the unit in the morning
before the area gets hot,
and continue to run the unit

Troubleshooting continued

Issue
My air conditioner is
not cooling at all
My air conditioner
blows cold air, but
does not lower the
room temperature
My unit displays an
Error Code
Possible Cause
Unit is not operating in
cooling mode
The compressor is not
on
The ambient
temperature is too high
The filter may be dusty
or blocked
Blocked exhaust port
The unit is not vented
The area of the room
is too large
Open windows and
doors
Too many heat
sources
The room/garage may
be inadequately
insulated
The ambient
temperature is too high
Direct sunlight is
heating the room
The filter may be dusty
or blocked
Dirty condenser coils
Obstructed air intake
or exhaust ports
Sensor error or water
reservoir is full
Solution
Set the unit to be in
cooling mode, and
lower the set
temperature (pg. 11)
The compressor may
take up to 3 minutes to
turn on, or longer if it is
too warm
Lower the room
temperature to be
below 90°F degrees
Clean the filters.
(pg. 15)
Remove any
obstructions in the
exhaust hose and port
The unit must be
vented. (pg. 4)
Minimize the size of
the area to be cooled,
i.e. adding a drop
ceiling. Use more than
one unit to cool the
area, or use a larger
unit
Close any open doors
and windows
Remove or shut off
additional heat
sources such as radio
equipment, servers,
etc.
Properly insulate the
room to be cooled, i.e.
using fiberglass
The unit may not work
if the room
temperature is above
90°F
Close curtains or pull
down blinds, and
minimize the direct
sunlight into the room
Clean the filter and
replace it if needed
Carefully vacuum the
coils clean
Remove anything
blocking the ports
