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 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/heat room in cooling/heating 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.

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. Push the Exhaust control Closed for maximum cooling.

The Temp control is not at a cool enough setting. Adjust the Temp control to a cooler setting by pressing the minus button to reduce the temperature. Set the Fan Speed control to the highest setting.

The air conditioner in the heating mode has insufficient Btu/h for the heating requirements of the room. Do not use the air conditioner as a primary source of heat.

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.
