CONDENSERS

FAULT

POSSIBLE CAUSE

REMEDY / ACTION

Unit will not start

No power

Check power supply to the controller

Wired incorrectly

Check wire connections in accordance

with wiring diagram on control box lid

Loose wires

Check all wires, connections,

terminals etc

Head pressure too high

Condenser coil clogged or dirty

Clean condenser

Overcharge of refrigerant, normally

troublesome in warm weather

Reclaim excess refrigerant from

system

Air or other non-condensable gas in

system

Evacuate system and re-charge with

new refrigerant

Head pressure controller faulty

Refer to Indoor unit

Fan not operating or operating

inefficiently

Refer to Indoor unit

Head pressure too low

Fan operating too fast in low ambient

conditions

Refer to Indoor unit

Condenser fan not operating - power

Power supply failure

Check power supply at circuit breaker

Wiring to motor

Check voltage at motor terminals

Motor / fan assembly jammed

Isolate unit and check free rotation of

motor/fan assembly, if faulty - replace

Motor internal overheat protector

tripped

Carry out continuity check at terminals

“TK” in motor terminal box, if tripped

and motor hot - check bearings, if

tripped and motor cold - replace motor

Faulty motor windings/capacitor

Motor humming would indicate fault in

motor or capacitor, check windings for

continuity and if OK replace capacitor

Minimum speed set too low

Refer to Indoor unit

Faulty pressure sensor

Check electrical connections are

secure at controller and pressure

sensor, replace controller and sensor

(as they are matched sets)

Faulty fan speed controller

Refer to Indoor unit

Condenser fan runs too fast

High ambient condition or excessive

re-circulation of air around condenser

coil

Check installation against design

Minimum set speed setting incorrect

Adjust as necessary

Incorrect pressure sensor setting

Adjust sensor screw as necessary

Faulty fan speed controller

Refer to Indoor unit

Faulty pressure sensor

Refer to Indoor unit

Condenser fans runs only slowly

Incorrect pressure setting

Adjust sensor screw as necessary

Faulty fan speed controller

Refer to Indoor unit

Faulty pressure sensor

Refer to Indoor unit

Motor/capacitor faulty

Replace
