Troubleshooting
Why is my air conditioner not functioning at all?
o Move the air conditioner to another outlet, and test the outlet with a voltage tester or another appliance
that is known to be non-defective. If the outlet is bad, contact an electrician and move the air conditioner to
another outlet.
o If the remote will not work, first, check the batteries. The control panel may be unplugged from the circuit board.
Contact customer service to repair.
Why is my air conditioner not cooling at all?
o The unit should be in a room where the ambient temperature is below 95˚F. If the ambient temperature is
above 95˚F, the unit will likely not blow cold air but is not defective. Follow the below steps to increase the
efficiency of your unit’s compressor:
o Minimize heat in the room.
o Minimize the size of the area to be cooled (close doors and windows).
o Close curtains or pull down blinds; minimize direct sunlight into the room.
o Remove additional heat sources such as computer equipment (servers), etc.
o Run the unit before it is needed (e.g., run the unit in the morning before the area gets hot, and
continue to run the unit all day long in order to maintain a low temperature).
o Use more than one unit or a larger unit to cool the area.
o Remove the exhaust hose and run the unit for 5 minutes. Stick your hand in front of the exhaust and then
in front of the internal air louvers. Is the exhaust noticeably hotter than the interior air? If so, the unit is not
defective; follow the above steps to maximize efficiency of your unit’s compressor.
o If your unit has a filter, the filter may be dusty or otherwise blocked. Clean the filter or contact customer
service to replace if necessary.
o Check to make sure the air intake or exhaust ports are not partially obstructed. If they are, remove the
obstruction.
My unit turns on, but one of the fans is not turning or makes a loud noise? (Exhaust and evaporator fan)
o If the fan spins freely while the unit is off, but does not spin when the unit is on, then the probable
cause is a loose wire from the fan motor to the circuit board, or a faulty fan motor. Contact customer
service to replace faulty wiring or fan motor.
o If the fan does not spin freely, then the probable cause is a broken fan, or a foreign object has
jammed the fan. Contact customer service if fan is broken, or unplug unit and attempt to remove
foreign object.

The air conditioner may not be receiving electrical power. Press the test/reset buttons on the LCDI power
cord.
