• Air conditioner cooling, but room is too warm - ice forming on cooling coil behind decorative front.
• Air conditioner heating but room too cool.
• Air Conditioner will not operate on Cool, Fan or Heat settings.

1. Air conditioner cooling, but room is too warm - ice forming on cooling coil behind decorative front.

• Air directional louvers positioned improperly.
  Position louvers to direction upward and away from cooling coils.
  
  
• Dirty air filter - air restricted.
  Clean filter.
  
  
• Door, windows, registers, etc. open - cold air escapes; hot air enters.
  Close doors, windows, registers, etc.
  
  
• Electri-Saver in ON position.
  Set Electri-Saver to OFF.
  
  
• Front of unit is blocked by drapes, blinds, furniture, etc. - restricts air distribution.
  Clear blockage in front of unit.
  
  
• Insufficient cooling capacity.
  Reconfirm the required cooling capacity with your dealer.
  
  
• Outdoor temperature below 70 degrees F.
  To defrost the coil, turn selector switch to FAN position. After coils have defrosted, set thermostat to a warmer position.
  
  
• Selector switch set on Low-Cool.
  Turn switch to High - Cool.
  
  
• Thermostat set too cold for "nighttime" cooling.
  To defrost the coil, turn selector switch to FAN position. After coils have defrosted, set thermostat to a warmer position.
  
  
• Thermostat set too warm (lower number).
  Turn thermostat clockwise to colder setting (higher number).
  
  
• Unit recently turned on in hot room.
  Allow additional time to remove "stored heat" from walls, ceiling, floor and furniture.
  
  
• Vent control (some models) set at Open position.
  Turn control to Closed position for maximum cooling.
  

2. Air conditioner heating but room too cool
   

• Air directional louvers positioned improperly.
  Position louvers to direction upward and away from cooling coils.
  
  
• Dirty air filter - air restricted.
  Clean air filter
  
  
• Doors, windows, register, etc. open - hot air escapes; cold air enters.
  Close doors, windows, registers, etc.
  
  
• Front of unit is blocked by drapes, blinds, furniture, etc. - restricts air distribution.
  Clear blockage in front of unit.
  
  
• Insufficient heating capacity for area to be heated.
  Reconfirm the required heating capacity with your dealer.
  
  
• Room temperature is warm enough.
  Heating will not occur until temperature at the thermostat is lower.
  
  
• Thermostat set too cool (higher number).
  Turn thermostat counterclockwise to warmer setting (lower number).
  
  
• Unit recently turned on in cool room.
  Allow additional time to heat walls, ceiling, floor and furniture.
  
  
• Vent control (some models) set at Open position.
  Set control to Closed position for maximum heating.
  

3. Air Conditioner will not operate on Cool, Fan , or Heat settings.

• House fuse blown or circuit breaker tripped.
  Replace fuse with time delay type or reset circuit.
  
  
• Thermostat set to low for cooling or too high for heating.
  Adjust thermostat to higher number for cooling, lower number for heating.
  
  
• Wall plug disconnected.
  Push plug into wall outlet.

4. Air from unit does not feel cold on Cool setting.

• Selector switch is in the FAN position.
  Turn switch clockwise to Cool position.
  
  
• Temperature sensing tube touching cold coil, located behind air filter (some models only).
  Straighten tube so it does not touch coil and/or insert sensing tube into mounting bracket on coil.
  
  
• Thermostat set too warm (lower number)
  Turn thermostat clockwise to colder setting (higher number).
  
  
• Thermostat temperature below 70 degrees F.
  Cooling may not occur until temperature at thermostat rises above 70 degrees F.

5. Air from unit does not feel warm enough on heat setting.

• Selector switch in Fan or Cool position.
  Turn selector switch counterclockwise to Heat position.
  
  
• Thermostat set too cool (higher number).
  Turn thermostat counterclockwise to warmer setting (lower number).

6. Noise when air conditioner operates on cooling.

• Air sound.
  Air sound is normal. If too loud, turn selector switch to lower fan setting.
  
  
• Sound of fan hitting water- moisture removal system.
  This is normal when humidity is high. Close door, windows, registers, etc.
  
  
• Window vibration - poor installation.
  Refer to installation instructions - check with installer.

7. Water dripping inside when air conditioner is cooling.

• Improper installation.
  Tilt air conditioner slightly to the outside to allow water drainage. Refer to installation instructions - check with installer.

8. Water dripping outside when air conditioner is cooling.

• Unit removing large quantity of moisture from humid room.
  This is normal during excessively humid days.
