Fault
Possible Causes
Remedies
Set temperature cannot be
adjusted.
The zone control set temperature
limits is reached.
Check the upper and lower temperature
limits are set correctly. See operation
manual for details on setting upper and
lower temperature limits.
Occasional wishing noise can
be heard on heating cycle.
This is the sound of the gas
changing directions as de-ice cycle
begins.
This is a normal function of an air
conditioner. The unit is removing any ice on
the outdoor unit.
The compressor is running but
the system is not cooling.
You are in heating mode.
Check the temperature settings.
The reversing valve has jammed
between heating and cooling.
Replace reversing valve.
The outdoor coil keeps freezing
over.
Outdoor coil sensor might be
faulty. See sensor (temperature/
resistance) table and check
resistance value.
Replace faulty sensor.
May have obstruction in outdoor
coil.
Remove obstructions.
There is only one condenser fan
working.
The fan is faulty. Test the fan motor
for correct voltage, check the
motor winding resistance, open
circuit, check capacitor, etc.
Replace faulty fan. If the fan motor needs
to be replaced and there isn’t one available
immediately, then just disconnect the fan
electrically and cover the faulty motors fan
guard. This way the unit can still operate at
reduced capacity using 1 fan until you get a
replacement fan motor.
The system is short on gas.
You’ve fixed the leak and want
the system to operate at 100%
so gas charge can be corrected.
What can you do to ensure 100%
compressor operation?
You can adjust your wall controller
temperature so you have a large
differential. This will operate
at the system at 100% till the
temperature gets to within 4
o
C of
the set point.
NOTE:
Ensure the the Quiet mode option
is disabled.
Select Cooling or heating mode.
If cooling adjust setpoints more than 4
o
C
lower than room temp. If Heating adjust
setpoints more than 4
o
C higher than room
temp. Complete refrigerant charging
procedure until finished.
The indoor unit gives out odour.
This happens when smell of the
room, furniture, or cigarettes
are absorbed into the unit and
discharged with the airflow.
If this happens, we recommend you to
run the air conditioner on cooling for a
period of time with the doors and windows
open or have the indoor unit washed by a
technician. Consult the installer from whom
you bought the air conditioner.
Check the drain is not piped into
the sewerage drain line.
Re-pipe drain with a P-Trap and connect
into household drainage or storm water
drain.
