Troubleshooting

You can solve many common air conditioner problems easily, saving you the cost of a service call. 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 grounded 3-prong outlet. See “Electrical Requirements.”

•The power supply cord trips (Reset button will pop 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. See “Electrical Requirements.”

•Depending on model, the Power button has not been pressed or the Fan Speed control is turned to Off. Press POWER button or turn the FAN SPEED control 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 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 on some devices, a green light will turn on) to resume operation.

•An electrical overloading, overheating, 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. A damaged power supply cord 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 units, but this is not an indication of lesser cooling capacity or efficiency. Refer to the efficiency rating (EER) 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.

Air conditioner cycles on and off too much or does not cool

•The Mode is set to Power Saver (on some models). Use Power Saver only when you are away from home or asleep, since the fan does not circulate the room air continuously. Use Low, High or Turbo for your best comfort.

•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.

•The inside evaporator and outside condenser coils are dirty or obstructed by debris. See “Annual Maintenance.”

•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 Exhaust control is set to OPEN (on some models). Push the Exhaust control CLOSED for maximum cooling.

•Depending on model, the Temp/Time or 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 or adjust the TEMPERATURE control to a cooler setting by turning the knob clockwise. Set the FAN SPEED control to 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 in the bottom of the metal base and condensate pan.
