ISSUE
POSSIBLE CAUSES
AIR CONDITIONER NOT
COOLING ROOM, OR NOT BLOWING
COLD AIR
• Be sure unit is not too large or too small for the area of the room.
• Verify that all doors, windows, curtains and any other openings are closed off.
Verify nothing is obstructing the front grille of unit, such as curtains, etc.
• Allow enough time for room to cool, especially if outside temp is very high.
• Check that the filter is not dirty and louvers are open all the way and blowing in the
desired direction.
• Check that unit is set to COOL mode and that temperature is down enough (but
not too low).
• If unit is near a heat source, such as a stove, etc., then relocate unit.
• If air coming from unit is cool to the touch, then unit is working properly; please
double check the first three bullet points above.
• If using Follow Me remote feature, move remote away from unit.
• Temperature sensor behind air filter touching cold coil. These two elements should
not be touching. Carefully straighten tube away from coil.
• Unplug unit for at least 5 minutes. Follow Reset instructions on plug.
AIR CONDITIONER COOLING
BUT ROOM IS TOO WARM - ICE
FORMING ON COOLING COIL
BEHIND DECORATIVE FRONT
• Outdoor temperature is below 64ºF (18ºC). To defrost the coil, set to FAN
only mode.
• Air filter may be dirty. Clean filter. Refer to Care and Cleaning section. To defrost,
set to FAN only mode.
• Thermostat is set too cold for night-time cooling. To defrost the coil, set to FAN
only mode. Then, set temperature to a higher setting.
AIR CONDITIONER CYCLING ON
AND OFF TOO FREQUENTLY OR
NOT ENOUGH
• Be sure unit is not too large or too small for the area of the room.
• Remove grille and make sure the temperature sensor is not too close to the coils.
These two elements should not be touching. Carefully straighten tube away
from coil.
• Make sure nothing is blocking the grille or side vents.
• Make sure there is no dirt or debris inside the unit or on the filter.
UNIT WILL NOT TURN ON
• Reset circuit breaker. Make sure there are not too many items (i.e. lamps, TV’s,
etc.) working off the same breaker.
• Check plug connection.
• If plug is operating on an on/off switch, be sure that the switch is ‘on’.
• Timer is set for the TIMER ON mode. If the air conditioner is set for Switch-On
operation mode, it will not start operating before the set time is reached.
• If the ambient temperature is lower than 61°F (16°C), the auto protection function
of the unit will prevent it from the cooling operation.
• If you have just turned the unit off, wait at least 3 minutes before restarting it.
The unit will not allow you to power it on during this 3-minute period. This is a
protection feature of the unit.
• Try plugging unit into another outlet.
• Unplug unit for at least 5 minutes. Follow Reset instructions on plug.
UNIT BLOWS FUSES OR POPS
CIRCUIT BREAKER
• Make sure there are enough available amps on the circuit for the air conditioner.
• Large units which run on a 230v will require a dedicated 20 or 30 amp circuit.
• A dedicated power outlet is required for air conditioners.
AIR CONDITIONER IS
MAKING NOISES
• Check to be sure the unit is free from debris such as leaves, sticks, etc. Verify
nothing is obstructing the unit.
• Check the fan blade for cracks or chips.
• Make sure the unit is properly and securely mounted inside the window or wall.
• Clean the air filter.
WATER PUDDLES INSIDE UNIT OR IS
COMING INTO ROOM
• Adjust the slope of the unit so that it drains downward toward the exterior of the
home. (See Installation Instructions.)
• Make sure that there is no debris blocking the drainage area of the unit.
• If the air conditioner operates in high humidity for a long time, moisture may be
condensed and appear at the air outlets.
WATER DRIPPING OUTSIDE
• Unit is removing a large quantity of moisture from a humid room. This is normal
during excessively humid days.
