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 heatproducing 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.

■ 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 air conditioner. Wait at least 3 minutes after
turning off the air conditioner before trying to restart the air
