Troubleshooting
The following symptoms do not indicate malfunction.
Symptom Cause
POWER indicator blinks before the unit is
switched on.
• This is the preliminary step to prepare for the TIMER
operation after it has been set.
When Timer is set ON, the unit may start earlier (up to
35 minutes) before the actual set time to achieve the
desired temperature on time.
POWER indicator blinks during HEAT mode
with no warm air supply (and flap is closed).
• The unit is in defrost mode (and AIR SWING has been
set to AUTO).
POWER indicator blinks, then stops blinking
during COOL/DRY mode.
• The system has been locked to operate in HEAT mode
only.
TIMER indicator is always ON. • When Timer has been set, the Timer setting repeats
daily.
Operation is delayed a few minutes after
restarting.
• The delay is a protection to the unit’s compressor.
Cooling/heating capacity is reduced during
lowest fan speed setting.
• The lowest fan speed is to have a low noise operation,
so cooling/heating capacity may be reduced depending
on the condition. Increase the fan speed to increase the
capacity.
Indoor fan stops occasionally during heating
operation.
• To avoid unintended cooling effect.
Indoor fan stops occasionally during automatic
fan speed setting.
• This is to help remove the surrounding odour.
Airflow continues even after operation has
stopped.
• To extract the remaining heat from the indoor unit
(maximum 30 seconds).
The room has a peculiar odour. • This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
Cracking sound during operation. • Changes in temperature caused the unit to expand and
contract.
Water flowing sound during operation. • Refrigerant flow inside the unit.
Mist emerges from indoor unit. • During cooling operation, the discharged cold air may
condense to water vapour.
Outdoor unit emits water or steam. • During cooling operation, condensation occurs on
cold pipes and the condensed water may drip from the
outdoor unit.
• During heating operation, frost formed on the outdoor
unit during deice cycle melts and is discharged as
water or steam.
Discoloration of some plastic parts. • Discoloration is subjected to the types of materials
used in plastic parts. It is accelerated when exposed to
heat, sun light, UV light or environmental factors.
Soft buzzing sound from indoor unit during
nanoe™X operation.
• It is normal when the nanoe™X generator is working.
If you are concerned about the sound, cancel the
nanoe™X operation.
Wireless LAN indicator is ON when the unit
is OFF.
• The unit’s wireless LAN connection with the router has
been activated.
