Temperature setting on the control panel too low. Set the ambient room temperature on the control panel.

  • When switching on cooling operation, the unit does not operate.

Temperature setting on the control panel too high. Set the ambient room temperature on the control panel.

Note, on some models:
If the room temperature is below 18°C, the compressor will not operate due to low ambient temperature. (cooling mode only)
 

  • Unusually high condensation on the unit or the cold air ducts.

Door or windows open (high humidity). Close all doors and windows during operation, set cooling to high on the control panel.

  • Unit operates for a prolonged period (heating or cooling) and then stops.
