Portable Air Conditioner
Troubleshooting
Caution: Do not try to repair your portable air conditioner yourself. Doing so invalidates the warranty.
PROBLEM POSSIBLE CAUSE POSSIBLE SOLUTION
Air conditioner does not
start
The air conditioner is
unplugged.
Make sure that the air conditioner is plugged in
and that the plug is pushed completely into the
outlet.
The fuse on the circuit is
blown or the circuit breaker is
tripped.
Check the house fuse/circuit breaker box and
replace the fuse or reset the circuit breaker.
Power failure.
If a power failure occurs, the air conditioner turns
off. When the power is restored, wait three minutes
to restart the air conditioner to prevent tripping
the compressor overload.
The current interrupter
device in the power cord has
tripped.
Press the RESET button located on the power cord
plug. If the RESET button will not stay engaged,
discontinue use of the air conditioner and contact a
qualified service technician.
FL appears on the display.
The water collection tank is full and must be
drained. Drain the tank and reset your settings. See
“Emptying the water collection tank“ on page 16.
Room temperature is less
than the set temperature.
This is normal. The air conditioner automatically
shuts off when the room temperature equals, or is
less than, the set temperature. Adjust the
temperature setting, if needed.
The air conditioner does
not cool
Airflow is restricted.
Make sure that there are no curtains, blinds, or
furniture blocking the front of the air conditioner.
The temperature control may
not be set correctly
In COOL mode, decrease the temperature setting
by pressing the
button on the panel or the
remote control.
The air filter is dirty.
Clean the filter at lease every two weeks. See
“Cleaning and maintaining your air conditioner” on
page 15.
The room may have been
hot.
You need to allow time for the room to cool down
after you first turn on the air conditioner.
The exhaust hose is not
connected or is blocked.
Connect the exhaust hose and make sure that it is
not obstructed and is functioning properly.
The air conditioner is
freezing up
The cooling coils are iced
over.
Ice may block the air flow and obstruct the air
conditioner from properly cooling the room. Set
the mode control to High Fan or High Cool.
The air conditioner runs
too often or too long
The area to be cooled is too
large for the air conditioner.
Contact Insignia Customer Care for the air
conditioner capacity required to cool the desired
area.
Doors or windows are open. Make sure that doors and windows are closed.
The venting hose is hot
When the air conditioner
runs continuously for a long
time, the hose becomes hot.
This is normal.
The air conditioner is too
loud
The unit may seem rather
loud for the first two or three
minutes of operation.
This is the sound of the compressor starting up and
is normal.
A soft, swishing noise can be
heard immediately after
turning the unit on or off, and
during operation.
This is the sound of the liquid refrigerant flowing in
the unit and is normal.
The air conditioner
makes an odd noise
An audible gurgling noise
may be heard when the unit
is operated on a gently
sloping floor.
Place the unit on a level floor.
