to OFF.
Press POWER or turn the Fan control to
an active setting.
5.
The local power has failed.
Wait for power to be

Too many appliances are being used on the same

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 the unit off.
Wait at least 3
minutes after turning the unit off 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, pinched cord
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 runs too long
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 (CEER) and
capacity rating (in BTU/hr.) 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.
