■ 9 Troubleshooting

In general, possible trouble is classified in three kinds. One is called Starting Failure which is caused from an electrical defect, another is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application, and the other is called the Structure Damage.

POSSIBLE CAUSES	Solution
UNIT DOES NOT STARTUnit may have become unpluggedFuse may have blownCircuit breaker may have been trippedUnit may be offUnit may be in a protection mode.	Check that plug is plugged securely in wall receptacle.Note: Plug has a test/reset button on it. Make sure that the plug has not tripped.Replace the fuse. See Note 1.Reset circuit breaker. See Note 1.Turn unit on (bottom right button on keypad).
UNIT NOT COOLING/HEATING ROOMUnit air discharge section is blockedTemperature setting is not high or low enough.Note: Set point limits may not allow the unit to heat or cool the room to the temperature desired. Check section on dip switch settings.Unit air filters are dirty.Room is excessively hot or cold when unit is started.Vent door left open.Unit may be in a protection mode.Compressor is in time delay.	Make sure that curtains, blinds or furniture are not restricting or blocking unit airflow.Reset to a lower or higher temperature setting.Remove and clean filters.Allow sufficient amount of time for unit to heat or cool the room.Start heating or cooling early before outdoor temperature, cooking heat or gatherings of people make room uncomfortable.Close vent door.Check dipswitch settings for desired comfort.Wait approximately 3 minutes for compressor to start.
DISPLAY HAS STRANGENUMBERS/CHARACTERS ON IT	The unit may be in a protection mode.The unit may be set for °C (instead of °F).
UNIT MAKING NOISES	Clicking, gurgling and whooshing noises are normal during operation of unit.
WATER DRIPPING OUTSIDE	If a drain kit has not been installed, condensation runoff during very hot and humid weather is normal. See Note 2.If a drain kit has been installed and is connected to a drain system, check gaskets and fittings around drain for leaks and plugs.
WATER DRIPPING INSIDEWall sleeve is not installed level	Wall sleeve must be installed level for proper drainage of condensation. Check that installation is level and make any necessary adjustments.
ICE OR FROST FORMS ON INDOOR COILLow outdoor temperatureDirty filters	When outdoor temperature is approximately 55 °F or below, frost may form on the indoor coil when unit is in Cooling mode. Switch unit to FAN operation until ice or frost melts.Remove and clean filters.
