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 a grounded
3 prong outlet. See “Electrical Requirements.”
■ 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.”
■ 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 On/Off button has not been pressed. Press ON/OFF.
■ 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.
■ You are trying to restart the air conditioner too soon after
turning off air conditioner. Wait at least 3 minutes after
turning off air conditioner before trying to restart the air
conditioner.
■ You have changed modes. Wait at least 3 minutes after
turning off air conditioner 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. If the power cord fails to reset, contact a
service technician.
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
■ Is there a door or window open? Keep doors and windows
closed.
■ 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.
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 “Portable Air Conditioner Use.”
Air conditioner runs, but does not cool
■ The filter is dirty or obstructed by debris. Clean the filter.
■ 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 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.
