Determine cause and correct

Defective run/start capacitor

Determine cause and replace

Faulty outdoor fan motor or capacitor

Replace

Restriction in refrigerant system

Locate restriction and remove

Compressor operates continuously

Dirty air filter

Replace filter

Unit undersized for load

Decrease load or increase unit size

Thermostat temperature set too low

Reset thermostat

Low refrigerant charge

Locate leak, repair, and recharge

Air in system

Recover refrigerant, evacuate system, and re-

charge

Outdoor coil dirty or restricted

Clean coil or remove restriction

Excessive head pressure

Dirty air filter

Replace filter

Dirty condenser coil

Clean coil

Refrigerant overcharged

Recover excess refrigerant

Air in system

Recover refrigerant, evacuate system, and re-

charge

Condenser air restricted or air short--cycling

Determine cause and correct

Head pressure too low

Low refrigerant charge

Check for leaks, repair, and recharge.

Restriction in liquid tube

Remove restriction

Excessive suction pressure

Refrigerant overcharged

Recover excess refrigerant

Suction pressure too low

Dirty air filter

Replace filter

Low refrigerant charge

Check for leaks, repair and recharge

Metering device or low side restricted

Remove source of restriction

Insufficient evaporator airflow

Increase air quantity

Check filter–replace if necessary

Temperature too low in conditioned area

Reset thermostat

Outdoor ambient below 55



F (13



Install low--ambient kit

Filter drier restricted

Replace filter
