Air conditioner seems to run too much
The current air conditioner replaced an older model. The use
■
of more efficient 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
air conditioners, but this is not an indication of lesser cooling
capacity or efficiency. Refer to the efficiency 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. A
higher-capacity air conditioner may be required, depending
on the size of the room being cooled.
Air conditioner cycles on and
off too much or does not cool
the room in cooling mode
The air conditioner is not properly sized for your room. Check
■
the cooling capabilities of your room's air conditioner. Room
air conditioners are not designed to cool multiple rooms.
The filter is dirty or obstructed by debris. Clean the filter.
■
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 air intakes are blocked. Install the air conditioner in a
■
location where the louvers are free from curtains, blinds,
furniture, etc.
The temperature of the room you are trying to cool is
■
extremely hot. Allow extra time for the air conditioner
to cool off a very hot room.
Windows or doors to the outside are open. Close all windows
■
and doors.
The temperature setting is not set to a cool enough setting.
■
Adjust the temperature to a cooler setting by pressing the
DOWN button to reduce the temperature. Set the Fan control
to the highest setting.
Error codes in display
If E1 or E2 appears in the display, call for service.
■
If FL appears in the display, empty the water bucket.
■
Remote control not working
Check the battery level display on the remote. If necessary,
■
replace the batteries.
Make sure the remote is pointed at the air conditioner and that
■
nothing is blocking the remote sensor window on the control
panel.
