Service
To save time and expense, check the following before calling an authorized service center.
Insufficient Cooling
• Turn Master Control to OFF.
• Shut all windows and doors in room.
• Remove any obstructions from inside and outside louvers.
• Close Vent Door (available on some models).

filter, may ice up and block the airflow. This is a common
occurrence in air conditioners caused when the outside
temperature drops below 70°F (21°C) while the humidity
remains high. If this happens, simply turn the unit off and allow
the ice to melt, then resume normal operation.
