Troubleshooting (continued)
Problem Solution
Air Conditioner seems to run too much □ A door or window is open. Keep doors and windows closed.
□ The current air conditioner replaced an older model. The use of
more efcient components may cause the air conditioner to run
longer than an older model, but the total energy consumption
will be less. Newer air conditioners do not emit the “blast” of
cold air you may be accustomed to from older units, but this is
not an indication of lesser cooling capacity or efciency. Refer to
the efciency rating (EER) and capacity rating (in Btu/h) marked
on the air conditioner.
□ The air conditioner is in a heavily occupied room, or heat
producing appliances are in use in the room. Use exhaust vent
fans while cooking or bathing and try not to use heat-producing
appliances during the hottest part of the day. Portable air
conditioners are designed as supplemental cooling to local
areas within a room. A higher capacity air conditioner may be
required, depending on the size of the room being cooled.
Air conditioner runs for a short time only, but room is not cool □ Set temperature is close to room temperature.
□ Lower set temperature. See “Operation”.
Display error code □ If the unit displays error code E5, the water container is full.
□ Drain the water, see “Draining the Air Conditioner” on page
17. After draining, the unit can be operated again.
□ If the unit displays error code E1/E2/E3/E4/E6/E7/EA, please
contact customer service.
Air conditioner runs, but does not cool □ The lter is dirty or obstructed by debris. Clean the lter.
□ Air outlet is blocked. Clear air outlet.
□ Set temperature is too high. Lower set temperature.
Air conditioner cycles on and off too much □ The air conditioner is not properly sized for your room. Check
the cooling capabilities of your portable air conditioner. Portable
air conditioners are designed as supplemental cooling to local
areas within a room.
□ The lter is dirty or obstructed by debris. Clean the lter.
□ There is excessive heat or moisture, open container cooking,
showers, etc. in the room. Use a fan to exhaust heat or moisture
from the room. Try not to use heat-producing appliances during
the hottest part of the day.
□ The louvers are blocked. Install the air conditioner in a location
where the louvers are free from curtains, blinds, furniture, etc.
