Check if ...
The power supply
cord is unplugged.
A household fuse
has blown or circuit
breaker has tripped.
The local power has
failed.
Then ...
Firmly plug the power supply cord into a live outlet with proper voltage.
Replace the fuse or reset the circuit breaker. Make sure the air conditioner is plugged into a
properly grounded outlet as described in the Installation Instructions.
Wait for power to be restored.
You can solve many common air conditioner problems easily, saving you the cost of a service call. Try the suggestions
below to see if you can solve your problem without outside help.
Air conditioner blows fuses or trips circuit breakers.
Check if ...
Too many appliances
are being used on the
same circuit.
Time-delay fuse or
circuit breaker of the
wrong capacity is
being used.
An extension cord is
being used.
You are trying to
restart the air
conditioner too soon
after turning it off.
Then ...
Unplug or relocate appliances that share the same circuit.
Replace with a 15-amp time-delay fuse or circuit breaker of the correct capacity. See
“Electrical requirements” in the Installation Instructions for the correct capacity.
Do not use an extension cord with this or any other appliance.
Wait at least 3 minutes after turning air conditioner off before trying to restart the
air conditioner.
Air conditioner seems to run too much.
Check if ...
The current air
conditioner replaced
an older model.
The air conditioner is
in a heavily occupied
room or heat-
producing
appliances are in
use in the room.
Then ...
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 BTUs/hr.) marked on the air conditioner.
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.
Troubleshooting
Air conditioner will not operate.
