Troubleshooting Guide
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).
• Inspect filter and clean if dirty.
• Turn Thermostat and Master Controls to coolest settings.
Under certain conditions the cooling coils directly behind the
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.
Insufficient Heating- Heating Models Only
• Turn Master Control to OFF.
• Shut all windows and doors in room.
• Remove any obstructions from inside and outside louvers.
• Close Vent.
• Turn Thermostat to Warmer and Master Control to HI HEAT.
Unit Fails to Start
• Turn Master Control to OFF.
• Replug line cord plug into outlet to be sure electrical contact
is being made. (If firm contact is not being made, outlet may
have to be replaced).
• Turn Master Control to HI FAN. If air circulating fan does not
operate, check house circuit breaker (or fuses).
