Annual Maintenance
Your air conditioner needs annual maintenance to help ensure
steady, top performance throughout the year. Call your local
authorized dealer to schedule an annual checkup. The expense
of an annual inspection is your responsibility.
TROUBLESHOOTING
Before calling for service, try the suggestions below to see whether you can solve your problem without outside help.
Air conditioner will not operate
■ The power supply cord is unplugged. Plug into grounded
3 prong outlet. See “Electrical Requirements.”
■ The power supply cord has tripped (Reset button has
popped out). Press and release RESET (listen for click; Reset
button will latch and remain in) to resume operation.
■ A household fuse has blown, or a circuit breaker has
tripped. Replace the fuse or reset the circuit breaker. See
“Electrical Requirements.”
■ The Power button has not been pressed. Press POWER.
■ The local power has failed. Wait for power to be restored.
Air conditioner blows fuses or trips circuit breakers
■ Too many appliances are being used on the same circuit.
Unplug or relocate appliances that share the same circuit.
■ Time-delay fuse or circuit breaker of the wrong capacity
is being used. Replace with a time-delay fuse or circuit
breaker of the correct capacity. See “Electrical
Requirements.”
■ An extension cord is being used. Do not use an extension
cord with this or any other appliance.
■ You are trying to restart the air conditioner too soon after
turning off the unit. Wait at least 3 minutes after turning off
the unit before trying to restart the air conditioner.
Air conditioner power supply cord trips (Reset button
pops out)
■ Disturbances in your electrical current can trip (Reset
button will pop out) the power supply cord. Press and
release RESET (listen for click; Reset button will latch and
remain in) to resume operation.
■ Electrical overloading, overheating, cord pinching or
aging can trip (Reset button will pop out) the power
supply cord. After correcting the problem, press and release
RESET (listen for click; Reset button will latch and remain in)
to resume operation.
NOTE: A damaged power supply cord must be replaced with a
new power supply cord obtained from the product manufacturer
and must not be repaired.
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 units, 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
■ The Mode is set to Power Saver. Use Power Saver only
when you are asleep or away from home. Use Cool and a
higher fan setting for your best comfort.
■ The air conditioner is not properly sized for your room.
Check the cooling capabilities of your room 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 louvers are blocked. Install the air conditioner in a
location where the louvers are free from curtains, blinds,
furniture, etc.
Electrical Shock Hazard
Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death,
fire, or electrical shock.
