Troubleshooting Tips...
Before you call for service
Save time and money! Review the charts on the following pages first and you may not need to call for service.
Problem
Possible Cause
What To Do
Air conditioner
does not operate.
The unit is unplugged.
Plug into a 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
on some devices, a green light will turn on) to resume operation.
A household fuse has blown, or circuit
breaker has tripped.
Replace the fuse or reset the circuit breaker. If the problem
continues, call an electrician. See “Electrical Requirements.”
The Power button has not been pressed
or the Mode control knob is turned to Off.
Press POWER or turn the Mode control knob to an active
setting.
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
air conditioner.
Wait at least 3 minutes after turning off the 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 on some devices, a green light will turn on) 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 on some devices, a green
light will turn on) 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
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.
Air conditioner
cycles on and off
too much or does
not cool room in
cooling mode
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.
The outside temperature is below 65°F
(18°C).
Do not try to operate your air conditioner in the cooling mode
when the outside temperature is below 65°F (18°C).
The temperature of the room you are
trying to cool is extremely hot.
Allow extra time for the air conditioner to cool off a very hot
room.
Windows or doors to the outside are open.
Close all windows and doors.
The Temperature control is not at a cool
enough setting.
Adjust the TEMP/TIME control to a cooler setting by pressing
the minus button to reduce the temperature. Set the Fan Speed
control to the highest setting.
Water drips from
cabinet into your
house
The air conditioner is not properly
leveled.
The air conditioner should slope slightly downward toward
the outside. Level the air conditioner to provide a downward
slope toward the outside to ensure proper drainage. See the
Installation Instructions.
NOTE:
Do not drill a hole into the bottom of the metal base and
condensate pan.
