Symptom |
Problem |
Doesn't operate
immediately: |
- If the unit is stopped and
then immediately started again, the compressor will not
operate for about 3 minutes, in order to prevent fuse
blowouts.
- Whenever the Power Supply
Plug is disconnected and then reconnected to a power outlet,
the protection circuit will operate for about 3 minutes,
preventing unit operation during that period.
|
|
Noise is heard: |
- During operation and
immediately after stopping the unit, the sound of water
flowing in the air conditioner's piping may be heard. Also,
noise may be particularly noticeable for about 2-3 minutes
after starting operation (sound of coolant flowing).
- During operation, a slight
squeaking sound may be heard. This is the result of minute
expansion and contraction of the front cover due to
temperature changes.
|
- During Heating operation, a
sizzling sound may be heard occasionally. This sound is
produced by the Automatic Defrosting operation.
|
|
Smells: |
- Some smells may be emitted
from the indoor unit. This smell is the result of room smells
(furniture, tobacco, etc.) which have been taken into the a/c.
|
|
Mist or steam are emitted: |
- During Cooling or Dry
operation, a thin mist may be seen emitted from the indoor
unit. This results from the sudden cooling of room air by the
air emitted from the a/c, resulting in condensation and
misting.
|
- During Heating operation,
the outdoor unit's fan may stop, and steam may be seen rising
from the unit. This is due to Automatic Defrosting operation.
|
|
Airflow is weak or stops: |
- When Heating operation is
started, fan speed is temporarily very low, to allow internal
parts to warm up.
- During Heating operation, if
the room temperature rises above the thermostat setting, the
outdoor unit will stop, and the indoor unit will operate at
very low fan speed. If you wish to warm the room further, set
the thermostat for a higher setting.
|
- During Heating operation,
the unit will temporarily stop operating (between 7 and 15
minutes) as the Automatic Defrosting mode operates. During
Automatic Defrosting operation, the OPERATION indicator lamp
will flash.
|
- The fan may operate at very
low speed during Dry operation or when the unit is monitoring
the room's temperature.
|
- During SUPER QUIET
operation, the fan will operate at very low speed.
|
- In the monitor AUTO
operation, the fan will operate at very low speed.
|
Water is produced from
the outdoor
unit: |
- During Heating
operation, water may be produced from the outdoor unit due to
Automatic Defrosting operation.

Symptom |
Items to Check |
|
Doesn't operate at all: |
- Is the Power Supply Plug
disconnected its outlet?
- Has there been a power
failure?
- Has a fuse blown out, or a
circuit breaker been tripped?
|
|
|
|
Poor Cooling or Heating
performance: |
- Is the air filter dirty?
- Is the air conditioner's
intake grille or outlet port blocked?
- Did you adjust the room
temperature settings (thermostat) correctly?
- Is there a window or door
open?
- In the case of Cooling
operation, is a window allowing bright sunlight to enter?
- In the case of Cooling
operation, are there heating apparatus and computers inside
the room, or are there too many people in the room?
|
- Is the unit set for SUPER
QUIET operation?
|
|
The unit operates differently from
the Remote Control Unit's setting: |
- Are the Remote Control
Unit's batteries dead?
- Are the Remote Control
Unit's batteries loaded properly?
